Initialization Phase Original Light (White) Material Index of Refraction For each wavelength (color) θi Each ray from the white light will hit the refractive surface

Initialization Phase Creates New Dispersive Light Source Origin (position) Direction (θo) Color Original Light (White) θi θo Each white light ray that hits the refractive surface will be refracted in to different directions.
