Initialization Phase
Material• Index of Refraction
For each wavelength (color)
Original Light(White)
θi
Each ray from the white light will hit the refractive surface
Initialization PhaseCreates New Dispersive Light Source• Origin (position)• Direction (θo)• Color

Each white light ray that hits the refractive surface will be refracted in to different directions.
