I'm coding mesh simplification using edge collapse method with two different cost functions

1. The edge length and the local curvature cost formula by Stan Melax
2. Quadratic error metric QEM by Garland & Heckbert

I finished coding the the above cost functions and associated the  edge cost value  between vertex Pi all in its connected vertices  Qj  

Next,  I pick the edge with minimum edge cost, I want to collapse  it using any CGAL method that operate on  3D Polyhedron mesh.


I consulted the CGAL Manual I see these options :

1. CGAL::Euler::edge_collapse which needs  the mesh to be converted to a boost graph ( not clear how to do that )

2.  Use Surface mesh simplification package ( but how to provide to with my own cost function)

Please advise on how to proceed with edge collapse operations ?


Best Regards to CGAL-ers
