Image Based Shadowing in Real-Time Augmented Reality
Peter Supan, Ines Stuppacher, Michael Haller · International Journal of Virtual Reality · 2006
This work presents an approach to render appropriate shadows with Image Based Lighting in Augmented Reality applications. To approximate the result of environment lighting and shadowing, the system uses a dome of shadow casting light sources. The color of each shadow is determined by the area of the environment behind the casting light source. As a result it is possible that changes in the lighting conditions immidiately affect the shadow casting of virtual objects on real objects
