If I'm not mistaken, the code for pointnet2's farthest point sampling is in "SASA\pcdet\ops\pointnet2\pointnet2_batch\pointnet2_utils.py"

There's a statement in there: from . import pointnet2_batch_cuda as pointnet2

I want to take a closer look at the code to improve my current work, but I can't find the module named point2_batch_cuda. Can you tell me where this file is? Thanks!!!

Hello, I would like to ask where is the detailed implementation code of furthest_point_sample_weights(). Looking forward to your reply!

Is there any non-cuda operations to implement the furthest_point_sample_weights? Thanks.

Hi, the detailed implementation of furthest_point_sampling_weights is in sampling_gpu.cu.

I haven't found the non-cuda implementation of the furthest point sampling algorithm and its variants. I'm afraid its non-cuda implementation is much slower than this version.

it's define in setup.py, which is build from folder('pointnet2_batch').
