I am interested in what facilities exist for doing advanced 3D graphics on
Sun4 and Sparc workstations. In particular, I am interested in
algebraic/parametric shaded surface display and animation. The machines
I'm working on have the cgsix graphics accelerator that uses 8 bits of
color and improves vector/polygon display speed. 

Thus, I would like to know of the following:

1) software packages for 3D graphicS

2) hardware boards/upgrades for Sun4/Sparc that improve quality and
   performance of 3D graphics, especially shaded polygon display. For
   instance, a 12 or 24-bit frame buffer would be nice. 

Mainly I'd like to know what's available now (both commercial and public
domain), but information about facilities in the making will also be
welcome.

If I get enough information, I will summarize to the net.
