1. A method of modeling hyperspectral images, the method comprising: building a scene in a first frame with objects and materials using a three dimensional modeling tool, selecting at least one hyperspectral band, changing the reflectivity of each object and material in the scene to correspond to reflectivity in the at least one hyperspectral band, changing the emissivity of at least one spectral source for each object and material in the scene to correspond to the emissivity of the at least one spectral source in the at least one hyperspectral band, rendering the scene to generate a hyperspectral image, and repeating for subsequent frames.
