This library generates reflective spectral power distribution curves for spectrum-based rendering in POV-Ray without recourse to a spectrophotometer. The user submits a color specification, and a spline is returned. Some of the curves are designed to resemble reflection spectra of typical non-metallic surfaces.
The user can then convert the splines to POV-Ray’s native RGBFT format using other tools, such as Lightsys IV or SpectralRender. (If the Lightsys link doesn’t work, here is an alternative download site.)
This project is a proposed module for the Persistence of Vision Raytracer (POV-Ray) Object Collection.
