The code computes several example mandelbulbs, 3 dimensional analogues to 2 dimensional fractals.

mandelbulb_play_5_release computes several example mandelbulbs, which are 3 dimensional analogues to 2 dimensional fractals. Mathematical definitions of the mandelbulbs are taken from the Mandelbulb Wikipedia page, and could, in principle, be much higher dimensional objects. The code divides a region of space under consideration into voxels, and then computes whether each voxel is like to remain finite when its coordinates are plugged into a typical mandelbulb iterated equation. This is very similar in concept to, say, a 2 dimensional Julia calculation. See Wikipedia for a description of the equations and other relevant material.
The code is a subroutine with multiple arguments, including a gpu option. After the main computation, the code demonstrates changing the color and texture of the shell of the computed mandelbulb. The code listing includes a trivial historical outline of mandelbulbes and references.
