Maybe interesting for programmers

I found this:

http://3dfractals.com/

a software that explores tetrabrot fractal.
Maybe's useful for implements new forumulas on mb3d?
Inside a lots of documents!!!

Do you know the pure formula itself? Btw, it's already plenty of "brots" and nobody uses them!

It looks as some kind of generalisation. Actualy I think it is mandelbrot in XY axis and cubic formula by quadratic generalisation in YZ axis posted here: http://www.fractalforums.com/mandelbulb-3d/first-post-something-fundamental-about-fractal-generation-t11008/

Maybe you don't use brots..
I think it's too much interesting explore all type of fractals...
But, here I post this only for whom want, maybe, implement other formulas in mdb3d...

There are two guy, who can implement, Jesse and Darkbeam

I don't use MB3D much but I bet it is already implemented as a hypercomplex variety. The formula is (sorry for the GLSL)
z=vec4(z.x*z.x-z.y*z.y-z.z*z.z+z.w*z.w,2.0*(z.x*z.y-z.z*z.w),2.0*(z.x*z.z-z.y*z.w),2.0*(z.x*z.w+z.y*z.z))+c;//tetrabrot
It is a 4D mandelbrot using bi-complex numbers.

My favorite varient is this...
z=vec4(z.x*z.x-z.y*z.y-z.z*z.z+z.w*z.w,-2.0*(z.x*z.y-z.z*z.w),-2.0*(z.x*z.z-z.y*z.w),2.0*(z.x*z.w+z.y*z.z))+c;//eiffel
