Cubemap-based Ambient Occlusion for Character Animation

Simulating lighting is one of the most important parts of rendering 3D scenes. While lighting coming directly from a light source is easy to simulate in real-time, indirect illumination is more difficult. One of the methods used to convincingly approximate indirect illumination is ambient occlusion, where the brightness of objects is reduced...

Ambient Light Caching via Approximate Photon Mapping

Indirect illumination is an essential part of realistic computer-generated imagery. However, accurate calculation of indirect illumination comes at high compute costs. To this end, we replace lengthy indirect illumination paths by employing an ambient light cache based on photon mapping principles. By only performing cache queries after a...

Multiple viewpoint rendering by exploiting image coherence in epipolar space

In recent years, there has been a widespread increase in the adoption of virtual reality and 3d displays which require many images as input, e.g. head mounted displays or lightfield displays. Real-time rendered imagery for such displays is commonly computed using brute-force rendering pipelines based on forward(+) or deferred rendering pipelines...
