Abstract
The focus point in Mixed Reality applications is the merging of objects from different realities into a new, visibly homogeneous scene. To achieve this, next to a spatial registration, a plausible illumination of the objects is required. While shadows and direct illumination can deliver a realistic look to the objects, adding indirect interaction of illumination will result in a seamless integration of objects, to appear as part of the scene instead of glued-on patches. Mixed Relality systems find appliance in entertainment areas like movies and games, as well as prototype presentations or visualization of planned or damaged constructions. We propose an algorithm based on Voxel Cone Tracing to provide Global Illumination for Mixed Reality that enables diffuse as well as specular lighting and easy to compute soft-shadows.
