Class Fractal

  • All Implemented Interfaces:
    java.awt.event.ActionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, javax.swing.RootPaneContainer
    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, the c 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 varibles z and c. 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 contain z and c as well as itts the number of itts before divergence maxItts the maximum number of itterations specifed. This value is set in a field in the main window. For example if(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.

    For details on the how the thread are implement see the FractalCanvas class. See main thread documentation.
