CGAL users discussion list

Hello,

I'm trying to use the functions of the package Polygon_mesh_processing to extract a closed, manifold mesh from a set of unorganized polygons. I'm following the example in Polygon_mesh_processing/polygon_soup_example.cpp . However, already a first call to orient_polygon_soup() - which returns true - does not modify the orientation of any polygon, although by visual inspection I can clearly see that many faces are not oriented consistently. The mesh resulting from polygon_soup_to_polygon_mesh() is not closed, even after a call to stitch_borders(). At this point, triangulating the mesh with triangulate_faces() produces a non valid mesh (i.e., CGAL::is_valid() returns false).

I'm attaching a .ply with the input polygon soup. Any pointer is highly appreciated!

Thanks,

Claudio
