Mesh triangulation and simplification C++ library

Question

I am looking for a C++ library to triangulate and simplify 3D mesh. My 3D meshes are potentially huge (around 3 millions vertices). It should ideally be open source. Any idea?

Answer 1

Here are some libraries I found:

1) CGAL

++ Does a lot of things;

-- Licensing issues;

2) GTS

++ Open source and quite easy to use;

-- Does less that CGAL

anymore ideas?
