This is called back face culling. When you define a polygon, by default,
you only show one side of it - it is not a 2 sided object. The side that
is shown, is the one where the normal points away from the surface. The
other side is not shown.
To have both sides showing, you need to tell the class to use both
sides. This can be done by setting CULL_NONE in PolygonAttributes.
