You're welcome and good, I wish Nick would post here for us all to learn.

Five transforms in OpenGL
Vertices pass through these three.
1) Viewing     Specifies location of camera
2) Modeling    Moves objects around the scene
3) Projection  Defines the viewing volume

4) Viewport    Maps the 2D projection to the rendering window
5) Modelview   Combination of viewing and modeling transforms

Must be executed in a specific order.
