- BUG Sometimes according to normal-map or/and vertex normals, combined with micro-facets distribution, reflected ray must go below the surface. This is currently rendered as black. Should probably do something smarter in that case.
- BUG Debug coordinates are wrong when canvas is scaled down
- hitting bvh with triangles is too slow. Need more efficient in-memory structure after loading gltf. Grid patches could be faster
- when sampling skybox, sample normal-oriented hemisphere, not entire sphere
- configuration UI
- work stealing
- scene creation progress ui
- vec4 for bitangents
- figure out Jacobians, need better comments in PDFs and reflection part of PBR
- glTF
- loading progress
- combine factors with textures
- transmission
- volume, ior
- compute mikktspace in app
- strided attributes
