A bulk movie playback package (bplay) integrated into the OptIPuter’s Scalable Adaptive Graphics Environment (SAGE) coordinates and displays multiple incoming streams of high-definition digital images over optical networks. NCSA participates in the Global Lambda Visualization Facility (GLVF). This research is funded by the USA National Science Foundation OptIPuter and LOOKING projects, the Office of Naval Research and the State of Illinois. Future plans include connecting NCSA to ACCESS DC and TRECC DuPage with optical networks for collaboration among sites.

The following high-definition, uncompressed, stereo visualizations are being streamed from NCSA to iGrid:
  • Development of an F3 Tornado within a Simulated Supercell Thunderstorm (Simulation by: Wilhelmson, Gilmore, et. al., UIUC, USA; Wicker, NSSL / NOAA, USA)
  • Jet Instabilities in a Stratified Fluid Flow (Simulation by: Kraig Winters, Scripps Institute of Oceanography, UCSD, USA)
  • Flight to the Galactic Center Black Hole (a visual excerpt from “Blackhole: The Other Side of Infinity,” a planetarium dome production by the Denver Museum of Nature and Science, NCSA, and Thomas Lucas Productions, USA)
  • Interacting Galaxies in the Early Universe (Simulation by: Michael Norman, Brian O’Shea, UCSD, USA)
