This mainly involves FPS in point cloud processing, as well as kernel density estimation. This code repository primarily focuses on certain functionalities of the 'pointnet2_ops_lib' operator, providing methods for function calls and implementation within the PyTorch framework.
Added a feature pts_cnt
to record the number of neighboring points within the spherical radius of the current query point in 'pointnet2_ops_lib\pointnet2_ops_ext-src\src\ball_query.cpp'.
