Imagination was given to man to compensate him for what he is not, and a sense of humor was provided to console him for what he is. - Oscar Wilde

The simplest algorithm for generating a representation of the Mandelbrot set is known as the “escape time” algorithm. A repeating calculation is performed for each x, y point in the plot area and based on the behavior of that calculation, a color is chosen for that pixel.
Fractals have fascinated me for over 20 years. Back in the 80’s I had a fractal drawing program for my C-64 that could take over a day to render a relatively crude fractal image. For every day use, though, four to eight hours wasn’t unusual.
Over a decade ago I picked up a tiny screen saver that adjusts equation parameters and escape colors and redraws the screen continuously. (It can be quite mesmerizing…)
And now, just the other day I ran across this:
The Formula by Tom Beddard at subblue.com.
To create the 3 dimensional Mandelbrot set a tripartate coordinate is used (x,y,z) and, instead of a color to represent escape time, a distance calculation is used.
Even cooler than this is the name of the shape: a Mandelbulb.
I don’t understand the math much beyond the most basic equations and I don’t have the software to play with Mr Beddard’s add-ons, so I really appreciate him putting this little film together.
Check out the Gallery; there are some stunning pics in there and, if you have Photoshop CS4 you can download and play with several add-ons found on the Projects page.
