A JavaBrot is a picture rendered in Java using the Mandelbrot
function Z = Z^2 + c. My friend Joe Davisson wrote
a mandelbrot generating program in C that calculates parts of
the image and uses it to help estimate the rest of the image in
order to make things go faster. I took his code and converted
it over to Java, and this was the result.
||The real coordinate for the center of the JavaBrot.
||The imaginary coordinate for the center of the JavaBrot.
Use this and real center to pin point the center on the complex plane that
you would like to look for fractals.
||How many iterations to do before kicking out.
The higher the number, the nicer the brot and more you can zoom in.
The lower the number, the faster it will render.
|inc. count %:
||Every time you click, you can force the count value to
go up by a certain percent. This will get you better
zooms, but will slow the process down. It uses this
new count=old count + (old count * inc count / 100)
so a value of 0 for inccount will make count stay the same
||MandelBrot defines this as 2. If the Z in the iterations formula
gets past 2, you are supposed to kick out and color it black. We
allow you to break this rule if you want. A higher value will slow
it down and probably not change the picture much.
||Zoom simply changes the radius by this formula:
new radius = old radius / zoom.
||Radius is how much of the complex plane you are viewing. If
this is a small value, it will show you deeper in the mandel
brot (zooming you in).
||Watch the Mandelbrot as it's being generated.
||This will get all the current values from JavaBrot and put
them in the applicable text boxes.
||Reset all the boxes back to presets and re-render.
