Slogro & Slogro2
By Devin Cook

                 

These two programs are implementations of the SLOGRO fractal process
described in Scientific American - Dec 1988.

Slogro.EXE is the standard implementation of SLOGRO.

Slogro2.EXE has is roughly the same process except that the main
particle movement routine has been redone in assembly ( FRAC.ASM
), and an alteration has been done to the premise, whereby
instead of the circle being a fixed radius, it is now a changing
radius, starting at 10 pixels and working its way to 100.  This
speeds things up but a factor of 20!  As the resting particles
approach the radius, the circle is backed off, as to allow for a
truly random process to still take place.

The plotter routines were written for a Comscriber plotter, but
could easily be altered to make a box on the paper at the
relative location of the particle on any plotter.

Finally the graphics are set up to run with a herc graphic card,
but it should be fairly easy to alter it to work with any
graphics system.
