Lighting
The Lighting coloring algorithm interprets results from one of the Slope fractal formulas to create fractals with 3D lighting effects. It will probably not give very good results with other fractal formulas.
See Slope (Julia, Mandelbrot, Newton) for more information.
Lighting is available as a coloring algorithm in Standard.ucl and as a coloring plug-in in Standard.ulb.
