Question: Mandelbulb with Maple

Hi,
if you google for Mandelbulb or look at this link:

http://www.skytopia.com/project/fractal/2mandelbulb.html

you find some nice render pics. To program this in Maple, the complex number z in the "usual" mandelbrot iteration z->z^2+c needs to be replaced by... a vector from R^3 ? Or do i need quaternions ? A source for an algorithm would be welcome.  

Please Wait...
