This page explains which filetypes can be played back and edited in LeiaPlayer.
All of the following filetypes are supported in LeiaPlayer. It's organized by whether the filetype is 3D Lightfield or 2D, and then further divided by whether it's an image or video. All 3D formats are automatically detected as 3D, either through the file's metadata or through an automatic computer vision algorithm for unlabelled 3D files.
Leia Image Format (LIF)
Leia Image Format images (abbreviated as LIF) are JPG images with image metadata that may contain depth, bokeh data, and one or more images known as "views"
These images can be shared anywhere to any device and will automatically show as a high-resolution 2D image on all standard computing devices like laptops or phones. However, they will automatically be displayed as 3D Lightfield images on Lume Pad and other Leia devices
They are optimized for Lightfield View Mode by default. You can view them in stereo 3D view mode (if the LIF file has 2 views) by using the ST button in LeiaPlayer
This is the default image format in the Leia ecosystem, and offers the most flexibility long-term. When you edit an SBS image in LeiaPlayer, it will automatically save as LIF
3D SBS Images
Two Side-By-Side images
Left image on the left, right image on the right
File formats supported: JPG, PNG, WEBP, HEIC
Quad Lightfield Images
Four images shot in a horizontal line aligned in quadrants in the following order:
Top Left Quadrant: Outer left image
Top Right Quadrant: Inner left image
Bottom Left Quadrant: Inner right image
Bottom Right Quadrant: Outer right image
File formats supported: JPG, PNG, WEBP, HEIC
Quad Lightfield images will not be interpolated in any way, they will always be displayed exactly as-is in Lightfield View Mode
Quad Lightfield should generally only be used by creators who understand the ins and outs of Leia Lightfield displays and know how to push the capabilities of the Lume Pad to its limits
Apple Portrait Mode Images
When a user takes a Portrait Mode image on an iOS device using the iOS Camera app, it may include an embedded depth map making it a true 3D file. If LeiaPlayer finds a depth map in a photo from iPhone, you can convert the file to LIF by simply tapping the Lightfield View Mode button
Tip: You can tell if a depth map will be captured when taking a photo in Portrait Mode on the iOS Camera app if the icon that says "NATURAL LIGHT" on-screen turns yellow. If it's grey, no depth will be captured
Tip: Newer iOS devices and especially iOS devices with LiDar take the highest-quality depth maps. Older devices may not be able to capture depth maps or will take poor quality depth images
Legacy 3D Images
Support for MPO and JPS filetypes
Support for two images embedded in an MPO or JPS image (files with 1 or 3+ images may not be supported)
They look like standard 2D images on many non-3D devices
MPO is most commonly captured on Fujifilm FinePix Real 3D cameras, Nintendo 3DS and 2DS devices, and other 3D cameras from that era
JPS is most commonly captured using Nvidia 3D Vision tools, such as in-game screen captures, and from other 3D software for PC
Automatic Detection of SBS and Quad Lightfield Images:
In the case that the automatic file detection feature didn't correctly identify your your SBS or Quad Lightfield image and shows it in 2D, you can force LeiaPlayer to treat image files as SBS or Quad by using the Manual 3D Tagging feature inside the app or by doing the following:
SBS: Append "_2x1" to the end of the filename before the file extension
Half-width SBS: Append "_half_2x1" to the end of the filename before the file extension
Quad Lightfield: Append "_2x2" to the end of the filename before the file extension
3D SBS Videos
Two Side-By-Side videos
Left image on the left, right image on the right
File formats supported: MP4, MKV, WEBM, H4V
SBS videos will open in Lightfield View Mode and be automatically interpolated to 4 views when viewed in LeiaPlayer on Lume Pad. You can use the ST button to view in the original stereo format with 2 views.
Quad Lightfield Videos
Four images shot in a horizontal line aligned in quadrants in the following order:
Top Left Quadrant: Far left image
Top Right Quadrant: Middle left image
Bottom Left Quadrant: Middle right image
Bottom Right Quadrant: Far right image
File formats supported: MP4, MKV, WEBM, H4V
Quad Lightfield images will not be interpolated in any way, they will be displayed exactly as-is in Lightfield View Mode
Quad Lightfield should generally only be used by creators who understand the ins and outs of Leia displays and know how to push the capabilities of the Lume Pad to it's limits
Automatic Detection of SBS and Quad Lightfield Videos:
In the case that the automatic file detection feature didn't correctly identify your your SBS or Quad Lightfield video and shows it in 2D, you can force LeiaPlayer to treat video files as SBS or Quad by using the Manual 3D Tagging feature inside the app or by doing the following:
SBS: Append "_2x1" to the end of the filename before the file extension
Half-width SBS: Append "_half_2x1" to the end of the filename before the file extension
Quad Lightfield: Append "_2x2" to the end of the filename before the file extension
These standard 2D image formats are supported in LeiaPlayer. You can also automatically convert any of them into 3D by tapping the Lightfield View Mode button in the view switcher in the bottom left of the UI. This will create a LIF copy of the image.
JPG
PNG
WEBP
HEIC
These standard 2D video formats are supported in LeiaPlayer. You can also automatically convert any of them into 3D by tapping the Lightfield View Mode button in the view switcher in the bottom left of the UI. This is real-time conversion and will not alter the file or make a 3D copy.
MP4
MKV
WEBM
This page describes the filetypes that LeiaCam captures.
JPEG: All 3D images captured in LeiaCam are saved in the Leia Image Format with the file extension .jpeg at the end of the filename. All 2D images taken are standard JPEG photos.
What is Leia Image Format? Leia Image Format (a.k.a. LIF) is a JPEG picture that is encoded with extra information making the image viewable as a Lightfield image. Leia devices will automatically identify LIF files as a 3D image and display them in Lightfield view mode. Leia Image Format is fully backwards compatible as a 2D image on all non-Leia devices. If you send or upload a LIF through a platform that compresses images, depth information may be lost.
MP4: All videos captured in LeiaCam are saved in the MP4 format with the file extension .mp4 at the end of the filename.
SBS: If the video is taken with settings that enable 3D, the MP4 will be encoded in SBS (Side by Side) format, which is a 3D filetype where one video per eye is encoded side by side, the left eye on the left, and the right eye on the right. These files will automatically be detected on Leia devices as 3D videos. They may be backwards compatible with other 3D devices, but may require extra filename tagging or manual option selection to show the file in 3D. On 2D devices, you will be able to play back the SBS file, however you will see both the left and right eye video on the screen at the same time.
This page describes the options available when editing images in LeiaPlayer.
The Depth slider controls the disparity value of your image. As you move the slider up, you will perceive more depth
Disparity is the difference in image location of the same 3D point when projected under perspective to two different camera views
Perception of depth arises from the “disparity” of a given 3D point in your right and left retinal images
The Focus slider controls the convergence value of your image.
As you move the slider up, more objects in your image will appear to be popping out of the front of the screen
As you move the slider down, more objects in your image will appear to be moving backward behind the screen
The convergence value is the point at which the left and right eye images align, which sets the location of convergence at the screen plane
Objects in front of this point will appear to be in front of the screen and those behind will appear to be behind the screen
The bokeh slider controls the digital blur applied to background pixels that are located behind the convergence plane
If you move the convergence slider to the very top, there are no pixels considered as behind the convergence plane, and thus aren’t part of the background
Thus you won’t see any digital blur applied to those pixels, even if you move the Bokeh slider to the very top
If you feel the need to increase the depth of your image a considerable amount to the point where you start to see visual artifacts in the background, you can add some bokeh, as it will blur the background and help conceal the artifacts.
These are primarily straightforward chroma editors that you will see in any mobile photo editing app
This will increase the brightness of all shadows and highlights in your image
Your photo will look brighter overall as you move the slider up
This will increase the photo’s color intensity
The colors in your photo will look more intense as you move the slider up
Contrast is the range of difference between different tones in a photo
For black and white photos, contrast describes the difference between the darkest and lightest tones
For color photos, contrast applies to how sharply colors stand out from one another
As you move the slider up, bright colors will appear brighter
As you move the slider down, dark colors will appear darker
Adjusting the Hue slider to see shifts in the color values in your images
You can radically alter your photos colors
Smaller, more incremental adjustments can effectively reduce unwanted color casts and correct the photos white balance
Color Pop will remove color from pixels considered as part of the background
This makes the colors of objects in the foreground really standout
This is the only feature in the Color section that makes use of the disparity map
Simple tools for resizing and rotating your image.
Note that if you crop an image down to a smaller size, its disparity and convergence values will increase, which will increase the depth sensation
This is where the artistic flavor gets added
Tap any of the relighting presets, and you will have different lighting configurations added to your image.
These lighting placements use the depth map to get placed into different parts of the image.
After applying a preset and hitting the check button to confirm your changes, you can open the Relighting section again and add another preset. This will let you create custom presets by combining multiple presets together. If you keep adding them, your pictures will start to take on a very different tone.
Apply styles to your images by selecting the preset filters.
As with relighting, you can apply multiple presets to each image to create your own custom styles.
Combine these filters with a bunch of relighting presets to make each image a unique work of art
Capture 3D Lightfield photos and videos with a tap.
When you launch the app, you will open into Photo Capture Mode in 3D
Tap the white capture button to take a photo
Photos captured by the Lume Pad's Rear Stereo Camera saved in 3D will be in the LIF format (a type of JPEG), which you can view in Leia apps in 3D or anywhere else in 2D
Camera Switch
Tap the camera switch button to switch between the front and rear camera
Preview Image
Tap the image preview icon in the bottom right corner to view your image in LeiaPlayer
Tap Videos tab to change to video capture mode
Tap the white and red capture button to take a video
Videos can be captured in 3D or 2D by changing the selection in the Settings in the bottom lefthand corner
Grid View
Tap the Grid Off button to turn on the rule of thirds grid
Rule of thirds is a common compositional technique that divies your frame into an equal, 3x3 grid with two horizontal and vertical lines that intersect at four points
Place your subject on the left-third or right-third of the frame to create a pleasing composition
Flash
By default, the camera flash will be turned off
Tap the flash off icon to view 3 options: flash on, flash off and auto-flash

Get the final app updates for the world's first Lightfield tablet.
The original Lume Pad came out in 2020, and was a non-tracked "4V" device (4x4 views for a total of 16 views) glasses-free 3D Android tablet. After running the Leia Appstore for Lume Pad (2020) for four years, we're stopping support in July 2024, two years after we stopped selling the device. For your convenience, we will be providing download links to the final versions of Leia apps on Lume Pad (2020), and links to a few other popular apps, with no warranty or support, either express or implied. You will be using these apps at your own risk.
All links to Lume Pad app APKs are available at the bottom of this page.
Lume Pad is the world’s first Lightfield tablet. A crisp, comfortable 10.8-inch Lightfield display offering a no-compromise experience for the Android apps you know and love as well as a suite of apps that you can see in stereoscopic 3D with the naked eye without ANY specialized eyewear required.
If you’re a creator that wants to see your content in a new light, Lume Pad provides a beautiful medium to highlight your work.
Whether you’re designing buildings, developing games, creating 3D models in new ways, or even if you’re constructing a new take on medical visualization software: the Lume Pad is the tool for you. Pictures, videos, and 3D models. All elevated to the next level with Lightfield.
It all starts here with the Lume Pad and its powerful Leia app suite.
This guide will help you understand everything you can do with your Lume Pad.
The Lume Pad is a high-quality Android tablet with a chassis made of brushed aluminum. On the back of the device you'll find the Lume Pad and LitByLeia logos, the high-quality 3D camera, and the antenna window.
On the front of the device you'll find the front-facing camera, the ToF sensor, and of course, the DLB Lightfield display.
On the right side of the device you'll find the volume rocker and the lock button, and on the top of the device you'll find the USB-C charging port.
At Leia, we’ve developed a single optical layer sculpted by nanotechnology that sits just underneath the LCD display to create the Lightfield effect, powered by what we call Diffractive Lightfield Backlighting (DLB).
With 2D content, the Lume Pad’s 10.8-inch screen projects out a bright 2560X1600 picture. When used for traditional Android apps, that 16:10 screen looks bright, sharp and, well, like a normal high-end Android tablet.
But when the DLB is activated, lights pass through it to create a dynamic Lightfield 3D effect. The light projects out four views simultaneously in 16 directions -- this is Lume Pad's Lightfield view mode. Unlike other 3D solutions, Lume Pad is brighter, thinner, can instantly switch between full-quality 2D and Lightfield 3D, and can be rotated to support every orientation while in 3D. Lume Pad is LitByLeia.
Our goal is to deliver our vision of how Lightfield can change the way we see art, engage in commerce, and affect the world.
If you want more of a breakdown of how Leia’s DLB technology works, check it out here.

The Swiss army knife of the Leia ecosystem that lets you playback, edit, and export 3D Lightfield media.
LeiaPlayer is a simple yet powerful app that lets you view, organize, and edit your 3D Lightfield media.
When you launch LeiaPlayer, you’ll find yourself in the Media gallery. The app launches directly to Media so you can easily find the images or videos you've engaged with most recently.
Media shows you all the images and videos found in your Pictures, Movies, and Downloads folders as well as any file you navigate to and open in LeiaPlayer's File Browser. You can easily remove any file from your Media tab by selecting it inside the Media tab and choosing "Remove Selection From Media". You can also easily add any file on your device to the Media tab by finding it in LeiaPlayer's File Browser and selecting "Add Selection to Media".
If you're opening LeiaPlayer for the first time, you’ll notice some preloaded media to give you inspiration on what 3D Lightfield content can look like. Note: Media will automatically add photos and videos found in the top level of your Pictures, Movies, and Downloads folders, but will not automatically add files in nested folders found inside those listed folders.
Tap the Menu Button (a.k.a. Hamburger Menu) in the top left to access the Navigation Menu Drawer. From here, you can jump between different file galleries in LeiaPlayer.
Moving down the drawer menu below Media, you'll see Camera Roll, File Browser, Lume Link, and Settings.
This is the default browsing experience in LeiaPlayer. The Media tab aggregates media on your device in one easy to use place. By default, all the image and video files in your Pictures, Movies, and Downloads folders will appear here. However, other files that you've opened in the LeiaPlayer File Browser will appear in Media automatically too, as well as media you've added using "Add Selection to Media".
This section shows you the entire file system of your device. The LeiaPlayer File Browser follows the standard file browsing paradigm from Android. The File Browser shows the folders on your device, and these folders contain subfolders within them. When you tap the “Pictures” folder you will see the “Screenshots” subfolder contained within it, alongside any media that's already in the Pictures folder.
We want to preserve this folder structure so that when you move files on or off of Lume Pad from a computer or another app, you can easily understand where they're located.
Lume Link is a feature of the LeiaLink app that allows you to send images from your mobile device to your Lume Pad and have it waiting for you in LeiaPlayer already converted into Lightfield 3D.
The Settings tab in LeiaPlayer gives you the ability to turn features on and off and customize your LeiaPlayer experience.
General: This section provides several options for how you'd like to view media in LeiaPlayer. It also gives you options on how you'd like LeiaPlayer to handle certain features that may make modifications to your files.
Video Playback: Options for default video playback behavior.
About: Licenses and legal info.
LeiaPlayer Beta: Sign up for future Beta versions of LeiaPlayer.
There are a variety of ways to add media to your Lume Pad, including downloading files from the internet, or getting a 3D Lightfield photo or video from another Lume Pad user. To add media from a computer to Lume Pad to experience in LeiaPlayer, you can use Android File Transfer on MacOS or simply plug your Lume Pad into a PC to move files from your computer onto Lume Pad. Then, you can find them in LeiaPlayer and view them.
All 2D or 3D content can be viewed in 3D in LeiaPlayer! For 3D content it's self-explanatory, but for 2D images and videos it's a little different. Still, it's as easy as tapping the Leia Lightfield button.
2D Images: Open a 2D image so it's full screen in LeiaPlayer. Tap the Leia logo in the bottom left hand corner on the View Switcher, and a new LIF format version of your image that's in 3D. You will have two files now: the original 2D image and the new 3D LIF image.
2D Videos: Open a 2D video so it's full screen in LeiaPlayer. Tap the Leia logo in the bottom left hand corner on the View Switcher, and after a few seconds of buffering, you will see your video playing back in 3D! Just follow these steps again whenever you want to view your 2D video file in 3D.
The Ellipsis Button is the three vertical dots you usually see in the top right corner of the app. The Ellipsis Menu changes depending on the context of where you are in the app.
The Ellipsis Button opens up View Options if you're in a standard Gallery View. These View Options may be available in other modes too, like in Bulk Selection Mode. These are the options available within the View Options menu:
Lightfield/2D Sorting: Show only Lightfield media files, only 2D media files, or Both.
Media Type Sorting: Show only Images, only Video, or Both.
Sort By Options: Sort by Date Created, Date Modified, Filename, File Size, or Resolution
The Ellipsis Button opens up More Options if you're in the File Browser View. These are the options available within More Options when in the standard File Browser View:
New Folder: Creates a new Folder within the Folder that you're currently in.
Select: This option will switch you into Bulk Selection Mode so you can easily select mutliple files to move or delete.
The Ellipsis Button opens into More Options in Bulk Selection Mode. Here are the options available within More Options when in Bulk Selection Mode:
Add Selection to Media: Adds the selected file to the Media tab.
Rename: You can use this option to change a file's filename (Only when 1 file is selected)
Move: This feature will move the file(s) from one folder to another (more info below)
Select None: Deselects all selected items and exits Bulk Selection Mode
Invert Selection: Deselects all currently selected items and selects all currently unselected items within the folder that you're in.
Select All: This option will select every item in the folder that you're in
Moving files from one location to another is easy. Just follow these instructions:
Long press an image thumbnail to enter Bulk Selection Mode.
Select the files that you would like to move.
Tap the Ellipsis Button (3 vertical dots) in top right corner.
Tap the Move Button in the More Options Menu.
In the Move Menu, navigate to the destination folder you want to move the file(s) to.
Tap the Move Here Button in bottom right corner to confirm the move.
The files will now be located in the destination folder you selected.
The files you selected are not being copyed, they are being moved. They will no longer be found in their original location.
The files you just moved may be hard to find if you moved them to a folder with a lot of items in them. To find the files you just moved, you may have to scroll down to the bottom of the destination folder, as the folder you moved the files to may be sorted based on the files names or the original date the files were created. The files you just moved may also not be grouped together in the destination folder.
Viewing 3D images
If you have 3D files from other sources like SBS or Quad Lightfield images or video, LeiaPlayer will try to detect them automatically. However, sometimes, LeiaPlayer may not automatically detect them as 3D. To manually communicate to LeiaPlayer that the files are 3D, you will need to use the 3D Tagging feature.
Here's how to do this in LeiaPlayer:
Open up the 3D image that's being displayed in 2D
Tap Ellipsis Button (3 vertical dots) icon in top right corner
Tap Add 3D Tag
Follow the instructions and answer questions about the file
The file will now be viewable correctly in 3D
You can do this process to fix a file that's incorrectly identified as 3D or in the wrong format of 3D too by doing the same steps except tapping the "Edit/Remove 3D Tag" button that appears in place of the "Add 3D Tag" button.
When you open an image or video in LeiaPlayer, it will open in Theater Mode. This is the best place to view 3D Lightfield media.
When viewing media, you will notice an option in the bottom left corner to change the view mode.
Lightfield: This icon looks like the Leia logo. View the compatible image or video as a 3D Lightfield with 4 unique views. Lightfield View Mode has the following benefits: a wide viewing angle, comfortable for multiple viewers, objects feel more real and have a "look-around" (parralax) effect.
ST: This icon is named for Stereoscopic 3D View Mode. The icon is only shown when viewing compatible files. View the compatible image or video in traditional stereo 3D with 2 unique views. Stereo 3D has some benefits, including: support for more depth for a single viewer, and no synthesized views. The downsides for Stereo 3D View Mode include a smaller viewing angle, much less comfortable for multiple viewers, no look-around / parallax effect, and increased chance of cross-talk/ghosting. This is the preffered viewing method for content captured on legacy 3D systems.
2D: View the image or video in standard 2D with a single view. 2D is highest resolution with maximum brightness, but of course has no depth or look-around effect/parralax.
Some Apple devices allow you to capture depth maps when shooting images in Portrait Mode and with some other apps. The quality of the depth map depends on the device, the sensors available, and the environment and distance from the subject when the image was taken.
Shoot Portrait Mode Images on your iOS device where the Portrait Mode Indicator (e.g. Natural Light icon) is yellow
Move images with Apple Depth Maps and move them to your Lume Pad (using LeiaLink, email, or other method)
Open it in LeiaPlayer
Tap the Leia Lightfield View Button to convert Apple Depth Map images to a 3D Lightfield LIF

In order to share Leia Image Format (LIF) files to another Lume Pad device and retain the 4V depth metadata, you must be cognizant of the transfer method you use. Many messaging apps and social networks will strip the 3D Lightfield metadata and send only a 2D image to the other user.
If you'd like to send the LIF file directly to another device here are some methods that work:
Supported Messaging Platforms
Discord
ZIP: If you compress or ZIP images before sending them, metadata will be retained in transit
If you want to share your Lightfield images to 2D devices, tap the share button in the gallery screen.
This will allow you to export images as Lightfield Animation in MP4 and GIF format, which are Lightfield-synthesized animations that show the depth of your images by interpolating smoothly between the image's views.
This is the best way to share your Lightfield images on traditional social media platforms.
Loop Video
To loop your video continuously, tap the ellipsis button in the top right corner
Then tap “Loop Video On”
Depth Slider
You will see the Depth Slider on the right-hand side of the screen whenever viewing video content in Lightfield view mode
Move the Depth Slider up and down to increase or decrease the disparity value, which will increase or decrease the sensation of depth
What are the benefits of editing Lightfield Images in LeiaPlayer?
Improve the visual quality of your images
Increase the depth effect of your images
Add artistic flair to your images
To edit images in LeiaPlayer, open an image and tap the pencil and pad icon in the bottom center of the screen. Only some 3D Lightfield images can be edited, including LIF and 3D SBS images.
The LeiaPlayer editor relies on the depth map to estimate the depth at each pixel in the photo, which can be used to identify portions of the image that are far away and belong to the background. Quad Lightfield images don't contain the Lightfield metadata needed to edit them.
Images are saved in the Leia Image Format, and will retain the same number of views as it originally contained.
Lume Link is a feature of LeiaPlayer that allows you send pictures directly from your linked smartphone to your Lume Pad.
The Lume Link tab on the side of LeiaPlayer allows you to connect your smartphone to your Lume Pad. Then, you can easily send pictures to your Lume Pad from your mobile device and they'll appear in 3D Lightfield in LeiaPlayer.
It's easy!
Go to the Lume Link tab in LeiaPlayer
Sign in using LeiaLogin
You'll see a pin number on-screen
Now grab your mobile device.
On your mobile device, go to your device's app store and download LeiaLink
Open LeiaLink and follow the instructions on the screen
Type your LeiaLogin account's email address into the LeiaLink app
Type the pin number on your Lume Pad into the LeiaLink app
Your Lume Pad and mobile device are now linked!
Now you can go to the image gallery on your smartphone, select images, and share them to the LeiaLink app. They will appear in the Lume Link tab in LeiaPlayer on your Lume Pad, except they'll be in beautiful Lightfield 3D!
This page explains how to convert 2D media into Lightfield 3D media in LeiaPlayer.
2D to 3D Lightfield conversion couldn't be simpler. Simply open your 2D image or video in LeiaPlayer and tap on the Leia Lightfield View Switch in the bottom left hand corner. Voila, your file is now viewable in 3D Lightfield!
For images, a 3D copy of the image will be made in the LIF format, so you'll now have the original untouched 2D file as well as a 3D LIF copy.
For video, the conversion is done in real-time and your 2D video file will remain untouched. You will need to follow the above process each time you return to your video if you'd like to view it in 3D.
If your file is a Portrait Mode image from iOS with an Apple Depth Map, the embedded depth map will be used in the 3D Lightfield conversion.
To learn more about the different filetypes, go to .
LeiaViewer supports various 3D model file formats.
Supported File Types
LeiaViewer supports the following file types:
FBX
OBJ
STL
GLB
GLTF
File Recommendations
The file size limitations in LeiaViewer are impacted by the number of triangles, polygons and vertices of each model
If your model is not loading, it may be too large to open in LeiaViewer. in this case you should try to reduce the facecount to under 100k.
You can do this by going into Blender (a free app) and using the decimate tool.
You may also want to adjust texture size down to 4K or less in Photoshop
Recommend upper limit for facecounts: 100k
Recommend upper limit for file sizes: 50MB
Recommend upper limit for textures: 4K resolution or less
If there is problem loading a 3D model on your device:
Send us the model file
Describe the problem (is it a crash, is there an error modal, did the model fail to load?)
Is the center of rotation correct
Importing Models
To import models, tap the + button in the top left corner to open the file browser
The file browser will automatically surface all of the model files located on your device
For model types like FBX and OBJ, your textures will need to be siblings of the model file.
STL doesn't have textures, so its a single model format. Just load the model by clicking on it in the file browser
Uploading OBJ & OBJ instructions
OBJ and FBX are the same, but you need to make sure any textures that come with model are in same directory as the model itself
sometimes they come with a separate textures folder, you need to move all the textures into the top level directory that contains the OBJ model
once all the files are in the right place, just tap the OBJ model in LeiaViewer file browser
Animations
Animations are not in a separate file, they are a part of models themselves
Animations are usually included in GLB, GLTF, FBX model files already
They will be shown when you open the model in LeiaViewer file browser
LeiaFrame doesn't support every kind of file yet. LeiaFrame only supports 3D filetypes, and only supports some 3D image filetypes. Here are the files supported by LeiaFrame:
LIF
SBS (2x1)
Quad Lightfield (2x2)
SBS (2x1)
Quad Lightfield (2x2)
2D photos
2D videos
MPO
JPS
VR180/360
Support for unsupported formats may be added in the future.
Many kinds of 3D filetypes can be posts to LeiaPix.
Every major 3D image format is supported by LeiaPix. This includes:
LIF (Leia Image Format)
SBS (Side by Side, 2x1)
Quad Lightfield (2x2)
MPO
JPS
Some images or formats may not be supported by every feature in every version of LeiaPix.
This page describes how to create beautiful and shareable Lightfield Animations.
You can turn any 3D image file in LeiaPlayer into a Lightfield Animation. This is a an animation that can be shared anywhere that can give others an understanding of the depth in your 3D image.
To create and share a Lightfield Animation, all you have to do is open the 3D Lightfield image that you want to turn into a Lightfield Animation, tap the Share button, and then select either "Video Animation" or "GIF Animation".
Video Animations will be in the MP4 file format and GIF Animations will obviously be in the GIF file format.
Video Animations export in higher quality but GIF Animations may be supported on platforms where sharing a video isn't. In addition, some platforms like Twitter will compress video files but will leave GIFs uncompressed. Also, GIFs play automatically, but videos may require a viewer to click or tap to play the Video Animation. Many times you'll find that there's no option to automatically loop videos on the platform you're using, while GIFs will do so by default.
The world's largest repository of Lightfield images wrapped in a social media platform with an inspiring and talented creator community.
LeiaPix is the premier social media app for Lightfield images. It houses the largest collection of Lightfield images in the world – and it's the best way to share, discuss, and discover new Lightfield content. Users post amazing, inspirational and fun images every day.
You are two checkboxes away from joining the LeiaPix community. Agree to the LeiaPix Privacy Policy, Terms of Use, and Community Guidelines, then confirm that you're 16 years of age or older. After that, use your LeiaLogin account to sign in to LeiaPix.
Whenever you start LeiaPix anew, you'll find yourself in the Home Feed.
The Home Feed can be accessed at any time whenever the Navigation Bar is visible, which is the row of icons you see at the bottom of the screen. If you're on another page and would like to access the Home Feed, press the LeiaPix Home Button in the middle the Navigation Bar (it's the button that is the LeiaPix Icon).
The Home Feed is an endless curated feed of LeiaPix content from people you follow, what's currently trending, and images the algorithm thinks you'll like based on what you've liked in the past. The Home Feed consists of the Title Bar at the top of the screen and a scrollable feed of image thumbnails of LeiaPix Posts.
If you start scrolling down, the Title Bar with the LeiaPix Logo will automatically dissapear. If you scroll up again, it will reappear. You can instantly jump back to the top of the Home Feed by tapping the LeiaPix Logo in the Title Bar. When you're at the top of the Home Feed, you can pull down to refresh the Home Feed.
While you're in the Home Feed, you can tap on any image thumbnail to enter Theater Mode.
Theater Mode is the primary method of interacting with images in LeiaPix. Almost anywhere in the app, if you see an image thumbnail, you can tap it to enter Theater Mode. This includes the Home Feed which we already mentioned, but also when in a Discover Category page, in your Notifications page, or in your Profile page, all of which we'll discuss later.
In Theater Mode, you can see the user who posted the image, the time the image was posted, and read the image's caption. There are also multiple ways to interact with the image, which are listed here:
Full Screen the image by tapping on the image itself to make the borders with buttons and information appear and dissapear
Like the image to let the person who posted it know you liked it by tapping the Heart Button
Comment on the image to start or add to a conversation by tapping on the Word Bubble Button
Bookmark the image for later viewing in the Bookmarks section of your Profile page by tapping on the Bookmark Button
Tap the Ellipsis Button for more options
Share a web link to the LeiaPix Post
If the user clicks on the link on a device with LeiaPix installed, it will open the LeiaPix app directly to the Post you shared
If the user clicks on the link on a device without LeiaPix installed, it will open the Post in LeiaPix.com as a Lightfield Animation, which is an animated 2D version of the Post
Report the Post if you believe it goes against the LeiaPix Community Guidelines
Block user will make it so that you no longer see any content from the blocked user anymore and vice versa (this can be reversed in Settings)
Export the image
Still Image exports the image in Leia Image Format, which is a 3D Lightfield image that looks 2D on any device that isn't LitByLeia
Video Animation exports the image as a Lightfield Animation in MP4 format
GIF Animation exports the image as a Lightfield Animation in GIF format
A variety of destinations are supported depending on the format you choose, including Facebook, Instagram, Twitter, Slack, WhatsApp, and more
Visit the Profile of the user who posted the image by tapping on their name or profile picture in the top left of the Theater Mode screen when the info border is visible.
You can press the Back Arrow in the bottom left corner of the Theater Mode info border to return to the page you were in before entering Theater Mode.
If you're in a view within LeiaPix that has other images in it, you can swipe up and down while in Theater Mode to see other images.
Now that you're comfortable using LeiaPix, why don't you try uploading an image yourself?
There are two major ways to Post images to LeiaPix
You can Post images already on your device's storage, whether they have been:
Taken with the LeiaCam app previously
Downloaded from an app or website
Transferred from an external drive or computer
Taken with LeiaCam from the Upload page inside the LeiaPix
To start the process, you simply press the Upload button on the far left of the LeiaPix Navigation Bar. The Upload button looks like a square with a plus [+] sign inside of it. The Navigation Bar is accessible from most screens, including Home, Discover, Notifications, and Profile. If you don't see the Upload button, press the back button until you reach a screen where the Navigation Bar appears.
When you tap the Upload button, you'll be taken to the Browse Images Page. Once you've entered the Browse Images Page for the first time, you'll be prompted to provide the app access to your files so it can upload your images to LeiaPix. Press "Allow Access" whenever prompted.
Whenever you tap the Upload Button in the Navigation Bar, you will enter the Browse Images Page showing your device's Camera folder by default. This will allow you to choose any 3D Lightfield image that was previously taken with the LeiaCam app.
To change the folder you're browsing, tap on the folder name at the top of the screen with the [v] symbol to the right of it. This will let you choose any folder on the device that has 3D Lightfield images in it. The number below the folder name tells you how many 3D Lightfield images are in it.
If you'd like to take a new picture to post, simply tap the Take Photo button on the Browse Images Page. This will open LeiaCam from within LeiaPix, and you will be able to take a 3D Lightfield image. The functions in LeiaCam that aren't supported by LeiaPix, such as video, will not work when using LeiaCam from within LeiaPix.
Once you've taken or selected an image to post to LeiaPix, tap the Next button on the top right of the Browse Images Page. This will take you to the full screen Image Preview page, which will let you confirm this is the image you'd like to post before posting. Press the Next button in the top right to continue the upload process, or press the X button in the top left to go back to the Upload Page.
When you tap Next on the Image Preview page, it'll take you to the Caption Page. Here, you can write a caption for the image you're going to upload.
Captions can include up to 240 characters of the following:
Text: Captions can have text describing the image, saying what it is, when it was taken, and other details about it.
Emojis: Emojis can be used for additional communication options within a caption.
User Mentions: You can mention or "tag" another user in your image by using the "@" symbol and beginning to type their name. Once you see their name in the menu that appears, tap on it to add them to the caption. The text of their name will turn purple if done successfully. You can use User Mentions to tag people who are in the image uploaded, give photo credit to the person who took the photo, or simply to send another user a notification to check the image out because you think it's something they might like.
Hashtags: Help group images that are similar to make them easier to discover and find. You can use the "#" symbol to create a hashtag. After using the "#" symbol, you continue to type a series of letters without spaces or punctuation to create a hashtag (e.g. #dog). Oftentimes, people will use hashtags to identify what is in the subject of the image, where the image was taken, when the image was taken, the brand of the products in the images, and other things along those lines. For example, if someone took a picture of the cheeseburger they had for lunch while on vacation in Seattle with their friends, the hashtags they use might include: #food #burger #cheeseburger #lunch #Seattle #vacation #friends
NOTE: Hashtags are not case sensitive, but will retain the case of the letters you choose before posting. e.g. Posts that have #LOSangeles and #losANGELES in their caption will both come up when you search for #losangeles, but if your caption has #LosAngeles it will show up as #LosAngeles whenever people view your Post's caption in Theater Mode.
Finally, once you're done writing your caption, you can press the Post Button in the top right to post your image to LeiaPix!
When you press the Post Button, your image will begin to upload and you will be taken to your Profile Page.
Profile Pages are the primary place where a user's LeiaPix posts live.
There are two kinds of Profile Pages: User Profiles of other users, and Your Profile, which can be accessed by pressing the Profile Button on the far right of the LeiaPix Navigation Bar.
Users usually go on the User Profile Page of another user to see all the posts from that user.
When you're on a User Profile Page of another user, you can see the following:
Their name
Their Profile Picture
Their Cover Photo (if they've set one)
Their number of Followers
The number of users Following them
Follow/Unfollow
If you're not Following the user, you'll see a Follow Button on their Profile
If you are Following a user, you'll see an Unfollow Button on their Profile
When you Follow a user, it ensures you see new posts from them in your Home Feed
Their Bio

Everything you need to know about Lightfield images on Leia devices.
Lightfield images can be found all over Lume Pad in various apps, but LeiaPlayer is your one-stop shop for viewing all the different 3D formats supported in the Leia ecosystem.
Viewing Lightfield Images You'll find all of the 2D, 3D, and Lightfield images on your device in LeiaPlayer. You can easily view them by tapping on the image thumbnails you find in the Media, Camera Roll, or File Browser tabs in LeiaPlayer. Moving media to your device To add images from other devices to your Lume Pad to view in LeiaPlayer, you have a lot of options.
If you use Google Photos, you can simply use the Google Photos app on your Lume Pad to get your favorite images and download them to your Lume Pad. The process is similar with any other cloud image service, just download the service's Android app through Google Play and download the images to your device.
If the image aren't on another service, you can use a USB cable to move them to your Lume Pad. First, get all the images to your Windows or Mac computer. Then, plug in your Lume Pad using a USB-C cable. You'll see a prompt on your Lume Pad with multiple options. Choose "Transfer Files".
If you're on a Windows PC, you'll now see Lume Pad in your Windows File Explorer. If you're using a Mac, we recommend using Android File Transfer, which you can dowload here.
Many kinds of 3D and Lightfield image filetypes are supported on Lume Pad, though different apps may have different levels of support.
A viewer for DICOM 3D models which are optimized around medical use cases. This app allows you to interact with DICOM file sets while viewing them in 3D Lightfield view mode.
Being able to bring your DICOM files to your tablet is vital for any medical professional. However, having those very same files projected as 3D holograms with depth and texture is a game changer. DICOM Viewer is your pipeline to getting the medical imaging data you need onto your Lume Pad. Take DICOM-based data - whether it’s medical scans (MRI or Ultrasound) or more - and view it in true 3D on the Lume Pad’s screen. No glasses required, you can get more context and detail in ways never before seen on a tablet.
Best of all, it’s simple to get the files prepared quickly - even when timing is critical.
For the sake of this demo, A DICOMfile can be a single file or a set of several .dcm files. Here is an example of a file set for a single DICOMmodel. Each file is a layer of the model. All files will be needed to display the model correctly.
To copy a DICOMfile over to your Lume Pad, first connect your Lume Pad to your PC or Mac via USB cable. When the popup appears saying “Use USB for” select the File Transfer option.
On your PC or Mac open the folder for your Lume Pad.
Create a folder in which you want to store the model files. “Models” will be used in this example.
For every model you plan to copy over, you’ll need to create a separate folder there.
On your PC locate the model files you wish to copy over or download them from whichever service you use (Dropbox, GDrive, Onedrive…)
If the model file is zipped, it will need to be unzipped before copying over.
Once the models have been unzipped (if needed) drag the files over to the folder you created on the Lume Pad.
Once the model files are in place, you’re ready.
Inside the DICOMviewer app, touch the Open a Dicom File button.
Click on the Hamburger icon in the upper left corner.
Click the Lume Pad storage icon (LPD-10W) > Then click on the model folder and then the folder you put the model in.
Click on any of the DCM files to open the model.
That’s all there is to it. A quick drag-and-drop operation and you’re ready to get a more detailed view of your patient’s needs.
There are many ways to edit 3D images just like 2D images, including PhotoShop, GIMP, Photopea, and more. Once you get comfortable with using LeiaPlayer, you should explore using other tools to better suit your needs too.
But for now we're going to focus on the primary method for the Leia platform: LeiaPlayer. LeiaPlayer is an incredibly robust editing tool for Lightfield photos, primarily because it will take photos of any format including LIF, SBS, MPO, and JPS. Quad Lightfield images, however, can not be edited in LeiaPlayer and must be edited elsewhere.
Editing images in LeiaPlayer
To improve the visual quality and add artistic flair to your images, open an image in the gallery and then tap the edit pencil icon. You will see 5 main editing tool sections from left to right: depth, color, resize, Styles and Relighting.
Depth
The Depth editor controls the disparity of your image
The Focus slider controls the convergence value of your image
The bokeh slider controls the blur of background pixels that are behind the convergence plane. So if you move the convergence slider to the very top, there are no pixels considered as behind the convergence plane, and thus aren’t part of the background. So you won’t see any Bokeh effect even if you increase it to the top of the slider.
If you feel the need to increase the depth of your image considerably to the point where you start to see visual artifacts in the background of the image, you can add in some Bokeh to blur the background and conceal the artifacts.
Color
These are straightforward chroma editors including brightness, contrast, saturation and hue.
Color Pop will remove color from pixels considered as part of the background, to make certain colors in the foreground and focus plane “pop”.
Resize
Simple tools for resizing and rotating your image. Note that if you crop an image down to a smaller size, its disparity and convergence values will increase, gibing it more of a depth feeling.
Relighting
This is where the artistic flavor gets added. Tap any of the relighting presets, and you will have different lighting configurations added to your image. These lighting placements use the depth map to get placed into different parts of the image.
Pro tip: after applying a preset and hitting check, you can open Relighting section again and add another preset. This lets you create custom presets by combining many of them together. If you keep adding them, your pictures will start to take on a very different tone.
Filters Apply styles to your images by selecting the presets. As with relighting, you can apply multiple presets to each image to create your own custom styles. Combine this with a bunch of relighting presets to make each image a unique work of art.
There are three major ways to create Lightfield Images:
Shoot images with a camera
Render images using a software tool
Capture images inside real-time software
You can use a variety of 2D and 3D cameras to create Lightfield images. We'll list them here from highest potential for quality to lowest.
The best way to capture Lightfield 3D images is to build a custom stereo rig using two or more high-quality cameras. Doing this is difficult, but can yield the highest quality results. The distance between the sensors, the accuracy of the synchronization, the percision of the calibration, and of course the quality of the sensors and optics all play a part in the quality of the outcome.
iPhone 13 Pro and iPhone 12 Pro series devices with LiDAR generally are expected to produce better images than LeiaCam on Lume Pad, while standard iPhone 13 and iPhone 12, as well as all iPhone 11 Pro series device and lower are generally expected to produce worse results than LeiaCam. Feel free to try and explore to see what works best yourself.
One of the best ways to create Lightfield images is with LeiaCam, which shoots images and videos with immersive depth on the Lume Pad. LeiaCam lets you capture the world around you in both Lightfield and 2D shooting modes. Take images and videos with immersive depth that pops out of the screen.
You can also use a variety of normal cameras to shoot 2D images to convert to Lightfield later. Your smartphone, a DSLR, or a mirrorless camera can all be used. You can even use a webcam!
Simply shoot the 2D image, and then move it onto your Lume Pad. Open the image in LeiaPlayer, and tap the Leia icon (Lightfield View Mode Button) in the bottom left hand corner. Voila, your formerly 2D image now has a Lightfield 3D copy!
There are a variety of software tools that let you render out a stereo 3D or Lightfield image.
In LeiaPix Converter, you can upload any image you want and it will automatically estimate a depth map. You can then edit that depth map in your browser and export it as either a LIF or an SBS to view on Lume Pad.
Some creators compose Quad Lightfield and SBS images in PhotoShop.
You can also capture 3D content from inside some of your favorite real-time apps on a variety of different hardware.
Any game that has a Photo Mode with the following features can be used to take 3D photos:
In Photo Mode, EVERYTHING on screen stops moving
In Photo Mode, you have horizontal directional control of the camera
After taking a photo in Photo Mode, the scene doesn't change in any way
Supported platforms include PC, PlayStation 4 and PlayStation 5, XBOX One and XBOX Series S/X, and Nintendo Switch.
Games that have Photo Modes that are known to work include Marvel's Spider-Man, Final Fantasy 7 Remake, and God of War. Games that are known NOT to work include Animal Crossing: New Horizons.
Here is an example of what a good 3D image can look like when captured in this method:
Some games on some platforms have built-in 3D cameras that let you natively capture from 3D from inside the app.
Platforms that support this frequently are 3D-first platforms like the PlayStation 3 and Nintendo 3DS. Games like WipEout HD on PlayStation 3 will natively capture 3D photos in MPO format when using Photo Mode to capture photos when the game is being displayed in 3D mode. Games like Animal Crossing: New Leaf, StreetPass Mii Plaza: Flower Town, and Nintendogs & Cats on Nintendo 3DS all allow for the capture of 3D screenshots in parts of the games.
The sharing process for Lightfield images is a little different depending on the recipient's device.
You can always just send a Lightfield image to another device directly. You can plug in a USB-C cable and transfer the image to another device, including a PC, Mac, or other Lume Pad. You can also move the files onto USB storage. Finally, you can use Android Nearby Share to send the file directly to another Leia device in your vicinity.
The primary filetype used on Leia devices is LIF (Leia Image Format). In a perfect world, you could just send an LIF any method you want. Unfortunately, a lot of the most popular communication platforms compress images, which turns 3D LIF files into regular 2D images.
Options for sharing LIFs:
Send an LIF through a known-good communication platform
Send a Zipped LIF through any platform
Send an SBS instead
Unfortunately, there are only a few messaging platforms that don't compress your images. They include:
Email (choose Full Size)
Discord
That's it! All the other major platforms we've tested do NOT support transmitting LIF files, as they compress all images and wipe data of images sent on them.
Slack
Signal
Telegram
Messenger
To ZIP a LIF file to send over one of the above incompatible messaging platforms, you can simply put the LIF files into a folder in the Files app on your Leia device, tap the ellipsis button (three dots in the right corner), and then tap "Compress". This will ZIP the entire folder, including the LIF files. You will be able to send this through any platform that supports basic file transfer, and when the recipient unzips the folder, they will be able to access the LIF images in full Lightfield View Mode!
If you don't wish to spend the time zipping the files, an easy way to get them onto another device is to export it as an SBS. To export the file as an SBS, simply go to the image in LeiaPlayer and tap the Share button, then choose Side-By-Side under Export Options. These will be able to be sent through any messaging platform that supports images. Two potential issues however: the platform may still compress the image which lowers it's visual quality, and the image will show two side by side images when it's recieved.
Older 3D devices and XR headsets don't support Lightfield file formats. Unfortunately, there's no golden standard for 3D file formats. Some devices use full-width SBS, some support half-width SBS, some support MPO, and some of them support multiple of the above file formats.
The first step in getting your Lightfield files to a format viewable on your target device is to find out what file format the device supports. Then, you need to find a path to getting your Lightfield image into that format.
Because full-width SBS is so popular, there is a good chance your device supports it. In many cases, all you have to do is export your Lightfield image from LeiaPlayer into an SBS file and it will simply work on your legacy 3D device or XR headset. If not, you can often easily find 3rd party programs on your computer to turn your full-width SBS file into a half-width SBS or MPO file. This makes it easy to get your favorite Lightfield images onto your other devices.

You should expect to use a 3rd party software tool like after the fact to rectify and align the images. You should create files in an SBS or Quad Lightfield format for viewing on Lume Pad. High disparity images made this way will look much better viewed in Stereo View Mode (ST) instead of Lightfield View Mode.
Purpose-built stereo 3D cameras have a wide range of potential quality, even within units of the same model. While there are many different models, we recommend the for photos if you can find it. High disparity images shot on stereo 3D cameras will look much better viewed in Stereo View Mode (ST) instead of Lightfield View Mode.
iOS devices use a mix of software and hardware to capture superior depth in their Portrait Mode pictures. These Portrait Mode images are fully supported by Leia software. Please read for more information.

This generally isn't recommended if you have alternative options, but one method that can work well with practice is the Cha-Cha Method, which uses a single camera and a quick motion from the photographer to move weight from one foot to the other to capture a stereo image. Any movement in the scene between shots will make for a bad image. But it can work in a pinch! And if the Cha-Cha itself didn't work to produce a good 3D image, you can take one of the images and convert it to 3D, as described below.
You can use the to render out a Quad Lightfield image in Maya.
If all of the above are true, you can simply take two or more photos in a horizontal line from within the game's Photo Mode and stitch them together into an SBS using a 3rd party app like from Google Play.
You can actually capture 3D images from almost any PC game using a 3rd party tool that gains access to the graphics engine's depth buffer like Try these tools yourself to experiment and see the best ways to capture 3D images inside your favorite PC games.

The best way to share Lightfield images to other Leia devices is to your account on ! LeiaPix is already the place where everyone is sharing and talking about the best Lightfield images on the platform. If you want to show off your images, LeiaPix is definitely the place to do it.
There are broadly two ways to share Lightfield images to a 2D device: as a LIF or as a Lightfield Animation. If you share a LIF to a 2D device, it will simply look and work like a normal JPG! No additional work required. Lightfield Animations however are a way for people on 2D devices to get a sense of the depth of the image without a Leia device. To learn more about Lightfield Animations, go to the page.
In most cases, editing Lightfield video for Lume Pad is largely the same as editing 2D video. However, there are some caveats.
One major consideration is that Lume Pad has a 16:10 ratio. If you'd like to make use of full screen on Lume Pad, you may want to create a 16:10 video. However, 16:9 and wider ratios will play on Lume Pad with horizontal black bars above and below your content, or the user can double-tap the screen in LeiaPlayer and have the video fill their screen.
There are three kinds of video you can edit into Lightfield video that can play on Lume Pad:
2D Video
3D SBS Video
Quad Lightfield Video
For 2D video, you have one major consideration which will affect decisions you make: will you want to keep the output in 2D and have it converted on-the-fly in LeiaPlayer? Or will you want to convert the finished product (or the original clips) into Quad Lightfield using Lightfield Studio?
If you wish to play it back on Lume Pad using Instant 2D to 3D conversion in LeiaPlayer, then the process is identical to editing a regular 2D video.
If you wish to adjust the depth of the conversion, make manual edits to the Lightfield views, or use the 2D clips as part of a larger Lightfield video, then you must first do as much editing as you can to the 2D video until the clips look the way you want, then use Lightfield Studio's 2D Content Conversion to convert the files into Quad Lightfield. To learn more about 2D Content Conversion, visit the Lightfield Studio Documentation.
Working in SBS is the recommended method for creating Lightfield video on Lume Pad. Users will be able to play the content back in both Stereo 3D View Mode and have it automatically converted on-the-fly in Lightfield View Mode if they wish as well.
Luckily, most major NLE's fully support 3D SBS video. These include:
Once you have your SBS master of your video, you can either use it as-is everywhere in the Leia ecosystem, or use Lightfield Studio to convert from SBS to Quad Lightfield for specific mastering for Lume Pad. To learn more about Lightfield Studio's Stereo Content Conversion feature, go to the Lightfield Studio Documentation.
Currently, there is no tool to edit Lightfield native video such as Quad Lightfield. Though you can string Quad Lightfield video together in any NLE (video editing app), none of the tools in the apps are aware of the Lightfield format's structure, which limits what you can do with it. Due to this, we currently only recommend converting to Quad Lightfield as one of the last steps of your editing process if you choose to use it. In most cases, creators should probably work in SBS instead.
Everything you need to know about Lightfield videos on Leia devices.
There are three major ways to create Lightfield video:
Shoot video with a camera
Render video using a software tool
Capture video inside real-time software
You can use a variety of 2D and 3D cameras to create Lightfield videos. We'll list them here from highest potential for quality to lowest.
The best way to capture Lightfield 3D video is to build a custom stereo rig using two or more high-quality cinema cameras. Doing this is difficult, but can yield the highest quality results. The distance between the sensors, the accuracy of the synchronization, the precision of the calibration, and of course the quality of the sensors and optics all play a part in the quality of the outcome.
You should expect to use a 3rd party software tool to stitch, synchronize, and align the images. You should edit the two videos into a single SBS file for viewing on Lume Pad or editing. High disparity SBS video made in this way will look much better viewed in Stereo View Mode (ST) instead of Lightfield View Mode.
Purpose-built stereo 3D cameras have a wide range of potential quality, even within units of the same model. While there are many different models, we recommend the Sony HDR-TD Series Camcorders for 3D video if you can find it. For subjects you're shooting from a closer distance, the RED Hydrogen One is also considered one of the best 3D video cameras available today. High disparity images shot on stereo 3D cameras will look much better viewed in Stereo View Mode (ST) instead of Lightfield View Mode.
One of the best ways to create Lightfield video is with LeiaCam, which shoots SBS video on the Lume Pad.
You can also use a variety of normal cameras to shoot 2D video to convert to Lightfield later. Your smartphone, a DSLR, a mirrorless camera, or even a cinema camera can all be used. You can even use a webcam!
You can either convert from 2D to Lightfield in real-time in the LeiaPlayer app, or you can convert a professinal Lightfield video in Lightfield Studio.
There are a variety of software tools that let you render out a stereo 3D or Lightfield video.
You can use the Leia Maya Plugin to render out a Quad Lightfield video in Maya.
Some creators compose Quad Lightfield and SBS videos in other apps using custom camera configurations.
There are plugins that allow you to render your game scene in SBS and Quad, and you can use that to render a Lightfield video. Leia's SDKs for Unreal Engine and Unity can be used for this to render Quad Lightfield video.
You can also capture 3D video from inside some of your favorite real-time apps or games on Windows PC.
You can actually capture 3D videos from many popular PC games using a 3rd party tool that gains access to the graphics engine's depth buffer like SuperDepth3D. Try these tools yourself to experiment and see the best ways to capture 3D videos inside your favorite PC games. SuperDepth3D supports over 100 of the most popular AAA PC games of all time. Here is SuperDepth3D's game compatibility list.
There are three major ways to view Lightfield video on Lume Pad:
LeiaPlayer: For local video files
LeiaTube: For video streams from YouTube, Twitch, and other services
LeiaFlix: For renting Hollywood movies in 3D
LeiaTube is a service that lets you take an online video stream from your favorite platforms like YouTube, Twitch, Vimeo, DailyMotion, and more and have them automatically convert to Lightfield 3D. You can use 2D video streams, SBS 3D video streams, and even VR180/360 video streams.
LeiaFlix makes it easy to rent high-quality Hollywood movies on the Lume Pad. Simply make a LeiaFlix account, add a payment method, and voila! You can easily rent a huge variety of movies from studios like Warner Bros. and Universal.
Sharing Lightfield Video is easy! You can simply send the SBS or Quad Lightfield file to the other person using any communication platform that supports sending video and it will be able to be played back on the recipient's Lume Pad.
If you just want to share your video with Lume Pad users, you can upload your video to . To learn more, go to LeiaStream.com.
To identify which apps are Lightfield and which are not, look at their app icon on your Android Home Screen or App Drawer. Lightfield apps have a white glow around their app icon. In additioin, in the default Lume Pad theme, Lightfield apps appear above all other Android apps in the App Drawer if it's enabled.
