Deep-learning the Latent Space of Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We suggest a method to directly deep-learn light transport, i. e., the mapping from a 3D geometry-illumination-material configuration to a shaded 2D image. While many previous learning methods have employed 2D convolutional ... -
Learned Fitting of Spatially Varying BRDFs
(The Eurographics Association and John Wiley & Sons Ltd., 2019)The use of spatially varying reflectance models (SVBRDF) is the state of the art in physically based rendering and the ultimate goal is to acquire them from real world samples. Recently several promising deep learning ... -
Global Illumination Shadow Layers
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Computer graphics artists often resort to compositing to rework light effects in a synthetic image without requiring a new render. Shadows are primary subjects of artistic manipulation as they carry important stylistic ... -
Tessellated Shading Streaming
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Presenting high-fidelity 3D content on compact portable devices with low computational power is challenging. Smartphones, tablets and head-mounted displays (HMDs) suffer from thermal and battery-life constraints and thus ... -
Combining Point and Line Samples for Direct Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We develop a unified framework for combining point and line samples in direct lighting calculations. While line samples have proven beneficial in a variety of rendering contexts, their application in direct lighting has ... -
Distributing Monte Carlo Errors as a Blue Noise in Screen Space by Permuting Pixel Seeds Between Frames
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Recent work has shown that distributing Monte Carlo errors as a blue noise in screen space improves the perceptual quality of rendered images. However, obtaining such distributions remains an open problem with high sample ... -
Orthogonal Array Sampling for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We generalize N-rooks, jittered, and (correlated) multi-jittered sampling to higher dimensions by importing and improving upon a class of techniques called orthogonal arrays from the statistics literature. Renderers typically ... -
Adaptive BRDF-Oriented Multiple Importance Sampling of Many Lights
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Many-light rendering is becoming more common and important as rendering goes into the next level of complexity. However, to calculate the illumination under many lights, state of the art algorithms are still far from ... -
Quantifying the Error of Light Transport Algorithms
(The Eurographics Association and John Wiley & Sons Ltd., 2019)This paper proposes a new methodology for measuring the error of unbiased physically based rendering algorithms. The current state of the art includes mean squared error (MSE) based metrics and visual comparisons of ... -
Analytic Spectral Integration of Birefringence-Induced Iridescence
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Optical phenomena that are only observable in optically anisotropic materials are generally ignored in the computer graphics. However, such optical effects are not restricted to exotic materials and can also be observed ... -
Wide Gamut Spectral Upsampling with Fluorescence
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Physically based spectral rendering has become increasingly important in recent years. However, asset textures in such systems are usually still drawn or acquired as RGB tristimulus values. While a number of RGB to spectrum ... -
Real-time Image-based Lighting of Microfacet BRDFs with Varying Iridescence
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Iridescence is a natural phenomenon that is perceived as gradual color changes, depending on the view and illumination direction. Prominent examples are the colors seen in oil films and soap bubbles. Unfortunately, iridescent ... -
Adaptive Temporal Sampling for Volumetric Path Tracing of Medical Data
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Monte-Carlo path tracing techniques can generate stunning visualizations of medical volumetric data. In a clinical context, such renderings turned out to be valuable for communication, education, and diagnosis. Because a ... -
Scalable Virtual Ray Lights Rendering for Participating Media
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Virtual ray lights (VRL) are a powerful representation for multiple-scattered light transport in volumetric participating media. While efficient Monte Carlo estimators can importance sample the contribution of a VRL along ... -
Ray Classification for Accelerated BVH Traversal
(The Eurographics Association and John Wiley & Sons Ltd., 2019)For ray tracing based methods, traversing a hierarchical acceleration data structure takes up a substantial portion of the total rendering time. We propose an additional data structure which cuts off large parts of the ... -
Microfacet Model Regularization for Robust Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Today, Monte Carlo light transport algorithms are used in many applications to render realistic images. Depending on the complexity of the used methods, several light effects can or cannot be found by the sampling process. ... -
Glint Rendering based on a Multiple-Scattering Patch BRDF
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Rendering materials such as metallic paints, scratched metals and rough plastics requires glint integrators that can capture all micro-specular highlights falling into a pixel footprint, faithfully replicating surface ... -
On-Site Example-Based Material Appearance Acquisition
(The Eurographics Association and John Wiley & Sons Ltd., 2019)We present a novel example-based material appearance modeling method suitable for rapid digital content creation. Our method only requires a single HDR photograph of a homogeneous isotropic dielectric exemplar object under ... -
Flexible SVBRDF Capture with a Multi-Image Deep Network
(The Eurographics Association and John Wiley & Sons Ltd., 2019)Empowered by deep learning, recent methods for material capture can estimate a spatially-varying reflectance from a single photograph. Such lightweight capture is in stark contrast with the tens or hundreds of pictures ... -
