This Panel divided in four principal sections:

The Light Distribution control

Defines how the Diffuse light will be mapped over the surface of the fractal.
The options are:

Standard: The distribution of the diffuse light is calculated in the standard way.
Sine Stripes: The distribution of the diffuse light is perturbed by a sine wave.
Cosine Stripes: The distribution of the diffuse light is perturbed by a cosine wave.
Exponential: The light intensity is calculated by using an exponential function
Random: The light intensity is perturbed by an small random value
Interference: The distribution of the diffuse light calculated by an interference pattern.
Soft Light: The light intensity is evenly distributed over the surface of the fractal.
