Vianova......OK...here's a different rendition of my last image.

The original was 1280X960 but Photofuckit limited it to 1023X500.

As far as the basic formula goes, it's

z=z^6+c, where z and c are complex numbers such that z is initially set to a value of between (-2,-2)->(+2,+2) and c=(0,0)

Like the normal Mandelbrot set (z=z^2+c) the equation is iterated until a certain "bailout value" for z is reached. Unlike a 2D Mandelbrot set which might repeat thousands of times/pixel before bailout is reached, the Mandelbulb might only iterate 10 times before a given pixel is plotted!!! To increase the detail in the most recent rendition, I changed the bailout value from 10,000,000 to only 4!!!

The main reason I don't like the ray trace program is that it doesn't permit a color palette. The only way to affect color in the overall image is to change the lighting color falling on the image, which unfortunately affects the entire image.

I can't give you a precise value for z in the image because ChaosPro doesn't show that value in the sidebar, although it does show the value of c, which IS initially set when plotting a Julia set.
