Changelog
The key new features in this release is support for Implicit/Volume Rendering. This includes several methods for sampling camera rays and marching along the rays in order to render their color. We further introduce support for voxel grids. To this end, we implemented a new Volumes
structure and methods for converting between Pointclouds
and Volumes
. The rendering of implicit surfaces as well as voxel grids has been showcased in two new tutorial jupyter notebooks.
We are also introducing a new projects folder with an implementation of NeRF. We plan to add more examples of papers which can be implemented using components from PyTorch3D.

Builds
- For Linux, instead of uploading wheels to PyPI which will only work with one particular version of PyTorch and CUDA, we now provide a range of built wheels on S3. Refer to INSTALL.md for instructions on how to download and install.
