I think what Chambers meant is have you tried using a pigment-related function
in SDL.  You can use a custom function as your pigment pattern, and it can take
an x,y,z point (or x,y,z,t,a,b,c,...) and spit out a value to be used with a
color map.  This value is a float, not a vector, but you could have variation
of your function for each channel.

Then, there are also pigment functions, in which you can specify an x,y,z
coordinate, and a the color vector associated with that coordinate is returned.

Can you describe what the desired end result is?
