A Julia rotated on 3D space at each iteration, rendered with Fragmentarium's new brute-force raytracer: http://www.fractalforums.com/3d-fractal-generation/rendering-3d-fractals-without-distance-estimators/

It can't do large renders, but it's excelent for trying out formulas without using a distance estimator, something I always wanted to have. Also it works fast enough for interactive parameter tweaking.

Thanks Syntopia!!

Wow, that's absolutely amazing! More of this formula, please!

Thanks... I'll try to explain:

At every iteration, I take x and y coordinates as real and imaginary parts of a complex number, the same you do in 2D. I square the number as in a standard Julia, but then I apply a 3D rotation before adding julia constants. That's it.

In the last version I'm testing, the julia constants are also rotated, and I added a scaling factor that helps into finding interesting shapes.
