I found the said documentation of Graf3D from the MPW manual (don't recall
which one).  It was better than nothing, but only briefly discussed it.  I too
had the Boxes source from Turbo Pascal.  This helped to a degree as well, but
the boxes (actually it was called BoxSphere I believe - Boxes was a simpler
program on the disk) dealt with only a limited aspect of Graf3D.
Anyway, I was going to write the game 'Elite' (or a game similar to it) for the
Mac and so I spent many months delving into Graf3D and experimenting with it. 
It worked.  It had it's limitations and was slow (by fast-paced game standards)
and so I abandoned it.  Nonetheless, I have ammassed (sp?) some amount of
knowledge of the unit.  If anyone likes, I could post a sort of tutorial of
what I'VE found out about Graf3D (if I can recall it all).

Briefly, it's fairly straightforward.  New variable types like Point3D and
GrafPort3D are defined.  The procedures allow for simple point-to-point
wireframe drawing (MoveTo3D, LineTo3D).  My biggest hurdle was becoming
familiar with the Fixed type variables it uses for angles and distance.
