public class Fractal extends javax.swing.JApplet implements java.awt.event.ActionListener
Applet/Application which calculates fractiles using a multi threaded system. The formula define the fractile uses complex numbers the default is z =z^2 + c
, thec
value is given by the coordinates of the individual pixels, and the color depends on the number of iterations it takes before the value diverges. The equation of the fractile can be changed, but must only use the variblesz
andc
. The formula for colors can also be changed. The default is[ (itts % 10)/10 ,( itts % 100)/100, (itts % maxItts)/ maxItts ]
the result of evaluation should be a vector with three item which values between 0 and 1. The formula for colors can containz
andc
as well asitts
the number of itts before divergencemaxItts
the maximum number of itterations specifed. This value is set in a field in the main window. For exampleif(itts==maxItts, [0,0,0], [ (re(z) + 4)/8, (4-re(z))/8, (im(z)+4)/8] )
colors by the position of z after the itteration, or black if it did not converge.The default region shown is (-2,-2) .. (2,2). Double clicking zooms in centered on the mouse position, right clicking zooms out, and dragging the mouse shifts the domain.
