A Scalable Parallel Force-Directed Graph Layout Algorithm
(The Eurographics Association, 2008)
Understanding the structure, dynamics, and evolution of large graphs is becoming increasingly important in a variety of fields. The demand for visual tools to aid in this process is rising accordingly. Yet, many algorithms ...
End-to-End Data Reduction and Hardware Accelerated Rendering Techniques for Visualizing Time-Varying Non-uniform Grid Volume Data
(The Eurographics Association, 2005)
We present a systematic approach for direct volume rendering terascale-sized data that are time-varying, and possibly non-uniformly sampled, using only a single commodity graphics PC. Our method employs a data reduction ...
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 Study of Parallel Data Compression Using Proper Orthogonal Decomposition on the K Computer
(The Eurographics Association, 2014)
The growing power of supercomputers continues to improve scientists' ability to model larger, more sophisticated problems in science with higher accuracy. An equally important ability is to make full use of the data output ...
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 ...
Scalable Parallel Feature Extraction and Tracking for Large Time-varying 3D Volume Data
(The Eurographics Association, 2013)
Large-scale time-varying volume data sets can take terabytes to petabytes of storage space to store and process. One promising approach is to process the data in parallel, and then extract and analyze only features of ...
Cross-Node Occlusion in Sort-Last Volume Rendering
(The Eurographics Association, 2010)
In the field of parallel volume rendering, occlusion is a concept which is already widely exploited in order to improve performance. However, when one moves to larger datasets the use of parallelism becomes a necessity, ...
A Study of Transfer Function Generation for Time-Varying Volume Data
(The Eurographics Association, 2001)
The proper usage and creation of transfer functions for time-varying data sets is an often ignored problem in volume visualization. Although methods and guidelines exist for time-invariant data, little formal study for the ...
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 ...
Parallel Volume Rendering on the IBM Blue Gene/P
(The Eurographics Association, 2008)
Parallel volume rendering is implemented and tested on an IBM Blue Gene distributed-memory parallel architecture. The goal of studying the cost of parallel rendering on a new class of supercomputers such as the Blue Gene/P ...
