Datasets for testing TinyUSDZ

[syoyo]

We need various USDZ(USDA, USDC, USDZ) files to test TinyUSDZ.

Here is a publicly available USD(Z) resources

• https://sketchfab.com/
• https://developer.apple.com/augmented-reality/quick-look/
• https://www.intel.com/content/www/us/en/developer/topic-technology/graphics-research/samples.html
  • NOTE: Animated Knight Rigged character model is actually timeSampled data in USD format(no usdSkel). Also its usda file is corrupted.

Optional

Moana dataset is for VFX and does not fit TinyUSDZ's purpose, but may be worth to utilize it for stress testing.

ALab is also for VFX, but may be worth to utilize it for testing.

Generate manually

Blender 3.4 supports exporting USD data at nice degree. (Biggest missing feature is proper usdSkel export/import?)

Many (most?) of the Polyhaven models have .exr textures, possibly useful for testing

Note: depending on the reader's implementation, may need to flip UVs and normals (winding order) for these models
