Which operations are parallelized in Open3D?

Hi,

I am trying to speed up some pointcloud operations (addition, crop, transform and downsampling) in my python code.

I compared the timings for these operations when I use:

  • The pre-compiled pip package from PYPI
  • A built-from-source pip package with OpenMP enabled
  • A built-from-source pip package with cuda enabled

There doesn’t seem to be any difference. Are these operations not parallel?
