A small release. Python 3.7 is no longer supported. We support from PyTorch 1.9.0 to PyTorch 1.13.0. [EDIT: post-release, builds for 1.13.1 have also been added.]

New feature

• Marching cubes now has an efficient CUDA implementation. https://github.com/facebookresearch/pytorch3d/commit/8b8291830e6ca1f5882700e214f114d5442a04db . Improvements to the cpu code too https://github.com/facebookresearch/pytorch3d/commit/1706eb8216248e54f68cad86f7ea4125c79a3ca4

Minor new features

• The experimental glTF support now allows writing meshes to GLB files, including with TexturesUV textures. https://github.com/facebookresearch/pytorch3d/commit/cc2840eb4408f8fd6ad0531e3a817d73e0a53e03
• Specification of param groups in implicitron made more flexible https://github.com/facebookresearch/pytorch3d/commit/7be49bf46fdce44ec41fc22d29e99d614c1988d6
• Implicitron’s loader for Co3D-style datasets can load multiple categories https://github.com/facebookresearch/pytorch3d/commit/e4a329814978934b2fda8fb92c2c14ebb42fa0b2
• Implicitron can be used without the lpips library being present. https://github.com/facebookresearch/pytorch3d/commit/322c8f2f50bb95e9d89c47126e081cb57395d116

Fixes

• Implicitron visualization https://github.com/facebookresearch/pytorch3d/commit/c3a6ab02da3192aa18cda85d66d957a11aacfa10 https://github.com/facebookresearch/pytorch3d/commit/94f321fa3dd776da5edd1efa80e8a094ee5e6b02
• Implicitron’s rasterize_mc https://github.com/facebookresearch/pytorch3d/commit/1706eb8216248e54f68cad86f7ea4125c79a3ca4
• Implicitron’s voxel grid, especially its scaffold https://github.com/facebookresearch/pytorch3d/commit/a1f2ded58a502f0d65c86ff6c86f417689a5c8d4 https://github.com/facebookresearch/pytorch3d/commit/bea84a6fcd9bf35950f32868deb9fb5b540c4534 https://github.com/facebookresearch/pytorch3d/commit/f711c4bfe9b1e3dcc968c3182bfb563dc0299893
• raysampling: The origins in a raybundle (which downstream code typically doesn’t use) were wrong when unit_directions=True https://github.com/facebookresearch/pytorch3d/commit/eff0aad15acf9125c1dae6820ae1414f783466f0
