class 
GradientColoring:Standard_Emboss

Object version of Emboss in Standard.ucl. Coloring algorithm for the Embossed family of fractal types. This coloring algorithm performs 3D lighting for these fractals. Uses 3 colors from the gradient, at index values of 0.2, 0.5 and 0.8. With Color Density set to 1, Transfer Function set to Linear, and Gradient Offset set to 0, these index values corresponding to the gradient positions 80, 200 and 320.

ResultIndex

public float ResultIndex(complex pz)

Description copied from class: GradientColoring

Produce a resulting color index after a sequence is finished

This corresponds to the final: section in a coloring formula. Once it is called, no further calls to Iterate() should be made without calling Init() first.

Overrides:

ResultIndex in class GradientColoring

Returns:

the gradient index (corresponding to #index in a coloring formula)
