Re: [Compgeom-discuss] help.



Hi,

Sorry for my late answer...

There are fully dynamic 3D regular triangulations in CGAL (also known as weighted Delaunay triangulations).

The class CGAL::Regular_triangulation_3 is templated by a "traits class" parameter, where you can provide your own basic objects and predicates, so, you should be able to give your own distance through the power_test predicate. However, the algorithms implicitely assume that the distance function 'looks like' the weighted Euclidean distance in R^3. I am not sure this is what you mean by "any distance function"...

Have a look at
www.cgal.org
manual (online or ps or pdf)
Chapter 3D triangulations

Best regards,
	Monique Teillaud

Hello,

I am trying to find an available software in the Internet that computes 3D weighted voronoi diagram --- one that would take any distance function as input.

Thank you for any help.
