Decoupled Shading for Real-time Heterogeneous Volume Illumination
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Existing real-time volume rendering techniques which support global illumination are limited in modeling distinct realistic appearances for classified volume data, which is a desired capability in many fields of study for ...
A Tri-Space Visualization Interface for Analyzing Time-Varying Multivariate Volume Data
(The Eurographics Association, 2007)
The dataset generated by a large-scale numerical simulation may include thousands of timesteps and hundreds of variables describing different aspects of the modeled physical phenomena. In order to analyze and understand ...
Semantic-Preserving Word Clouds by Seam Carving
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Word clouds are proliferating on the Internet and have received much attention in visual analytics. Although word clouds can help users understand the major content of a document collection quickly, their ability to visually ...
High-Quality Lighting and Efficient Pre-Integration for Volume Rendering
(The Eurographics Association, 2004)
Pre-integrated volume rendering is an effective technique for generating high-quality visualizations. The precomputed lookup tables used by this method are slow to compute and can not include truly pre-integrated lighting ...
A Cluster-Space Visual Interface for Arbitrary Dimensional Classification of Volume Data
(The Eurographics Association, 2004)
In volume visualization, users typically specify transfer functions to classify the data and assign visual attributes to each material class. Higher-dimensional classification makes it easier to differentiate material ...
High-Quality Rendering of Compressed Volume Data Formats
(The Eurographics Association, 2005)
Rendering directly from packed or compressed volume data formats using graphics hardware has advantages in terms of memory consumption and bandwidth, but results in lower-quality images due to the prohibitive cost of ...
Evaluating the Effectiveness of Tree Visualization Systems for Knowledge Discovery
(The Eurographics Association, 2006)
User studies, evaluations, and comparisons of tree visualization systems have so far focused on questions that can readily be answered by simple, automated queries without needing visualization. Studies are lacking on the ...
Natural Visualizations
(The Eurographics Association, 2006)
This paper demonstrates the prevalence of a shared characteristic between visualizations and images of nature. We have analyzed visualization competitions and user studies of visualizations and found that the more preferred, ...
Path Visualization for Adjacency Matrices
(The Eurographics Association, 2007)
For displaying a dense graph, an adjacency matrix is superior than a node-link diagram because it is more compact and free of visual clutter. A node-link diagram, however, is far better for the task of path finding because ...
Simultaneous Classification of Time-Varying Volume Data Based on the Time Histogram
(The Eurographics Association, 2006)
An important challenge in the application of direct volume rendering to time-varying data is the specification of transfer functions for all time steps. Very little research has been devoted to this problem, however. To ...
