Overview
• (Ancient) History• GeoWall• GeoWall2
• PG2• Software• Science• Future
Geoinformatics 2006 5/8/2006 3
History (Ancient)1990 High-Performance Computing & Communications
2000 USGS Prospectus-funded Beowulf Cluster Research Project
was the Catalyst
2001 Initial GeoWall Meeting
2002 GeoWall Consortium formulation; serial #3 at UGSS/EROS
2003 Invited to participate in NSF OptIPuter grant
2004 Commercial software catching up with GeoWall technology
2005 More focus on OptIPuter, less on GeoWall Consortium
2006 Deployment to Geoscientists

History (Recent)
• We are descendents of CAVEs (Virtual Reality) - Very expensive
• Dual-output (Stereo) graphics cards for PC Motherboards - Inexpensive
• CAVElib port to linux• GeoWall Consortium Formulation• Hardware < $10K• Windows and OS X apps• Commercial GIS Software

Status
• Affordable 3D stereo visualization• Research collaborations initiated• Over 500 by Dec. 2005, current est. = ?• 10% of all U.S. Geology undergraduates• Over 15 museums• 20 papers and presentations at 2003 AGU• One half-day Session at 2004 AGU• Integrating into Geology curriculums in 2005
(MN, NAU)• 2006: Deployment outside academia
Geoinformatics 2006 5/8/2006 14
GeoWall2
• GeoWall2 (PerspecTile)• Cluster-based tiled display -- large screen
real estate
• OptIPuter• 64-bit visualization software• Designed for high-bandwidth
interactive visualization

Background• USGS Prospectus-funded Research Project
had tiny visualization component• Momentum from development of GeoWall
Consortium• Geo – Geology (Geography… Geometry… Geo…)• Wall – One wall of a cave – descendent of CAVElib• 3-D Viz on the cheap
• GeoWall Consortium - formulation without funding
• Jason Leigh University of Illinois – Chicago (UIC), Electronic Visualization Laboratory (EVL) – Cave Technology
• Peter van Keken, University of Michigan - Geology• Paul Morin, U of Minnesota – Geology Visualization,
Wall Evangelist• Brian Davis, EROS – Data Pimp
