With the implementation of my Mandelbrot and Julia Set fragment shaders and a Raymarcher at my disposal it was obvious that I had to do some 3D/4D fractals. As a first shot I experimented with a 3D Mandelbrot surface function formula suggested by Bugman: x=x^2-y^2-z^2 y=2xy z=2xz-2yz. Source as always on Github: GL3_Raymarcher_Mandelbrot3D.java and the corresponding fragment shader: .fs
