// POV-Ray spectral rendering example
//
// This renders the GretagMacbeth(tm) ColorChecker Color Rendition Chart.
// Like the old one I do actually own.
//
// Useful as reference for the usage of the diffuse colors available within the
// "spectral-materials" include file.
//
// The DeltaE (for the L*a*b values using CIE 1994 graphic art and CIE 2000) of the
// spectral render compared to the reference values from the GretagMacbeth data
// sheet is less than 1.0 for all color patches, so the accuracy for diffuse
// reflectance of the spectral renderer rig is really good.
