About fractal'sA fractal is some structure that, when one zooms in, indefinitely repeats itself. For instance the crystalline snowflake or the branches of a tree. Lots of natural structures have more or less the same appearance as fractals. Since it only takes little code to create complex structures fractals have become quite popular in computer generated graphics. For instance the famous program FractInt or Lapre's LParser.

How it works (for the mathematically inclined).This particular fractal (mandelbrot set) is calculated as follows the:
Now this number is multiplied by itself until
Now we take the number of iterations and assign a color to it. In my applet the lower the number of iterations the darker the pixel. Or to put it in other words less dynamic give brighter pixels. However for pixels where the number of iterations exceeds a predefined value no color is assigned in some browser that means black and in other white (yeap, that is not right, I should color them white). |

ManualIf you press the start button in the picture, the mandelbrot fractal renderer control window will appear. Here are some instructions how to use it. It is best to first start with the default number in the control window. You might want to adjust the size of the window though. After you are ready press the "start render" button. A new window should popup, which renders the selected area. You can now:
When you select an area in a render window with your mouse the values are automatically updated in the control window. When pressing the button labeled "render" in the control window a new fractal will be rendered. The check box labeled "Keep Aspect Ratio" is to keep the window's height/width ratio the same as the selected area height/width ratio. |

Downloading FracHuntFracHunt is a Win95/Win98/NT4.0 application that is as easy to use as the applet above but has much more capabilities.With FracHunt you can save your rendered picture as a windows background and of Version 1.1 as a POV-Ray heightfield. It has much more coloring functions and fractal functions and comes with an extensive help. FracHunt is careware which means that you cannot pay for it by money but you have to either do something good (not for yourself) or read the enclosed small article.

FracHunt runs on Win95/Win98/NT4.0 and probably Win2000.

Frachunt Alpha (preview of how it will look in 2003) ReleaseNOTE: Discontinued download no longer available, the old version still is of courseI am currently working on a new release of frachunt that is when I am not working on my mastermint game. You might have a peek how FracHunt might look in the future.
Note that lots of things do not work or are broke even if they worked in the
stable release. One of the things more or less implemented are animations, if you really need that you could give it a try but be aware of the fact that
it is just a snapshot while I am in the middle of changing the complete program.
To create animations you have to understand that you have to specify the first frame and the last frame. Of course also the output file, number of frames and frames per second have to be specified on the animate tab.
