Realization of virtual photometric environment by photometric pattern projection

In this paper, we introduce the virtual photometric environment which is one of mixed reality systems. The virtual photometric environment enables arbitrary control over the lighting directions and reflection properties of objects. The environment is realized by photometric pattern projection onto screen objects. Reflection properties of the photometric patterns are acquired from real objects. As an application, a demonstration system was constructed which reproduces the reflection properties of Japanese ceramic arts on a white plaster vase with changing lighting direction.
