Re: OpenGL question....

["Brian Holley" <comp_brain@hotmail.com>]

Hey-

It seems to be that you wouldn't need to isolate those matrices to be able 
to do that.

All you would have to do is draw you scene normally (zooming away), then 
push that matrix onto the stack, translate (zoom) to where you want to draw 
the object, draw it there and then either pop your original matrix to 
continue drawing the scene or load the identity into the modelview matrix.

Did that make sense, or am I not quite grasping what you want to do here?
