GradientColoring:Standard_Smooth

Object version of Smooth in Standard.ucl. This coloring method provides smooth iteration colors for Mandelbrot and other z^2 formula types (Phoenix, Julia). Results on other types may be unpredictable, but might be interesting. Thanks to Linas Vepstas for the math. Originally written by Damien M. Jones

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)
