Improvement of global illumination methods for infrared rendering of outdoor scenes including targets

ITMBS 2008-1

In this paper, we describe the recent evolutions of SE-RAY-IR that concerns improvements, firstly, of the physical materials description using a BRDF well fitted to complex materials and secondly of the rendering algorithm. We present a new highly configurable hybrid approach that takes the best-suited methods for each simulated phenomena among a set of literature rendering methods. It enables to compute highly realistic simulation of outdoor scenes, taking into account skylight multiple reflections, extended sources and glossy reflections.
