Real-time depth of field using multi-layer filtering
Kai Selgrad, Christian Reintges, Dominik Penk, Pascal Wagner, Marc Stamminger · 2015
We present a novel technique for rendering depth of field that addresses difficult overlap cases, such as close, but out-of-focus, geometry in the near-field. Such scene configurations are not managed well by state-of-the-art post-processing approaches since essential information is missing due to occlusion.
