The first work we tried to publish was called "Differential Instant Radiosity for Mixed Reality". On this paper Christoph Traxler, Werner Purgathofer, Michael Wimmer and myself were working on a real-time global illumination rendering system for mixed reality scenarios. My master thesis already dealed with real-time global illumination by using a method called instant radiosity. It basically places virtual point lights at positions where light hits a surface.
We submitted our work to the ISMAR 2010 conference held in Seoul, South Korea and were happy to hear that it got accepted. We also presented our method on a demo booth and were very happy again about the very positive feedback of the people. However, to our total surprise, we won the "Best Paper Award" for our method - YEAH!!! :-)
Main Features:
- Real and virtual objects cast shadows onto each other
- Real and virtual objects may cause indirect illumination onto each other
- Real and virtual spot light sources are supported
- Multiple light bounces
- Real geometry must be pre-modeled
- Double shadowing artifacts may occur
- Inconsistent color bleeding may occur
