Subsample a point cloud

[Marco_geo]

Hi, I have a point cloud of 7654345 points. I have to do a semplification between points of 5 cm, 10 cm and 50 cm. When I makes a subsample of 50 cm I can not generate a mesh and The PC bloks. WHY?

Thanks a lot

Marco

Are you using Delaunay or Poisson Reconstruction?

Can you share the point cloud with me?

I'm using a Poisson recostruction beacause the mine pillar is in 3D. Yes, i Can but how can I send you the file .txt?
ps:sorry but I'm new in this forum

If it's not too big, simply send it to cloudcompare @ danielgm.net

Okay, in the end it appeared that it was an issue with PoissonRecon 7 (it could crash on very small clouds). I've updated the plugin with PoissonRecon 8 and it seems to fix this issue.

Thanks for the feedback.
