it'll be slow...  no doubt about it...  if you're planning it do it
in screen mode 19 (which i hope you are) then you can speed up the
graphics output a whole lot by writing directly to memory...

screen mode 19 uses linear memory (i.e. the pixel one to the right of
another will follow IMMEDIATELY after it)...  so...  i'd write a
little routine like this:

procedure s19_pixel(sequence pos,integer colour)
   -- where pos is {x,y}
   poke(#A0000 + 320 * pos[2] + pos[1],colour)
end procedure

anyway...  for the actual 3d engine...  i'd check some of the 3d
tutorials at:
ftp://x2ftp.oulu.fi (i don't know the exact directory)
ftp://ftp.cdrom.com/.3/demos/code review
