buddhabrot

[taj]

I've never seen anyone use this in a demo of any kind yet its begging for it. Basically this is the mandelbrot set but the colour of a pixel is decided in an unusual way. Some rekigious people are going nuts over it.

Get a load of the second image with the heart in it!

The problem is by naive methods (ones that fit into small intros like 4k) it would take many minutes to compute, however just last month on 17th Septembersomeone found a way to accelerate it so its now demo speeds (ie precalc would be minimal and you can now even zoom like in a normal mandelbrot).

Its very difficult to accelerate this using pixel shaders (unlike normal mandelbrot) but a good asm coder could kick ass with this. If I write some C code, I'll post it here.

Cool as hell huh?

BTW, I'm adding these as useful like but maybe they arent. Is it appropriate for me to put links like this here admins? Maths stuff I mean.

That thing look outstanding and I could really imagine this fx in a cool moody demo.

Thanks a lot for those great links ... never heard about it before !

2 QB coders I know did buddhabrot.  One of them is Antoni.

I should be clearer, I've never seen a buddhabrot in any party entry (I usually check 256b,4k,64k and a selection of "demos"). It means unlike mandelbrot it is not yet mainstream "demo" though obviously some people have written code to render it.
