Guys

A couple of things would finish my app off nicely and I could do with a few pointers as to how to implement them

See http://www.cadfem.com/ogl8.gif

1. The text at the bottom LH corner is static as is the colour bar on the RHS (they are both in the OGL render window).

Both of these items do not rotate when rotatef/scale is called AND you can move the polygon model behind the colour bar + text so that it appears behind the objects.

- you can see the model behind the text ---- kind of like an XOR opp has been performed.

2. The XYZ axis rotates as per the model BUT it has its own local origin. I.E it always stays put even if a scale/translate opp is performed.

Any quick pointers on what to look at in the Red book?

Many thanks and have a great weekend
