Hi, When I sample points(use commends the function utils/data_pre_util.py/get_sampling_command provide),

pointnet-master/utils/third_party/mesh_sampling/build/pcsample ../data/my_data/veg.txt ../data/my_data/veg.ply -n_samples 2048 -leaf_size 0.005000

it occurs error like this, pointnet-master/utils/third_party/mesh_sampling/build/pcsample: No such file or directory

so can I get the file third_party/mesh_sampling/build/pcsample.

Thanks in advance.

Which code are you using for sampling 1024 points? I couldn't find the program for this in the repo.

The binary is not present in the master. I assume there is a binary coded using PCL (c++). We also use PCL to process PCD data (lidar points). The flags are for c++ command line parser.

The mesh sampling is done in PCL
