A low cost and versatile refraction model for scan-line rendering algorithms is presented. The model is based on the theoretical optical path of a light ray through a generic lens. A Gaussian approximation is then used, together with Blinn and Newell approximation. These expressions lead to a family of approximations with a tradeoff between computational… CONTINUE READING
