Multi-interfaces based Refractive Rendering

Figure 1: The first three images are the comparisons between our rendering result and two interface rendering method; the fourth is the ray intersection problem; the last one is our final rendering result with caustics. We presented an multi-interfaces image based method to simulate the refraction and related light effects in real time on a normal graphic card. The multi-interfaces based representation of the re-fractor is obtained by hiring depth peeling ideas. This leads to sig-nificantly better results than two interfaces refraction where only the front and back face of the object was captured
