GLOBAL ILLUMINATION IN INHOMOGENEOUS MEDIA BASED ON CURVED PHOTON MAPPING

摘要

This paper deals with representing several of the phenomena that occur when light travels a curved path through inhomogeneous media, such as the well-known mirages. Traditional curved ray tracing presents several problems which have not been efficiently solved yet. We present here our approach based both on curved ray tracing and photon mapping, introducing the concept of curved photon mapping.
