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)
