I brought this up once before, but the avalanche of responses quickly
overwhelmed me :-).  Here goes again...

I'm sure most people have seen games like Stellar 7, Arctic Fox, and
Elite.  While fairly simple, the graphics are nonetheless realistic 3-D.
Question is, does anybody have source/object/vague general notions of
how to do 3-D transformations in assembly language?

I have a couple of old Nibble magazines, but those requires some transcen-
dental functions and square roots (the latter of which is not well handled
in the GS toolbox... +/- 3...).  Is there a better/faster way?

On a related note, has anybody come up with a faster line drawing routine
than Applesoft hires?  If you've ever looked at the code, you'd know that
writing faster code would be difficult... understanding the code is hard
enough in itself...
