Detailed Description

MyPolygon represents a single polygon to the 3D solution display engine.

objects of this class aren't really used in the normal rendering of solutions. They are only used in the creation of the pieces display lists. Actual rendering is performed with these display lists. instances of this class are usually managed with in a Pool of objects

void MyPolygon::calcNorm ( )

calculate the normal of this polygon which is the vector pependicular to it.

this is done with some math using the polygon's vertices. if none of the vertices for a polygon that is not a line an asserion is asserted. That assertion means there is a bug somewhere.
