Hi,

  I remember there are surface reconstruction function from the point set data in CGAL. It can handle more complex model than your models. You can have a try.

Hello,

I am new to CGAL and want to solve a quite simple task. My goal is to
generate a Surface-Mesh from building data which mainly consists of
3D-points.

The source of my data is a Building Infrastructure Model so the forms I have
to mesh are quite simple. The data mainly consists of walls with holes like
windows and doors.
I have read through the manual and some postings, but I don't quite know
where to start. I have tried to generate the mesh using the
Surface_reconstruction_Points_3 example but I did not get good results
because of the sharp creases.

Another idea I had was to create Nef-polyhedrons from the vertices of a wall
and "substract" the Nef-polyhedrons I generated from the holes and then mesh
the surface of this result. Is this possible and which Kernels and Packages
would be the best ones to use?

Or is there maybe an easier way to generate the mesh?


Thank you in advance!

Best regards,
Christian
