This release brings new targets and many improvements.

Builds for PyTorch 1.10.1, 1.10.2, 1.11.0, but no longer 1.6.0. Builds for Python 3.10 but no longer 3.6.

New Features

  • MultinomialRaysampler and NDCMultinomialRaysampler replace GridRaysampler and NDCGridRaysampler commit which can sample using the new n_rays input and also bring stratified sampling along rays and direction normalization (also commit
  • Function join_cameras_as_batch commit
  • Function join_pointclouds_as_batch commit
  • Camera batches can be indexed commit and commit
  • Meshes.submesh function to take a set of faces from a mesh. commit and commit
  • L1 support for KNN and chamfer commit

Bug fixes

  • Rasterizer.to broken without cameras commit
  • Joining batches of meshes with TexturesAtlas and TexturesUV broke first input meshes’ texture commit
  • Transform3D.stack was entirely broken. commit which also added typing.
  • The function cameras_from_opencv_projection always created on CPU #1021 commit
  • Batching didn’t work for AmbientLights #1043 commit
  • Pointclouds.subsample failed on windows #1015 commit
  • Fit_textured_meshes tutorial now turns off perspective_correct in the final optimization, to avoid nans. commit

Improvements

  • Points_normals much faster through use of symeig workaround commit
  • A warning is now printed to console on rasterizer bin overflow commit

Small improvements

  • MeshRendererWithFragments and matrix_to_axis_angle made more importable
  • FacePointDistance, FacePointDistance and point_mesh_face_distance get min_triangle_area argument commit - default also changed in commit
  • Fix for small faces in IoU3D commit
  • Lower the epsilon value in the IoU3D commit
  • Flexible background color for point compositing commit and commit
  • In points_to_volumes, the rescaling of features is now optional. commit
  • LinearWithRepeat layer clarified and moved inside PyTorch3D from the NeRF project commit
  • HarmonicEmbedding moved inside pytorch3d from projects/nerf. commit and commit
  • Invalid default values in Meshes.init removed commit
  • Support obj files missing usemtl declarations commit
  • CamerasBase.unproject_points typing commit
  • Fix for Pointclouds.init in certain cases with None in a list commit
  • Consistency validation for sampling_mode in joining TexturesUV commit
  • Doc fix for camera space fix from v0.6.1 commit
  • Doc fix for renderer pictures commit
  • New ndc_grid_sample to handle grid-sampling using our NDC conventions commit
  • Fix scatter_ error in cubify on CPU commit
  • In Transform3D, fix some dtype inconsistencies commit
  • Fixes to make windows builds happier commit

Internal

  • Rename pytorch3d.common.types to pytorch3d.common.datatypes commit
  • Cleanup in ply_io commit
  • A major new feature, a framework for new-view synthesis via modeling neural-network based representations, called implicitron, is work in progress.
  • We now use usort not isort for sorting imports.
  • Future proofing calls to torch.meshgrid commit and symeig commit also commit. Also future proofing tests for a change to autograd behaviour that inplace operations don’t need to return the same object commit
  • Future proofing for the loss of TH headers in pytorch (needed for PyTorch 1.11) commit and commit
  • Base class for shaders introduced commit
