[comp.sys.mac] Fractals...Jim Cathey where are you?!

viking@iuvax.UUCP (Jon W. Backstrom) (02/08/88)

Back in July of 1985, Jim Cathey did a C version of the fractal landscape
program written by Michiel van de Panne in BASIC and published in the July
1985 issue of Creative Computing.

Jim's program is called "Fractal Contours" and was published as a public
domain program on an EDUCOMP disk.

The major enhancements that Jim added to the program were to recode it in
C and to use "a CORDIC rotator instead of trig functions".  I want to talk
with Jim about his program....where is he?!

Alternately, does anyone know anything about "CORDIC rotators"?  I'd like to
see the source to his modification of Michiel's program.  The algorithm used
was based on one developed by LucasFilm Ltd. and published in the Sept. '84
Scientific American.

Any help is greatly appreciated.....Jim?
