Probabilistic Marching Cubes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper we revisit the computation and visualization of equivalents to isocontours in uncertain scalar fields. We model uncertainty by discrete random fields and, in contrast to previous methods, also take arbitrary ...
Curve Density Estimates
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this work, we present a technique based on kernel density estimation for rendering smooth curves. With this approach, we produce uncluttered and expressive pictures, revealing frequency information about one, or, multiple ...
A Visual Analytics Approach for Peak-Preserving Prediction of Large Seasonal Time Series
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Time series prediction methods are used on a daily basis by analysts for making important decisions. Most of these methods use some variant of moving averages to reduce the number of data points before prediction. However, ...
A User Study of Visualization Effectiveness Using EEG and Cognitive Load
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Effectively evaluating visualization techniques is a difficult task often assessed through feedback from user studies and expert evaluations. This work presents an alternative approach to visualization evaluation in which ...
A Shader Framework for Rapid Prototyping of GPU-Based Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper, we present a rapid prototyping framework for GPU-based volume rendering. Therefore, we propose a dynamic shader pipeline based on the SuperShader concept and illustrate the design decisions. Also, important ...
Farthest-Point Optimized Point Sets with Maximized Minimum Distance
(ACM, 2011)
Efficient sampling often relies on irregular point sets that uniformly cover the sample space. We present a flexible and simple optimization strategy for such point sets. It is based on the idea of increasing the mutual ...
Complete Tensor Field Topology on 2D Triangulated Manifolds embedded in 3D
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
This paper is concerned with the extraction of the surface topology of tensor fields on 2D triangulated manifolds embedded in 3D. In scientific visualization topology is a meaningful instrument to get a hold on the structure ...
Visual Boosting in Pixel-based Visualizations
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Pixel-based visualizations have become popular, because they are capable of displaying large amounts of data and at the same time provide many details. However, pixel-based visualizations are only effective if the data set ...
Surface Patches from Unorganized Space Curves
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Recent 3D sketch tools produce networks of three-space curves that suggest the contours of shapes. The shapes may be non-manifold, closed three-dimensional, open two-dimensional, or mixed. We describe a system that ...
Real-Time Diffuse Global Illumination Using Radiance Hints
(ACM, 2011)
GPU-based interactive global illumination techniques are receiving an increasing interest from both the research and the industrial community as real-time graphics applications strive for vi-sually rich and realistic dynamic ...
