Detailed Description

This class stores all the information concerning hidden lines on a view.

View number
Matrix of projection
Type of projection, focal
Arrays of 3d points

A drawable shape contains a list of such objects to store the hidden lines for each view. The IsSame method is used to check if hidden lines must be recompiled.
