3D SFBM
From Ultrafractal Wiki
3D SFBM is a Coloring Algorithm in sam.ucl.
What is it?
This coloring uses the same technique as the "Slope" formulas to give a "3d" view of the fBm algorithm. It is designed, like S.F.B.M. Pixel, to be used with "Pixel" in mt.ufm.
Parameters
Phi/Theta
To determine where the light come from. Phi is the azimuth of the light source and theta its elevation.
All the other parameters are the same as those from S.F.B.M. Pixel.
