Skeleton based Vertex Connection Resampling for Bidirectional Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Bidirectional path tracing is known to perform poorly for the rendering of highly occluded scenes. Indeed, the connection strategy between light and eye subpaths does not take into account the visibility factor, presenting ...
General and Robust Error Estimation and Reconstruction for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Adaptive filtering techniques have proven successful in handling non-uniform noise in Monte-Carlo rendering approaches. A recent trend is to choose an optimal filter per pixel from a selection of non spatially-varying ...
Robust Statistical Pixel Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Robust statistical methods are employed to reduce the noise in Monte Carlo ray tracing. Through the use of resampling, the sample mean distribution is determined for each pixel. Because this distribution is uni-modal and ...
Rich-VPLs for Improving the Versatility of Many-Light Methods
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Many-light methods approximate the light transport in a scene by computing the direct illumination from many virtual point light sources (VPLs), and render low-noise images covering a wide range of performance and quality ...
T-SAH: Animation Optimized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We propose a method for creating a bounding volume hierarchy (BVH) that is optimized for all frames of a given animated scene. The method is based on a novel extension of surface area heuristic to temporal domain (T-SAH). ...
Manifold Next Event Estimation
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present manifold next event estimation (MNEE), a specialised technique for Monte Carlo light transport simulation to render refractive caustics by connecting surfaces to light sources (next event estimation) across ...
Improved Half Vector Space Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In this paper, we present improvements to half vector space light transport (HSLT) [KHD14], which make this approach more practical, robust for difficult input geometry, and faster. Our first contribution is the computation ...
Portal-Masked Environment Map Sampling
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We present a technique to e ciently importance sample distant, all-frequency illumination in indoor scenes. Standard environment sampling is ine cient in such cases since the distant lighting is typically only visible ...
Visualization of Particle-based Data with Transparency and Ambient Occlusion
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Particle-based simulation techniques, like the discrete element method or molecular dynamics, are widely used in many research fields. In real-time explorative visualization it is common to render the resulting data using ...
