Modeled Animation, becomes more than a support, playing a basic role in the creation of a three-dimensional world. Man, in fact, has always found it difficult to represent three-dimensional space in drawings; few people can draw in true perspective. Furthermore, it is simply impossible to produce all the tens of thou

This process has been a common research theme since the first three-dimensional Systems; numerous algorithms have been proposed to solve the problem [Sutherland et al, 1974]. They can be classified int

This is why the first algorithms involving ray tracing carried out the process in the opposite direction R

Bratman [2] showed that these attitudes are not sufficient, and added the attitude of
