FLAM3 Color Shifting
Here's a new experimental
FLAM3 feature: color shifting. In these four images the parameter is
set from 0 (original, normal, unshifted) to 0.001, 0.01, and 0.04.
Without color shifting this
sheep, by Chris Ursitti, cannot be adjusted to use more of the
palette. It is inherently almost monochrome because one of its xforms
dominates in weight. So the color coordinate converges, and you get
monochrome. But if you reduce the weight, the shape is ruined. The
color shifter recognizes convergence and breaks it by shifting the
palette as long as the coordinate remains fixed.This hack is only a
few lines of code in flam3.c and is checked into CVS.
