sample_points_uniformly function becomes slower in cupoch

[kaixin-bai]

I test sample_points_uniformly function in both open3d and cupoch. cupoch is slower than open3d. In which kind of situations gpu could make the calculation faster than cpu?

For 50000 points:

cupoch: 0.04s
open3d: 0.002s

For 5000000 points:

cupoch: 3.5s
open3d: 0.2s

Hi @kaixin-bai ,

Thanks for your reporting!
I pushed a performance-improved sample_points_uniformly function in the master branch.
Please try it out.

I also update pypi package.
Please update the package and try it.

pip install -U cupoch
