CGAL users discussion list

Hi,

You cannot really remove cells, since the triangulation must have the 
topology of the 3D sphere (in 4D).
But, as in the 2D package, you can mark some cells as 'deleted' if you 
like.
Look at the manual of CGAL::Triangulation_cell_base_with_info_3, and the 
user manual too.
