Yes !


Have a look at the example voronoi_3.cpp;
When you call the function CGAL::import_from_triangulation_3, you can 
use an undocumented third parameter (a std::map 
std::map<Triangulation::Cell_handle, LCC_3::Dart_handle >) linking cells 
of the T3 and darts of the LCC.

With this map, you can know if a dart belong to the infinite vertex of 
the T3 or not.
