About the extension to point clouds

[LY1478]

Hello, authors. I saw in the paper that PFCNN can be extended to point clouds easily, but I don't know how to implement it. Can you give me some advice? Thank you very much.

Hi. The extension to point cloud requires extending the frame field computation and multi-resolution hierarchy construction to point clouds. This could be done by connecting the point cloud into a k-NN graph and applying graph simplification for hierarchy construction. You may refer to the mesh based computation in the pySurfaceHierarchy part, as here a mesh is nothing more than a graph of points. The extension is conceptually simple but may need some coding.

Thanks for your advice, I will try it.
