Description (last modified by )
Triangulation already has a method normal_cone, which computes the normal cone of the GKZ polytope that exposes the triangulation.
What seems to be missing is a method to compute regular triangulations, given an element of the normal cone (a weight/lifting vector), computes the regular triangulation (or more generally, subdivision) of the point configuration / polyhedron.
Under some conditions, this would also make sense for polyhedral complexes.
