I used Visual Studio 2010 Ultimate, C# and .NET framework 4.0 (so you must
install the .net4 framework package from MS, but most people probably already
have it if they are using windows 7/vista).

The output of the utility is currently an include file which contains the color
maps structured into a pigment map. I will be implementing warp fully, and then
the other forms of blend map next.

Last thing on the list is fixing the truly abhorrent GUI, right now it is at
best awful, at worst potentially life threatening. :p

The images in this thread use 4 textures generated from the same base image
layered on 4 spheres (diameter varies by 0.001), thus giving the effect of agate
having sub surface depth.

If you are going for true accuracy, then yes you would want a calibrated input
image, but if you simply wish to use a collection of colors which appear
together in nature on the same object, then this gets it done nicely.

It would be interesting to find some method of evaluating the colors used to
produce some function, or collection of functions, which would allow a truly 3D
texture to be made. Perhaps a project for another time.

And thanks for the compliment. :)
