Interactive Visualization and Analysis of Transitional Flow
Found in: IEEE Transactions on Visualization and Computer Graphics
By Gregory P. Johnson,, Victor M. Calo, Kelly P. Gaither
Issue Date:November 2008
pp. 1420-1427
A stand-alone visualization application has been developed by a multi-disciplinary, collaborative team with the sole purpose of creating an interactive exploration environment allowing turbulent flow researchers to experiment and validate hypotheses using ...
Hardware-Assisted Feature Analysis and Visualization of Procedurally Encoded Multifield Volumetric Data
Found in: IEEE Computer Graphics and Applications
By Manfred Weiler, Ralf Botchen, Simon Stegmaier, Thomas Ertl, Jingshu Huang, Yun Jang, David S. Ebert, Kelly P. Gaither
Issue Date:September 2005
pp. 72-81
Procedural encoding of scattered and unstructured scalar datasets using radial basis functions (RBFs) is an active area of research with great potential for compactly representing large data sets. This reduced storage requirement lets the compressed data s...
Feature-Driven Data Exploration for Volumetric Rendering
Found in: IEEE Transactions on Visualization and Computer Graphics
By Insoo Woo,Ross Maciejewski,Kelly P. Gaither,David S. Ebert
Issue Date:October 2012
pp. 1731-1743
We have developed an intuitive method to semiautomatically explore volumetric data in a focus-region-guided or value-driven way using a user-defined ray through the 3D volume and contour lines in the region of interest. After selecting a point of interest ...
Visual Analytics for Finding Critical Structures in Massive Time-Varying Turbulent-Flow Simulations
Found in: IEEE Computer Graphics and Applications
By Kelly P. Gaither,Hank Childs,Karl W. Schulz,Cyrus Harrison,William Barth,Diego Donzis,Pui-Kuen Yeung
Issue Date:July 2012
pp. 34-45
Visualization and data analysis are crucial in analyzing and understanding a turbulent-flow simulation of size 4,096³ cells per time slice (68 billion cells) and 17 time slices (one trillion total cells). The visualization techniques used ...
Ray tracing and volume rendering large molecular data on multi-core and many-core architectures
Found in: Proceedings of the 8th International Workshop on Ultrascale Visualization (UltraVis '13)
By Aaron Knoll, Kelly P. Gaither, Michael E. Papka, Paul A. Navrátil, Ingo Wald
Issue Date:November 2013
pp. 1-8
Visualizing large molecular data requires efficient means of rendering millions of data elements that combine glyphs, geometry and volumetric techniques. The geometric and volumetric loads challenge traditional rasterization-based vis methods. Ray casting ...
