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

L1 support for KNN and chamfer commit

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.

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

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

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
