Detailed Description

HalfEdge objects are used in the process of polygon subdivision in MyObject::subdivide().

For every subdivision iteration performed, a complete half-edge model is generated for the polygon mesh. a half-edge is a tupple of an edge of a polygon and one of the vertices it touces.
