CloudCompare forum

Hello everyone,

is it possible with CloudCompare to crop a Digital Surface Model with a 3D cylinder in intersection?
I have a point cloud in .Las format (my Digital Surface Model) and a 3D cylinder composed of facets in .Ply format and I would like to extract the DSM points just contained in my cylinder.

Is there an option to perform this action?

Thank you in advance for your help.

Yes, you just need to compute the distances between the point cloud and the cylinder (mesh). See https://www.cloudcompare.org/doc/wiki/i ... h_Distance

Then you can select the points with negative distances (should be inside the cylinder) with https://www.cloudcompare.org/doc/wiki/i ... r_by_Value

Thank you very much for your answer.

This is exactly what I needed and it works great.
