Enabling View-Dependent Progressive Volume Visualization on the Grid
Found in: IEEE Computer Graphics and Applications
By Alan Norton, Alyn Rockwood
Issue Date:March 2003
pp. 22-31
<p>The article evaluates a method for enabling progressive client-server volume visualization of data from the computing grid. Rendering is performed on clients, while servers on the grid provide volume data in wavelet-compressed form. The client pri...
“Hot spot” contention and combining in multistage interconnection networks
Found in: IEEE Transactions on Computers
By Gregory F. Pfister,V. Alan Norton
Issue Date:October 1985
pp. 943-948
The combining of messages within a multistage switching network has been proposed [1], [11], [14] to reduce memory contention in highly parallel shared-memory multiprocessors, especially for shared lock and synchronization data. This paper reports on a qua...
Petascale WRF simulation of hurricane Sandy deployment of NCSA's cray XE6 blue waters
Found in: Proceedings of SC13: International Conference for High Performance Computing, Networking, Storage and Analysis (SC '13)
By Mark Straka, Melvyn Shapiro, Peter Johnsen, Alan Norton, Thomas Galarneau
Issue Date:November 2013
pp. 1-7
The National Center for Atmospheric Research (NCAR) Weather Research and Forecasting (WRF) model has been employed on the largest yet storm prediction model using real data of over 4 billion points to simulate the landfall of Hurricane Sandy. Using an unpr...
Wired for speed: efficient routes in VRML 2.0
Found in: Proceedings of the second symposium on Virtual reality modeling language (VRML '97)
By Alan Norton, Daniel J. Woods, Gavin Bell
Issue Date:February 1997
pp. 133-138
There are many reasons for integrating industry's software technology into the university system at the graduate level. This paper discusses efforts by TRW, Rational Software Corporation, and the University of Southern California's Software Engineering dep...
Interactive simulation in a multi-person virtual world
Found in: Proceedings of the SIGCHI conference on Human factors in computing systems (CHI '92)
By Alan Norton, Christopher Codella, Chu P. Wang, Daniel T. Ling, David A. Rabenhorst, Greg Turk, J. Bryan Lewis, James S. Lipscomb, Lawrence Koved, Paula Sweeney, Reza Jalili
Issue Date:May 1992
pp. 329-334
A multi-user Virtual World has been implemented combining a flexible-object simulator with a multisensory user interface, including hand motion and gestures, speech input and output, sound output, and 3-D stereoscopic graphics with head-motion parallax. Th...
Generation and display of geometric fractals in 3-D
Found in: Proceedings of the 9th annual conference on Computer graphics and interactive techniques (SIGGRAPH '82)
By Alan Norton
Issue Date:July 1982
pp. 61-67
We present some straightforward algorithms for the generation and display in 3-D of fractal shapes. These techniques are very general and particularly adapted to shapes which are much more costly to generate than to display, such as those fractal surfaces ...
Clamping: A method of antialiasing textured surfaces by bandwidth limiting in object space
Found in: Proceedings of the 9th annual conference on Computer graphics and interactive techniques (SIGGRAPH '82)
By Alan Norton, Alyn P. Rockwood, Philip T. Skolmoski
Issue Date:July 1982
pp. 1-8
An object space method is given for interpolating between sampled and locally averaged signals, resulting in an antialiasing filter which provides a continuous transition from a sampled signal to its selectively dampened local averages. This method is appl...
