SuGaR SO slow in calculating the foreground mesh!

I've been calculating here for hours and hours and it's not over. I use 16 vCPU Intel(R) Xeon(R) Platinum 8481C and RTX 4090D(24GB) * 1.

Hello @sunm1206 ,

Indeed, this is surprising as computing the mesh should only take a few minutes. Your GPU has a lot of VRAM, so the problem should not be your GPU memory.

It appears that the problem comes from the Poisson Surface reconstruction implementation from Open3D; I noticed myself that the Poisson surface reconstruction of Open3D is CPU-heavy and may take much more time if the CPU is intensively used by other programs at the same time. Depending on the programs I use in parallel, the Poisson reconstruction can go from 5 minutes to 30 minutes on my computer (the difference is huge!). Could you try rerunning the script and reduce the load on the CPU when performing the mesh extraction?

I'm currently investigating other mesh extraction methods (implemented for GPUs) and will try to propose a replacement for Poisson in the coming weeks.

I've encountered same situation with you. Have you solved this problem? I've used varies devices but all got stuck here.
