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 ...
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 ...
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 ...
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 ...
An Interactive Volume Visualization System for Transient Flow Analysis
(The Eurographics Association, 2003)
This paper describes the design and performance of an interactive visualization system developed specifically for improved understanding of time-varying volume data from thermal flow simulations for vehicle cabin and ...
The Design and Evaluation of a Pipelined Image Compositing Device for Massively Parallel Volume Rendering
(The Eurographics Association, 2003)
An experimental study of software image compositing that we have carried out on a 512-node PC cluster shows the necessity of hardware compositing support to make possible real-time volume visualization scalable with large ...
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 ...
