Back in July of 1985, Michiel van de Panne published a BASIC version of a
fractal landscape program in Creative Computing. Subsequently, Jim Cathey
coded a version of the fractal landscape program for the Mac in C.
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?
