I looked at the 3-D routines in Nibble magazine (published about 3-4 years
ago), and was thinking about translating them into assembly on the GS (with
ample use of the toolbox routines).  When I look at some of the games available
today (Stellar 7, Arctic Fox, Elite), I know there must be a faster way of
doing it than I am considering (too many multiplications/divisions, plus a
couple of square roots).

I'd rather not get a book list (I can get one from comp.graphics, I'm sure),
but rather a fast algorithm for translating the three dimensional coordinates
into screen coords.  If anyone has used something like this (e.g., the
SubLogic package mentioned above), I'd like to know more about it.
