Flow-Induced Inertial Steady Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Traditionally, vector field visualization is concerned with 2D and 3D flows. Yet, many concepts can be extended to general dynamical systems, including the higher-dimensional problem of modeling the motion of finite-sized ...
General Point Sampling with Adaptive Density and Correlations
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Analyzing and generating sampling patterns are fundamental problems for many applications in computer graphics. Ideally, point patterns should conform to the problem at hand with spatially adaptive density and correlations. ...
Decoupled Opacity Optimization for Points, Lines and Surfaces
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Displaying geometry in flow visualization is often accompanied by occlusion problems, making it difficult to perceive information that is relevant in the respective application. In a recent technique, named opacity ...
Practical Path Guiding for Efficient Light-transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a robust, unbiased technique for intelligent light-path construction in path-tracing algorithms. Inspired by existing path-guiding algorithms, our method learns an approximate representation of the scene's ...
Physically Based Video Editing
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Convincing manipulation of objects in live action videos is a difficult and often tedious task. Skilled video editors achieve this with the help of modern professional tools, but complex motions might still lack physical ...
Panoramic Video from Unstructured Camera Arrays
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
We describe an algorithm for generating panoramic video from unstructured camera arrays. Artifact-free panorama stitching is impeded by parallax between input views. Common strategies such as multi-level blending or minimum ...
