Ask HN: Simple 3D animation file format?
File formats such as FBX and USD attempt to do everything and as a result are quite complicated.
Is there a layered 3D/animation interchange format that allows for relatively painless scene interchange between 3D apps?
By layered I mean something where each feature builds on the previous features. Something like:
1) OBJ-like static geometry
2) materials and lighting
3) per-frame transform matrices
4) animation curves
5) etc.

Nice visual overview here: https://github.com/KhronosGroup/glTF/blob/main/specification/2.0/figures/gltfOverview-2.0.0b.png https://github.com/KhronosGroup/glTF/blob/main/specification...
