My Question

Assuming that we have a point cloud A with shape (N, 3) and a point cloud B with shape (M, 3), how can we judge if these two point clouds have an intersection by using the functions supported by Open3D quickly. "No intersection" means all points of point cloud A are not in the mesh constructed by the point cloud B here (It is not a point cloud registration problem). Thank you very much.
