Detailed Description

This file contains the meat of the ConvexPolygon implementation.

These functions are parametrized by vertex iterator type, making it possible to call them given only a fixed size vertex array. The functions which compute indexes of HTM triangles and Q3C quads intersecting a spherical region use them to avoid the cost of creating ConvexPolygon objects for each triangle/quad.
