Nonlinearly Weighted First-order Regression for Denoising Monte Carlo Renderings
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We address the problem of denoising Monte Carlo renderings by studying existing approaches and proposing a new algorithm that yields state-of-the-art performance on a wide range of scenes. We analyze existing approaches ... -
Efficient Ray Tracing Through Aspheric Lenses and Imperfect Bokeh Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present an efficient ray-tracing technique to render bokeh effects produced by parametric aspheric lenses. Contrary to conventional spherical lenses, aspheric lenses do generally not permit a simple closed-form solution ... -
Sparse High-degree Polynomials for Wide-angle Lenses
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Rendering with accurate camera models greatly increases realism and improves the match of synthetic imagery to real-life footage. Photographic lenses can be simulated by ray tracing, but the performance depends on the ... -
Forward Light Cuts: A Scalable Approach to Real-Time Global Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We present Forward Light Cuts, a novel approach to real-time global illumination using forward rendering techniques. We focus on unshadowed diffuse interactions for the first indirect light bounce in the context of large ... -
Product Importance Sampling for Light Transport Path Guiding
(The Eurographics Association and John Wiley & Sons Ltd., 2016)The efficiency of Monte Carlo algorithms for light transport simulation is directly related to their ability to importance-sample the product of the illumination and reflectance in the rendering equation. Since the optimal ... -
Parallel Multiple-Bounce Irradiance Caching
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Building designers rely on predictive rendering techniques to design naturally and artificially lit environments. However, despite decades of work on the correctness of global illumination rendering techniques, our ability ... -
Line Sampling for Direct Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Computing direct illumination efficiently is still a problem of major significance in computer graphics. The evaluation involves an integral over the surface areas of the light sources in the scene. Because this integral ... -
Improving the Dwivedi Sampling Scheme
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Despite recent advances in Monte Carlo rendering techniques, dense, high-albedo participating media such as wax or skin still remain a difficult problem. In such media, random walks tend to become very long, but may still ... -
A Phenomenological Model for Throughfall Rendering in Real-time
(The Eurographics Association and John Wiley & Sons Ltd., 2016)This paper aims at rendering interactive visual effects inherent to complex interactions between trees and rain in real-time in order to increase the realism of natural rainy scenes. Such a complex phenomenon involves a ... -
Solid Angle Sampling of Disk and Cylinder Lights
(The Eurographics Association and John Wiley & Sons Ltd., 2016)A new unbiased sampling approach is presented, which allows the direct illumination from disk and cylinder light sources to be sampled with a uniform probability distribution within their solid angles, as seen from each ... -
Perceptually Motivated BRDF Comparison using Single Image
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Surface reflectance of real-world materials is now widely represented by the bidirectional reflectance distribution function (BRDF) and also by spatially varying representations such as SVBRDF and the bidirectional texture ... -
Eurographics Symposium on Rendering 2016: Frontmatter

AVOCADO: Visualization of Workflow-Derived Data Provenance for Reproducible Biomedical Research
(The Eurographics Association and John Wiley & Sons Ltd., 2016)A major challenge in data-driven biomedical research lies in the collection and representation of data provenance information to ensure that findings are reproducibile. In order to communicate and reproduce multi-step ... -
From Visual Exploration to Storytelling and Back Again
(The Eurographics Association and John Wiley & Sons Ltd., 2016)The primary goal of visual data exploration tools is to enable the discovery of new insights. To justify and reproduce insights, the discovery process needs to be documented and communicated. A common approach to documenting ... -
Exploratory Visual Analysis for Animal Movement Ecology
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Movement ecologists study animals' movement to help understand their behaviours and interactions with each other and the environment. Data from GPS loggers are increasingly important for this. These data need to be processed, ... -
Composite Flow Maps
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Flow maps are widely used to provide an overview of geospatial transportation data. Existing solutions lack the support for the interactive exploration of multiple flow components at once. Flow components are given by ... -
A Visual Analytics Framework for Microblog Data Analysis at Multiple Scales of Aggregation
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Real-time microblogs can be utilized to provide situational awareness during emergency and disaster events. However, the utilization of these datasets requires the decision makers to perform their exploration and analysis ... -
Location-dependent Generalization of Road Networks Based on Equivalent Destinations
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Suppose a user located at a certain vertex in a road network wants to plan a route using a wayfinding map. The user's exact destination may be irrelevant for planning most of the route, because many destinations will be ... -
ConToVi: Multi-Party Conversation Exploration using Topic-Space Views
(The Eurographics Association and John Wiley & Sons Ltd., 2016)We introduce a novel visual analytics approach to analyze speaker behavior patterns in multi-party conversations. We propose Topic-Space Views to track the movement of speakers across the thematic landscape of a conversation. ... -
TextDNA: Visualizing Word Usage with Configurable Colorfields
(The Eurographics Association and John Wiley & Sons Ltd., 2016)Patterns of words used in different text collections can characterize interesting properties of a corpus. However, these patterns are challenging to explore as they often involve complex relationships across many words and ...
