Efficient Modeling of Entangled Details for Natural Scenes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Digital landscape realism often comes from the multitude of details that are hard to model such as fallen leaves, rock piles or entangled fallen branches. In this article, we present a method for augmenting natural scenes ...
Merged Multiresolution Hierarchies for Shadow Map Compression
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Multiresolution Hierarchies (MH) and Directed Acyclic Graphs (DAG) are two recent approaches for the compression of highresolution shadow information. In this paper, we introduce Merged Multiresolution Hierarchies (MMH), ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
