FRACT1: Generates a fractal based on user input. Some good entries are:
x=0 y=1
y=0 x=1
x=3 y=0
The program generally takes a couple of minutes to run.
Window size is how close to the fractal you want to get. Smaller
is closer.
FRACT4: Fract4 takes the fractal algorithm used in fract1 and goes it one
better. It makes it 3 dimensional. That is, it takes the fractal
drawn in fract1, turns it ON EDGE, and plots it onto a SINGLE
SCAN LINE of the monitor. It then changes the fractal algorithm
slightly (which is what the "change value for x and y" is), and
then recalculates the fractal on the next scan line. It does
this for all 200 scan lines in lo res color. This amounts to
something like 180 million double precision floating point
calculations in less than 1/2 hour. Pretty impressive for a
lowly ST. This algorithm is similar to one that people are
using VAX 11/780s to calculate. We're working on a fractal
program to draw four dimensional dragons next.
