My advice is: don't worry about the calculations.  The calculations are
easy and relatively fast.  It's the rendering that takes all the time.

That is, there's nothing wrong with putting extras in, and they can help,
but you're talking about 10% issues.  A multiply routine may or may not
help, depending on how fast it is and how much data transfer is involved.
Rotation routines -- routines to update rotation matrices, routines to
apply them to a vector -- could be useful.  Add a projection routine to
that, and you've got a very fast 3D calculator.

But are you sure you want to get into that?  Feature creep has a way of
dooming projects.

P.S. A chunky display will make your card useless for anything beyond
     static graphics, on a C64.
