The open source Titan Informatics Toolkit Project, which extends the Visualization Toolkit (VTK) to include information visualization capabilities, is being developed by Sandia National Laboratories in collaboration with Kitware. The VAST Contest provided ...
 
Compatible Triangulations of Spatial Decompositions
Found in: Visualization Conference, IEEE
By William J. Schroeder, Berk Geveci, Mathieu Malaterre
Issue Date:October 2004
pp. 211-218
We describe a general algorithm to produce compatible 3D triangulations from spatial decompositions. Such triangulations match edges and faces across spatial cell boundaries, solving several problems in graphics and visualization including the crack proble...
 
Large-Scale Data Visualization Using Parallel Data Streaming
Found in: IEEE Computer Graphics and Applications
By James Ahrens, Kristi Brislawn, Ken Martin, Berk Geveci, C. Charles Law, Michael Papka
Issue Date:July 2001
pp. 34-41
Effective large-scale data visualization remains an important challenge with analysis codes already producing terabyte results on clusters with thousands of processors. Frequently the analysis codes produce distributed data and consume a significant portio...
 
Verifying Scientific Simulations via Comparative and Quantitative Visualization
Found in: IEEE Computer Graphics and Applications
By James Ahrens,Katrin Heitmann,Mark Petersen,Jonathan Woodring,Sean Williams,Patricia Fasel,Christine Ahrens, Chung-Hsing Hsu,Berk Geveci
Issue Date:November 2010
pp. 16-28
This article presents a visualization-assisted process that verifies scientific-simulation codes. Code verification is necessary because scientists require accurate predictions to interpret data confidently. This verification process integrates iterative h...
 
A model for optimizing file access patterns using spatio-temporal parallelism
Found in: Proceedings of the 8th International Workshop on Ultrascale Visualization (UltraVis '13)
By Aashish Chaudhary, Berk Geveci, Galen M. Shipman, Ross Miller, Andrew Bauer, Boonthanome Nouanesengsy, Dean N. Williams, James Ahrens, John Patchett
Issue Date:November 2013
pp. 1-8
For many years now, I/O read time has been recognized as the primary bottleneck for parallel visualization and analysis of large-scale data. In this paper, we introduce a model that can estimate the read time for a file stored in a parallel filesystem when...
     
On-demand unstructured mesh translation for reducing memory pressure during in situ analysis
Found in: Proceedings of the 8th International Workshop on Ultrascale Visualization (UltraVis '13)
By Berk Geveci, Jonathan Woodring, Tom Peterka, James Ahrens, Timothy J. Tautges, Venkatram Vishwanath
Issue Date:November 2013
pp. 1-8
When coupling two different mesh-based codes, for example with in situ analytics, the typical strategy is to explicitly copy data (deep copy) from one implementation to another, doing translation in the process. This is necessary because codes usually do n...
     
A classification of scientific visualization algorithms for massive threading
Found in: Proceedings of the 8th International Workshop on Ultrascale Visualization (UltraVis '13)
By Kenneth Moreland, Kwan-Liu Ma, Berk Geveci, Robert Maynard
Issue Date:November 2013
