LeiaViewer
Interact with 3D models displayed as a 3D Lightfield
LeiaViewer is your home for viewing and enhancing 3D models in an immersive Lightfield environment. Precisely tune the depth and appearance of your model and create dynamic backgrounds, for a pleasant viewing and content creation experience. Users can also login to SketchFab to search and view millions of models.
LeiaViewer comes preinstalled on all Lume Pad devices. All future updates will be delivered via Leia Appstore on Lume Pad devices.
LeiaViewer supports the following file types:
•FBX
•OBJ
• STL
•GLB
•GLTF
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 Image size down to 4K or less in Photoshop. Object orientation and positioning - This was also adjusted in Blender.
Recommend upper limit for facecounts: 100k
Recommend upper limit for file sizes: 50MB
Recommend upper limit for textures? Over 4K definitely won't work
How should users report bugs? what kind of bugs do we want them to report to us?
If there is problem loading SF model, we need the following information:
- 1.Name of model and author
- 2.Describe problem (crash? error modal? model didn't load? progress bar frozen?)
- 3.Describe visual problems (does model look different than model thumbnail image?)
- 4.Center of rotation (is the model not centered properly?)
If there is problem loading model on device:
- 1.Send us model
- 2.Describe problem (crash? error modal? model didn't load? progress bar frozen?)
- 3.Center of rotation (is the model not centered properly?)
The file size limitations are impacted by the number of triangles, polygons and vertices of each model.
General recommendations:
- Keep polygon and vertex count below 1 million
- There is no exact limitation for opening models in viewer, it depends on the content. Try different LODs and see which works for you.
- Our rule of thumb is 100k vertices or below, max texture size at 4K
•To import models, tap the + button in the top left corner to open the file browser. Select the model files from whichever directory they are saved to 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. Load the model by clicking on it in the file browser.
