Mr User Of SGI machine,
maaybe… just MAYBE you need to spend a ~little~ more time checking out the chapters in the red book on drawing images. This question, your other poster re: raster pos is all trivially answered in the red book. These questions aren’t a combination of ideas, where you might have a bug, but “atomic ideas” described in…
the
red
book
just a thought.
cheers,
John
