mndlzoom.prg COLOR monitors ONLY (low resolution)
mndlrsc.rsc
mndlzoom.doc
Generates Mandelbrot set images, as discussed in Scientific American last
year, and numerous other places since then. Briefly, this program lets
you select and magnify portions of the Mandelbrot set, resulting in
intricate, multi-color images. The Mandelbrot set is generated by some
computation intensive mathematics, so each image is drawn rather slowly.
Depending on the amount of black in the image, and the number of
iterations, this time can range from 5 or 10 minutes to many hours(!!).
Images can be saved to disk and reloaded.
BUGS:
1) Whenever I try to save an image using the "save" option, I
get a "mushroom" crash. The "save as" option seems to work
just fine, however.
2) If you try to save a file for which there is no room on the
diskette (each file takes about 32K), the file is only
partially written, no error indication is given, and the
running program seems to be trashed in subtle ways.
It's necessary to reboot to fix the program.
3) The monitor must be in low resolution mode before the program
is run. If not, the images will be displayed garbled.
About "mndlzoom". I have the source to this program, and I'm starting
to fix the bugs and extend the functionality. (The most important
feature I want to add is to give the user a lot of control over how
the image is colored. This is the really fun part of Mandelbrot
programs.) Anyway, I'd be really interested in any bugs or comments
on the existing program. I'll upload my version when I've made some
progress on it (probably a month or two, knowing my current schedule.)
