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 ...
