Fast Hardware Construction and Refitting of Quantized Bounding Volume Hierarchies
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
There is recent interest in GPU architectures designed to accelerate ray tracing, especially on mobile systems with limited memory bandwidth. A promising recent approach is to store and traverse Bounding Volume Hierarchies ...
Bi-Layer Textures: a Model for Synthesis and Deformation of Composite Textures
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We propose a bi-layer representation for textures which is suitable for on-the-fly synthesis of unbounded textures from an input exemplar. The goal is to improve the variety of outputs while preserving plausible small-scale ...
Area-Preserving Parameterizations for Spherical Ellipses
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present new methods for uniformly sampling the solid angle subtended by a disk. To achieve this, we devise two novel area-preserving mappings from the unit square [0;1]2 to a spherical ellipse (i.e. the projection of ...
An Appearance Model for Textile Fibers
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Accurately modeling how light interacts with cloth is challenging, due to the volumetric nature of cloth appearance and its multiscale structure, where microstructures play a major role in the overall appearance at higher ...
Attribute-preserving Gamut Mapping of Measured BRDFs
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Reproducing the appearance of real-world materials using current printing technology is problematic. The reduced number of inks available define the printer's limited gamut, creating distortions in the printed appearance ...
Line Integration for Rendering Heterogeneous Emissive Volumes
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Emissive media are often challenging to render: in thin regions where only few scattering events occur the emission is poorly sampled, while sampling events for emission can be disadvantageous due to absorption in dense ...
Fiber-Level On-the-Fly Procedural Textiles
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Procedural textile models are compact, easy to edit, and can achieve state-of-the-art realism with fiber-level details. However, these complex models generally need to be fully instantiated (aka. realized) into 3D volumes ...
Bayesian Collaborative Denoising for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
The stochastic nature of Monte Carlo rendering algorithms inherently produces noisy images. Essentially, three approaches have been developed to solve this issue: improving the ray-tracing strategies to reduce pixel variance, ...
Stochastic Light Culling for VPLs on GGX Microsurfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
This paper introduces a real-time rendering method for single-bounce glossy caustics created by GGX microsurfaces. Our method is based on stochastic light culling of virtual point lights (VPLs), which is an unbiased culling ...
Deep Shading: Convolutional Neural Networks for Screen Space Shading
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
In computer vision, convolutional neural networks (CNNs) achieve unprecedented performance for inverse problems where RGB pixel appearance is mapped to attributes such as positions, normals or reflectance. In computer ...
