Integration of Access Grid and ParaView to enable remote participants to interact with their visualizations in a coordinated manner across all sites, to improve information flow and expedite visualization development and scientific results. This will remove a significant bottleneck in achieving visualization results and understanding, by allowing participants to exchange data interactively while exploring their data visually. In this first development, specific areas of ParaView functionality will be targeted for inclusion in the shared interaction, based on feedback from the domain scientists as to the areas of highest relevance and impact.
