How to prepare superpoints for custom data (xyz+RGB) without mesh #10

Thank you for the great work.

For data with only xyz and rgb, how to generate superpoints ?

In dataset/scannetv2/prepare_superpoint.py, superpoints are generated by superpoint = segmentator.segment_mesh(vertices, faces), but when mesh is not available, how to generate?
