The latest version doesn't have the function "point cloud to SDF"

I want to generate SDF (Signed Distance Function) from a point cloud. I can't find this function in the latest version, while version 0.1 has the function sdf_ = kal.conversions.pointcloud_to_trianglemesh(points).

I wonder how to generate the SDF with the latest version.

Hi @yang-si-hang , thank you for your interest in Kaolin.

You are asking to generate an SDF from a point cloud but the function you quoting here is a point cloud to trianglemesh function, can you specify what do you want?

If you look at the underlying code in https://github.com/NVIDIAGameWorks/kaolin/blob/v0.1/kaolin/conversions/pointcloudconversions.py#L68-L77 you will find that the functions rely on a voxelgrid conversion at intermediate step, which may or may not something that you want in your conversion. It should be pretty easy to reproduce in the latest version.
