CGAL users discussion list

[<>]

Hello I am a student at the university of Poitiers in Science and Mathematics
and plans to specialize in 3D visualization. Poitiers has a laboratory whose
work is quite interesting (http://www.sic.sp2mi.univ-poitiers.fr/). Under a
draft person I need to create a parser "3D L-System" with operations based on
2D and 3D objects the aim is to come to something equivalent to http://blip
.tv/file/1473837 (city of engine) so CGAL choice seemed natural. But despite 
my
careful reading of the documentation that could not answer my questions. That
is why I ask :
* Is what makes CGAL operations such extrusions?
* Does CGAL allows for Polyhedrons and especially for Nef_Polyhedrons recover
vertex and triangle indices for is to make a exporteur in any format and can
display it in geomviewer other thing?
* Does CGAL can add vertex and triangle indices (model in a modeler any) in a
Polyhedron and especially a Nef_Polyhedrons to create it and apply Boolean
operators?

Thank you in advance for your future answers.

Sincerely KHIAT Soufiane
