SCATMECH is an object-oriented C++ class library developed to distribute models for light scattering applications. Included in the library are models for diffuse surface scattering that predict the bidirectional reflectance distribution function (BRDF), codes for calculating scattering by isolated particles, and codes for reflection, transmission, and diffraction from gratings. Emphasis has been given to those diffuse scatter models which are physics-based and which predict the polarization properties of the scattered light. The library also includes a number of classes that may be useful for working with polarized light or the optics of thin films. The library is constructed to enable expansion of new models.
