AbstractA more accurate refraction rendering algorithm, which runs entirely on GPU, is presented in this paper. The algorithm can directly render complex objects represented by polygonal meshes without any pre-calculating, and allows the objects to be deformed dynamically through the interaction of users. The rendering method allows refraction or totally internal reflection (TIR) through two or more interfaces. Our method traces the accurate paths of both refraction and TIR rays going through the transparent object, and computes the ray-surface intersection in orthogonal projection space on GPU to produce realistic image including both refraction and TIR. We also simulated the object's translucency by adopting the scattering and absorbing model in volume rendering method during the ray passing through the object.
