software for molecular modeling and manipulation of 3d images

[BUG at campus.swarthmore.EDU]

Dear Subscribers,
   We are starting to model small molecules and crystals and need to
know how to efficiently use our Z-buffer to manipulate the images as
quickly as possible.  Has anyone ordered the "Release Tape #1 for the 4D"
which contains source code for graphics routines and has it helped you
to learn how to manipulate images efficiently.  In particular, we would
like to manipulate images using "sliders" for rotation and translation.
We would also like to store frames for quick replay.  We have 8MB of
memory and a 4D/70 GE.
