It's certainly possible, but if it goes into the TOS, it's out of my reach
and I
can't work on the 3D routines. I do have some good stuff now, and I am
currently porting a new algorithm to the Falcon which I developed for the
PC which emulates a Z-buffer without requiring a real Z-buffer. It works,
but I will soon convert it to assembler for speed. :)

That is almost certainly the best approach. It means you can optimise for
the known OpenGL supported colour depths, and then use conversion
blits to get the image into a window. If there is good VDI supported 2D
blit hardware available, then it may be accelerated too.
