Acquisition and Validation of Spectral Ground Truth Data for Predictive Rendering of Rough Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Physically based rendering uses principles of physics to model the interaction of light with matter. Even though it is possible to achieve photorealistic renderings, it often fails to be predictive. There are two major ... -
Deep Adaptive Sampling for Low Sample Count Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Recently, deep learning approaches have proven successful at removing noise from Monte Carlo (MC) rendered images at extremely low sampling rates, e.g., 1-4 samples per pixel (spp). While these methods provide dramatic ... -
Deep Painting Harmonization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Copying an element from a photo and pasting it into a painting is a challenging task. Applying photo compositing techniques in this context yields subpar results that look like a collage - and existing painterly stylization ... -
Efficient Caustic Rendering with Lightweight Photon Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Robust and efficient rendering of complex lighting effects, such as caustics, remains a challenging task. While algorithms like vertex connection and merging can render such effects robustly, their significant overhead ... -
Exploiting Repetitions for Image-Based Rendering of Facades
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Street-level imagery is now abundant but does not have sufficient capture density to be usable for Image-Based Rendering (IBR) of facades. We present a method that exploits repetitive elements in facades - such as windows ... -
Handling Fluorescence in a Uni-directional Spectral Path Tracer
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present two separate improvements to the handling of fluorescence effects in modern uni-directional spectral rendering systems. The first is the formulation of a new distance tracking scheme for fluorescent volume ... -
On-the-Fly Power-Aware Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Power saving is a prevailing concern in desktop computers and, especially, in battery-powered devices such as mobile phones. This is generating a growing demand for power-aware graphics applications that can extend battery ... -
Runtime Shader Simplification via Instant Search in Reduced Optimization Space
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Traditional automatic shader simplification simplifies shaders in an offline process, which is typically carried out in a contextoblivious manner or with the use of some example contexts, e.g., certain hardware platforms, ... -
Stratified Sampling of Projected Spherical Caps
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a method for uniformly sampling points inside the projection of a spherical cap onto a plane through the sphere's center. To achieve this, we devise two novel area-preserving mappings from the unit square to ...
