Accurate refraction, thanks to raytracing, has always been a popular effect in computer graphics imagery. However, its use has been severely hindered in interactive rendering due to the lack of efficient and realistic techniques geared toward polygon oriented rendering. In this paper, a method to achieve realistic and interactive refractive effects through complex static geometry is proposed. It relies on an offline step where many light paths through the object are pre-evaluated. Duringdoi:10.1145/1111411.1111438 dblp:conf/si3d/GenevauxLD06 fatcat:oqjsexd2tvbvpom3sxyjkk6xsq
