Prediction when inputs are point clouds #3

Hello,

Thanks for providing the source code.

I tried to use your code to segment a point cloud. I noticed that your code directly read the edge information from the '.npz' files. In your paper, you said that 'Otherwise we generate k=16 nearest neighbors from each point to form E'. So I think your code has the ability to segment a point cloud without providing 'F' in the input file, right? Can you explain how to do that?

Thanks in advance. Best. Mulin

The scene data is processed without F. knn utility is in "src/lib/knn/knn.cc".
