How does OpenGL calculate the mipmap scale factor ( particularly the size of polygon to be textured ) and is there a way to get access to this value? Thanks!

Not quite sure what you're asking for, but most questions like "How does OpenGL..." are answered in the API specification. Maybe section 3.8.8 will help you? It describes more of an ideal implementation of OpenGL, where real implementation are allowed to deviate to a certain degree for practical reasons.

Thats ok you pointed me in the right direction ;) i was racking my brain searching the redbook for that stuff.

Thanks for the link...for the record what i wanted was the scale factor algorithm for a polygon, cheers!
