Documentation

User triangular meshes helper. This is the pure abstract base class from wich the user may derives a triangular mesh node. The functions BoundBox, Start(X), Next(X) are pure virtual and the user must defines it in the derived class. The functions NextVert must generate a glVertex call, the function NextFace 3 glVertex calls and the function NextEdge 2 glVertex. At the end of scanning this functions must return false. (??) Le funzioni next ritornano false a fine scansione (cioe' l'ultima scansione ritorna true, quella dopo false, insomma se ci sono tre vertici, nextvert ritorna 3 volte true e la quarta false) (??). The function BoundBox must return the bounding box of the surface.
