Reverse subdiv and polyhedron_3 <-> Triangulation_3 conversions?

Xiaofan Li-2

Hi all,

 

I am (still) new to CGAL and would like to know the followings:

 

a) Given a Polyhedron_3 mesh, how to make an even coarser mesh out of it? That’s about losing details intentionally, as opposed to the subdiv method introduced in the tutorial.

 

b) Given a Polyhedron_3 mesh (made by polygon facets), is there a way to convert it to a Triangulation_3 using tetrahedrons?

 

Any hints are extremely welcome.

 

Regards,

Xiaofan
