parallelization of surface reconstruction (ball pivoting) #2968

Open mjaein opened 3 years ago

mjaein commented 3 years ago

The surface reconstruction algorithms, (ball pivoting for example) get slow for large point clouds. They seem to be not parallelized.

Using OpenMP to use more cores and speed up the meshing.

Poisson reconstruction is quite parallel, you should give it a try http://www.open3d.org/docs/latest/tutorial/Advanced/surface_reconstruction.html

Thanks for the reply. It seems that poisson reconstruction (Kazhdan's Code) is actually parallel. I was looking at SurfaceReconstructionBallPivoting implementation. If I understood it correctly, it is not using openmp.
