This paper presents a solution to the problem of using RGB data
created by most modeling systems in a spectrally-based renderer. It
differs from previous methods in that it attempts to create physically
plausible spectra for reflectances. The method searches the metamer
space for a spectrum that best fits a set of criteria. The results
are used in an algorithm that is simple and efficient enough to be
used within the rendering process for both importing models and for
texture mapping.
