Hi David,
What is the equation between x, y and z? This is a typical problem of
curve-fitting. You must know z's highest and lowest values (even if they
are +/- infinities), which will correspond to 1 and 0 values of R; and 0 and
1 for B; G will always be 0. Also z's values will be directly proportional
to Blue and inversely proportional to Red. G will remain 0 throughout. I
think that's all about the idea.
Regards,
Biswajit
