Title: New to Fractals Post by: jgschmidt on May 14, 2011, 06:42:32 PM Hi, I am new to this forum, my name is Jurgen Schmidt, from San Antonio, Texas.
I (re)discovered fractals recently, as well as the amazing capabilities of various software packages such as UltraFractal and Apophysis. I've been using these to do some random exploring but I do not understand how to find interesting regions. As I read posts on this and other forums there seem to be assumptions that I would recognize certain basic patterns and would know how or where to find them. I don't. Where can I get this basic knowledge? I've also worked with the animation features of UltraFractal to make zoom animations. These are pretty lifeless to me. Some animations I've seen animate the actual image, some of which look like swirling octopus arms or rotating gears and clockworks. Once I do find an interesting region, what kind of changes do I make to the parameters to get those kinds of results? Thanks for your help, Jurgen Title: Re: New to Fractals Post by: Erisian on May 16, 2011, 09:00:23 PM Hi. I'm no expert on fractals, but one thing I discovered recently is that a Mandelbrot is a kind of directory of Julia sets. If you zoom in on part of the edge of the brot, you can see what the Julia will look like. The most interesting julias come from the deep V between the largest and next largest parts of the brot. You can use this technique on any Mandelbrot type fractal such as Polynomials and Novas. Julia seeds are given various names depending on what software you are using, but try the following seeds on a straight Mandelbrot.
cx or x or real -0.78 cy or y or imaginary 0.13 Have fun! :howdy: Title: Re: New to Fractals Post by: jgschmidt on May 16, 2011, 10:05:11 PM Thanks, I'll give that a try.

Quote I discovered recently is that a Mandelbrot is a kind of directory of Julia sets a hint to that: ultrafractal has a so called switch mode, wher you can easily explore the mandelbrot set for related julia sets just by moving the mouse cursor over the mandelbrot area. this works for many fractal types of the built in or public formulas. just press F1 (help) in UF to get infos about that switch mode. good luck and greets taurus |
