I would like to add custom attributes for point cloud, how to use Python in open3D implementation ,thanks!

The Tensor geometry classes in o3d.t.geometry have support for custom attributes.

import open3d as o3d
import numpy as np
pcd = o3d.t.geometry.PointCloud()
pcd.point.positions = np.random.rand(100,3)
pcd.point.myattr = np.random.rand(100,1)
