Surface reconstruction from point clouds #121

Open IgnacioEG opened 4 years ago

IgnacioEG commented 4 years ago

Hello,

I would like to know if the algorithms of surface reconstruction from point clouds that are available at CGAL are also available from pygalmesh.

I have been looking for examples but I have not found any.

Regards

This is principally impossible. Points clouds are not enough information to reconstruct a geometry. You can construct the convex hull of a point cloud with tools like qhull though.

I am not asking if it is possible or not. I am asking if the routines that are already implemented in GDAL can be used in python via pygalmesh https://cgal.geometryfactory.com/CGAL/doc/master/Manual/tuto_reconstruction.html

Ah, I get it. No, those are not interfaced in pygalmesh.
