FRACTAL WIZARD 1.5 - ABSTRACT
! Fractal Magic -> Fractal Wizard
!
! Originally, Fractal Wizard was called Fractal Magic. Shortly after I posted
! it on Internet, I discovered that a commercial fractal-drawing program with
! the same name (and much the same features) already existed. So, to avoid any
! confusion and unpleasantness, I renamed my program Fractal Wizard and
! reposted it. If you already have my Fractal Magic, please replace it with
! this version. I made some improvements, and it is still freeware!
Fractal Wizard is a complex-plane fractal drawing program. It can generate
black and white or 8-bit colour images. The fractal-calculation code is kept
separate from the main program code, which handles displaying in windows,
saving PICT files, and other things. The fractal generators can be compiled
separately with MPW or THINK Pascal, or any other development environment that
lets you generate stand-alone code. Fractal Wizard itself will allow you to
import these generators and test and use them.
Fractal Wizard includes generators for the Mandelbrot set, Julia sets, and a
distorted Mandelbrot version. Instructions for writing your own can be found
under Help.
The standard Mandelbrot set generator is hand-hacked assembly language, using
the FPU only when magnification becomes too large for using 32-bit fixed point
numbers. Using fixed point speeds calculation up by a factor of about 3. In
that mode, it outruns any straight escape-time Mandelbrot-set drawing program
for the Mac II I've ever seen. Full help is included, and can be saved in
separate files to be printed.
Fractal Wizard requires an 68020, 68881, Colour QuickDraw, and System 6.0 or
newer. Currently, this means it will run on the SE/30 and all Mac II models,
except the IIsi. You should be able to get Fractal Wizard to run on a IIsi or
LC if you add an FPU to them, or use John M. Neil's PseudoFPU cdev.

If that fails (I don't know for how long I'll have that address), snail mail
