I have known the method to achieve the goal using mesh. I want to use Pytorch3D to get point cloud's rendering normal map. The file of point cloud just has information of vertices but no faces.

There is a method for this in the file https://github.com/facebookresearch/pytorch3d/blob/main/pytorch3d/ops/points_normals.py .
