Summary
Submitted by Monte Carlos on 7 July 2011
The Program can calculate fractal images based on a 3x3 pattern recursively drawn on the screen. The executable is called just "3x3frac". The D64 is intended for transfer to the C64, the .zip with the single files in it for use with Vice. Just drag the executable "3x3frac" into the Vice Window to start. The .3x3 files are patterns which can be used as a base for fractal generation. To understand how the program works use the easymode (under options) with patternsize of 81 and x/y repeats equal to one and try different patterns. The .ini file holds the options so that you can save your parameters. You can draw several fractals over each other to get more complicated designs (Look into the example .jpgs). If you want to save your several steps store the options and rename the .ini file after each step.
There is a undo function. After each time drawing is started, a backup of the bitmap is being made.
With undo you can return to this stage loosing the most recent changes.
Because the program has many possibilities i built in an easy and an expert mode. The easymode lets you just choose the patternsize and the number of repeats in x and y. The pattern is always being centered. There are predefined values which can be choosen. In expert mode you can adjust more parameters and there are no predefined values. Therefore some parameter combinations may return unexpected results. This way your creativity is not limited but you will need some more time to get what you want.

I started to write a doc file in german, but i have too less time to continue with it at the moment. So, please contact me via email, if you have questions. Anyway, i think most functions will explain itself.

CSDb (Commodore 64 Scene Database) is a website which goal is to gather as much information and material about the scene around the commodore 64 computer - the worlds most popular home computer throughout time. Here you can find almost anything which was ever made for the commodore 64, and more is being added every day. As this website is scene related, you can mostly find demos, music and graphics made by the people who made the scene (the sceners), but you can also find a lot of the old classic games here.
