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 ...
Sequences with Low-Discrepancy Blue-Noise 2-D Projections
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Distributions of samples play a very important role in rendering, affecting variance, bias and aliasing in Monte-Carlo and Quasi-Monte Carlo evaluation of the rendering equation. In this paper, we propose an original sampler ...
Approximate Program Smoothing Using Mean-Variance Statistics, with Application to Procedural Shader Bandlimiting
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We introduce a general method to approximate the convolution of a program with a Gaussian kernel. This results in the program being smoothed. Our compiler framework models intermediate values in the program as random ...
A General Illumination Model for Molecular Visualization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Several visual representations have been developed over the years to visualize molecular structures, and to enable a better understanding of their underlying chemical processes. Today, the most frequently used atom-based ...
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 ...
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 ...
Learning Scene Illumination by Pairwise Photos from Rear and Front Mobile Cameras
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Illumination estimation is an essential problem in computer vision, graphics and augmented reality. In this paper, we propose a learning based method to recover low-frequency scene illumination represented as spherical ...
Gradient Outlier Removal for Gradient-Domain Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a new outlier removal technique for a gradient-domain path tracing (G-PT) that computes image gradients as well as colors. Our approach rejects gradient outliers whose estimated errors are much higher than those ...
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 ...
