Illuminating the mixed reality stage: applying complex lighting conditions to AR

The Mixed Reality Stage is an augmented reality environment which aims to support creative and collaborative stage design processes. In this application scenario, the proper simulation of real lighting is crucial for a seamless integration of virtual objects into a physical model stage. The authors present their approach to emulating complex real world lighting conditions for rendering in real-time. They introduce mechanisms that significantly reduce the effective number of light sources, while simultaneously minimizing the loss of visualization quality
