Heidrich, Wolfgang2015-11-112015-11-1120001017-4656https://doi.org/10.2312/egst.20001025In recent years there has been a lot of work on interactively displaying global illumination solutions for nondiffuse environments. This is an extremely active field of research, in which a lot of different approaches have been proposed recently. In this State-of-The-Art-Report, we will discuss and compare these. This will hopefully lay the ground for systematically addressing the open questions in the future.
