Presentation Transcript

  1. Immersive Visualization of the Hurricane Isabel Dataset Kenny Gruchalla and Jonathan Marbach BP Center for Visualization University of Colorado at Boulder

  2. A First Look

  3. BP Center for Visualization • Research in Visualization and Immersive Virtual Reality • www.bpvizcenter.com

  4. The Immersive Drilling Planner (IDP) • A tool for planning oil and gas wells

  5. What does that have to do with the Contest? • We adapted the Immersive Drilling Planner (IDP) to load the Hurricane Isabel Dataset: • Added capabilities for time-varying volume and vector data • Added timestep controls • Added transfer function editing • Added data probes • …and we called it AtmosV!

  6. The Video • Available atwww.jonmarbach.com/isabel

  7. AtmosV and the Contest • Contest Goals • Interactivity • Exploration • Fusion • Our Solution • Immersive, Real-time visualization (Performance does matter!) • Timestep control, Real-time Text Probes and Temperature Probes, Dataset choice, Transfer function editing, Vector-plane selection • Simultaneous visualization of multiple characteristics

  8. Challenges • Performance/Memory Tradeoff (SGI Onyx 3800 vs Cluster) • Vector Volume size (Tried using RGBA encoded vectors and Vertex Texture Fetch – card/drivers aren’t quite ready) • Vector Volume size (Tradeoff between full data integration and full timestep display) • Downsampling (Tradeoff between quality and memory footprint) • What does it mean to be Immersed in a Volume?
