Approximate Bias Compensation for Rendering Scenes with Heterogeneous Participating Media
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
In this paper we present a novel method for high-quality rendering of scenes with participating media. Our technique is based on instant radiosity, which is used to approximate indirect illumination between surfaces by ...
The State of the Art in Interactive Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The interaction of light and matter in the world surrounding us is of striking complexity and beauty. Since the very beginning of computer graphics, adequate modelling of these processes and efficient computation is an ...
Selective Inspection and Interactive Visualization of Light Transport in Virtual Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
This paper presents novel interactive visualization techniques for inspecting the global light transport in virtual scenes. First, we propose a simple extension to photon mapping to gather required lighting information. ...
Rasterized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley and Sons Ltd., 2012)
We present the rasterized bounding volume hierarchy (RBVH), a compact data structure that accelerates approximate ray casting of complex meshes and provides adjustable level of detail. During construction, we identify ...
Progressive Virtual Beam Lights
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
A recent technique that forms virtual ray lights (VRLs) from path segments in media, reduces the artifacts common to VPL approaches in participating media, however, distracting singularities still remain. We present Virtual ...
