Is there any way to extract pointcloud differentiable from sdf-based method like neus? #300

Hello, I am curious if there is a method available to extract the point cloud in a differentiable manner from trained neus model or any other sdf-based method, as the marching cubes algorithm is not inherently differentiable.
