I have been interested in fractals for years .. I started programming a mandelbrot set generator in c using sdl a couple of years back then let it go .. recently I have rewritten my code from scratch and am interested in making it more efficient. I also aim to draw julia sets .. Im pretty sure its just a small tweak in the code I have already. I really want to learn to use smooth coloring .. some of the images online are fantastic .. Im using an escape count at the moment .. Im not sure how smoothing works even though I have checked out a few web pages on it already .. its very satisfying to see the result of some labour in the beauty that exits in these fractals. http://yfrog.com/j1shot23pp (http://yfrog.com/j1shot23pp) would love to see this with a larger iteration count and smoother colors ..:P Title: Re: heya Post by: Sockratease on June 26, 2010, 07:32:22 PM Hello and Welcome to the forums!
Unfortunately, I'm not a programmer anymore (I learned by punching cards way back when I was young, then took a couple decades off of computers - missed the whole intro of Object Oriented Programming! - and never quite took to the new ways like I did years ago). But many programmers haunt these forums and will likely be along soon enough to help O0 Good Luck with your efforts.

to create a julia image out of a working mandelbrot, it is really mindblowing easy, exchange the "c" value with your "start" value! e.g. you did for mandelbrot z0=(0,0) <<- pixel pertubate z_n=z^2+c <- seed ( usually the pixel ) in julia mode you do: z0=c z_n=z^2+(0,0) <- previous pertubate, now seed for (0,0) you get a circle shape because you are just squaring a location ... which will bailout instantly....

Greetings, and Welcome to this particular Forum !!! :) Yes, programming one's own fractal generator can be very time consuming. I stopped doing so a long time ago, since there seems to be a proliferation of available applications that will never end in my lifetime. (It has become difficult to even keep up with all of them.) :) |
