Some items in partnet-mobility have no point cloud files and point cloud labels #146

Hi, I am planning to train a point cloud part segmentation model, but I notice some of objects have no point cloud file in the partnet mobility dataset. Where can I get the point cloud files and labels?

The PartNet-Mobility dataset does not provide any point cloud files. This is a dataset providing articulated models in the URDF format. If you would like to render partial point cloud, you can follow the tutorial here https://sapien.ucsd.edu/docs/latest/tutorial/rendering/camera.html

If you want to get the full point cloud (sampled from meshes), you probably should use an alternative mesh processing library.
