SAN ANTONIO, TX -- SGI (NYSE: SGI) is featuring immersive, interactive displays of its industry-leading collaborative visualization technologies at the Society of Exploration Geophysicists 2001 International Exposition and Annual Meeting, which is taking place in San Antonio through this Friday, Sept. 14. SGI is a leader in technologies that allow oil and gas companies around the world to analyze geoscience and engineering data in highly visual, three-dimensional formats for exploration and development of hydrocarbon reservoirs. This includes walks through the subsurfaces to see the geometric relationship between faults and the reservoir strata. Re-creating the types of wall display and visualization rooms that SGI has provided to oil and gas companies worldwide, the SGI booth includes a three-channel SGI(TM) Reality Center(TM) 3300W wall display that is driven by an SGI(TM) Onyx(R) 3400 visualization system. It sits within an 18-seat theater that features demonstrations on the hour of a wide variety of independent software vendor applications. At oil and gas companies around the world, data are increasingly viewed simultaneously and collaboratively by multidisciplinary teams dispersed in locations around the world. The Reality Center 3300W display illustrates how the combination of high-performance computing and data management technologies with advanced collaborative visualization capabilities allows geoscientists, engineers and researchers to gain new insight through analysis of critical data in innovative and cost-saving ways. The OpenGL Vizserver(TM) computing solution, which delivers advanced visualization system capabilities and performance to the desktop, is being demonstrated in both UNIX(R) and Windows NT(R) environments. Further details about OpenGL Vizserver are available at www.sgi.com/software/vizserver/overview.html . The SGI booth will also preview an innovative display technology for the Silicon Graphics(R) Octane2(TM) visual workstation that offers optimum visualization for geophysical applications over multiple monitors. The technology is built on a combination of the VPro(TM) V12 graphics subsystem, the most advanced desktop graphics available today, and a unique implementation of SGI display capabilities. The new display technology demonstrates applications being used at the new BP Center for Visualization at the University of Colorado, which was established last year by a donation of hardware, software, intellectual property and seed funding from BP, with subsequent contributions from SGI.
