Concept 3.2e : Drawing Triangles in 3D Space
=============================================

Idea:
=====
OpenGL provides GL_TRIANGLES to render 
triangles.

GL_TRIANGLES :
Draws a series of triangles using vertices V0,
V1, and V2, then V3, V4, V5 and so on.  If n 
is not an exact multiple of 3, the final one
or two vertices are ignored.

Experiment:
===========
Can you specify the vertices to specify a 
pizza with six equal slices and having its 
center at the origin?
