Rendering Point Clouds

[NicoBux]

Hi,

Does PyTorch3D support differentiable rendering of point clouds? That is, .ply or .obj files with only vertices data and no faces.

Thank you!

Yes, we support rendering pointclouds. Check out this tutorial https://github.com/facebookresearch/pytorch3d/blob/master/docs/tutorials/render_colored_points.ipynb

And yes you can store data with pointclouds in .ply format by only providing verts

Great thank you! I'm not sure how I missed that tutorial, it's exactly what I needed. Although, I'm not sure why load_ply() enforces the presence of faces in the .ply. Since mine doesn't have any, I had to load it with Open3D and manually create the Pointcloud object (similar to the above tutorial).

Anyways, thanks for the prompt response and well-documented library. That definitely helps separate it from the rest
