Creating the Pyramid Class
The Pyramid class contains the actual vertex data for our Player graphic, which will be a 3D object
in the shape of a pyramid. The Pyramid class vertex data is contained in the PyramidVertices array
and is designed to be used with a Mesh class. (See Listing 7-7.)

{
static float[] PyramidVertices =
