Interactive Relighting of Virtual Objects under Environment Lighting Hasselt University
Current relighting applications often constrain one or several factors of the rendering equation to keep the rendering speed real-time. For example, visibility is often precalculated and animations are not allowed, changes in lighting are limited to simple rotation or the lighting is not very detailed. Other techniques compromise on quality and often coarsely tabulate BRDF functions. In order to solve these problems, some techniques have started ...
