Hello and thank you for the impressive work on CGAL.

I'm beginning with the library and trying to use the Surface_mesher example.
What I want to do is to get positions and indices to feed VBOs that I can
display with glDrawArray.

Thanks to this post
(http://cgal-discuss.949826.n4.nabble.com/Need-to-write-facets-created-from-Implicit-surface-meshing-td951670.html)
I'm able to get the vertices of the Complex_2_in_triangulation_3 and display
them (nice skull !).

But my indices array seems uncorrect and the resulting displayed triangles
are disordered.
Is there a simple example code to build VBOs adn draw them ?

And how to access normals in the result if they are performed ?

Thank you and sorry for my bad english.

BenoƮt
