LeiaViewer
Interact with 3D models on your device or from Sketchfab in a powerful and flexible 3D Lightfield model viewer.
LeiaViewer is your home for viewing and enhancing 3D models in an immersive Lightfield environment. You can precisely tune the depth and appearance of your model and create dynamic backgrounds for a pleasant viewing and content creation experience. You can also log in to SketchFab to search and view millions of 3D models.
Home Screen
- Your home screen will display all of the models opened on your device, whether they are stored locally on your device or stored in temporary storage via the SketchFab explorer

Depth Slider
- The slider on the left side of the UI controls the disparity value
- As you move the slider up, the depth effect of the model will increase
Lightfield / 2D Switch
- By default the Lightfield view will be enabled, so that you can see the model in 3D
- Tap the 2D button to view the model in regular 2D
- Note that in 2D mode, the depth slider will not appear in the UI
Animations

If you have issues loading a Sketchfab model, please send us the following:
- Name of model and author
- Describe the problem (is it a crash, is there an error modal, did the model fail to load?)
- Describe visual issues (does the model look different than model thumbnail image?)
- Is the center of rotation correct
Environment Adjustments
Light
- The brightness slider increase the intensity of the light shined onto the model
- Rotation X slider moves the location of the light on the X axis
- Rotation Y slider moves the location of the light source on the Y axis
- Color selector adjusts the color of the models background
- Increasing the brightness slider will increase the saturation of the colors selected
Effects
- The DOF (Depth of Field) slider takes into account how much depth is in the scene and adds a blur.
- Any object in the scene that has too high of a disparity value will be blurred
- Move the slider to the right to increase the blur effect
- This blur helps fix cross-talk issues. When objects have too much depth added to them and are not in focus, the blur helps conceal the visual issues
- The Bloom slider adjusts how the light sources hit the object
- Move the Bloom slider to the right to give the object a stronger “glow”
Materials
- The materials section allows you to select different material designs for your model
- Includes Metal, Carbon and Wireframe materials
Undo/Redo
- Tap the left facing icon to undo any change made in any of the Adjustment categories
- Tap the right facing icon to redo any changes undone in any of the adjustment categories
- Tap the Restart circle icon to bring your model back to its original appearance before you made any changes in the Adjustment categories
