In this paper, we describe the evolutions of SE-RAY-IR. The first evolution concerns an improvement in the description of physical materials using a BRDF model which describes complex materials (from user defined analytical models to measured data sets). The second improvement concerns the rendering algorithm. We propose a highly configurable hybrid approach which takes the best suited method for each simulated phenomena among a set of literature rendering methods. Then our hybrid approach benefits from their respective advantages. It enables the computation of highly realistic simulation of outdoor scenes, taking into account sky light multiple reflections, extended sources and glossy reflections.
