ABSTRACT

In the previous chapters, all the main notions about n-Gmaps and n-maps have been defined, and also related data structures and algorithms. However, only the combinatorial aspects have been studied corresponding to the structure (or topology) of the associated subdivisions. But the combinatorial description is not sufficient for many applications. It is often needed to associate different information to cells. For example a material (resp. a color, a length) can be associated with each volume (resp. each face, each edge) of a 3D object.
