[net.graphics] 3d fractal generator & shader

rmc@lanl.ARPA (07/02/85)

	Addenda:

	- The fractal generation system is an
experimental one.  I believe that the shell
script 'quaternion.sh' will generate an interesting
image, but I can't guarantee what will happen
in other cases.

	- Vary the parameters (e.g., mu) and
the boolean function converges(), which computes
the iterated polynomial.  The resulting images
will vary dramatically.

	- Feel free to investigate the buffer-chaining
subsystem.  I was forced to use such a scheme under
4.1bsd on a 750; such kludges may no longer be
necessary.

	- The inspiration for my system (and the
critical boundary-tracking algorithm) came from
Alan Norton's article in SIGGRAPH '83.

	- Please keep me posted of any important
discoveries.  I'd very much like to see a real
fractal production system arise from my fragments
of code.
