Detailed Description

A mesh is part of an graphical object, in which faces are made of vertices according to some rule of formation.

The mesh is the basic building block of an mesh object (MeshObject). It has a single material, and indexes to vertices that define faces according to a rule (on a triangle strip, for instance, the first 3 indexes from a face, and then each new index from a new face together with the last 2 indexes). A mesh degenerates to a single polygon if the mesh object has no pratical rule of formation.
