END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

Im al.

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.

would love to see this with a larger iteration count and smoother colors ..

hello and welcome to the forums

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....
