NAME

SYNOPSIS

[-fps]

DESCRIPTION

It uses ifs {w0 = sqrt(x-c), w1 = -sqrt(x-c)} with random iteration to plot the julia set, and sinusoidially varied parameters for the set, and plots parameters with a circle.

One thing to note is that count is the depth of the search tree, so the number of points computed is (2^count)-1. I use 8 or 9 on a dx266 and it looks okay. The sinusoidal variation of the parameter might not be as interesting as it could, but it still gives an idea of the effect of the parameter.

Dragging the mouse in the window uses the mouse's position as the control point for the generation of ths set.
