  1. HPCC Review Part I: VRML (FY 1999 - NGI/NW/02) Christopher W. Moore, Nancy N. Soreide, NOAA/PMEL Cathy Lascara, Glenn Wheless, Old Dominion University HPCC Project Review Meeting, Norman, Oklahoma, 24-25 May 2000

  2. VRML: Construction of Complex 3-D Worlds • Accomplishments: • Several Virtual worlds created from NOAA projects: • TAO, FOCI, Vents • Several Java-based VRML creation tools have been developed • “Cron” jobs use these tools to update worlds using latest data • Presentations/publications at professional meetings • Including three invited talks

  3. Using VRML Building a single, complex VRML world in gave us coding experience. Creating Java/VTK tools for the creation of VRML objects allowed us to quickly make virtual reality demonstrations for several of the NOAA projects

  4. VRML: A First Lesson Bathymetry in Astoria Canyon offshore from the Columbia River outflow in Washington State, in 2D and 3D. 2D plot High frequency spikes in the bathymetry data are obvious in the 3D plot (right) and are obscured in the 2D plot (above). Calculations of bathymetry gradients to identify regions of internal tide generation would be impacted by these spikes in the bathymetry data. 3D plot Data courtesy of Robert Kamphaus, NOAA Vents Program

  5. Building VRML Worlds - Java Tools Several Java tools using were designed to build the VRML worlds using VTK’s Java bindings: VTK is an open source, freely available software system for 3D computer graphics, image processing, and visualization. Worlds we created using these tools include ...

  6. VRML: TAO/Global Carbon Cycle Program Data from the TAO buoy array and ship-board CO2 measurements are visualized with a VRML-animator developed at PMEL Animate *Drs Mike McPhaden, Dick Feely, NOAA/PMEL

  7. VRML:FOCI A Fisheries-Oceanography virtual world was made from data from Al Hermann’s SCRUM model output Click for VRML demo Dr. Al Hermann, NOAA/PMEL/FOCI

  8. Global data sets • Several global gridded data sets* • were made into VRML visualizations: • ETOPO30 • SST • Climate data • VRML demo *Courtesy Steve Hankin, NOAA/PMEL/TMAP

  9. VRML Stereographic Virtual Reality Stereo 3D, interactive virtual reality visualizations are not difficult for a scientist to create or to view, from the web or from the desktop, and the effect can be enhanced dramatically by including the capability of stereographic viewing. With a PC and a 99-cent pair of red/green sci-fi glasses, the spheres and vectors will pop out of the page in stereo, revealing the true 3D location of the fish, the steep slopes of the bathymetry, and the vertical motions near the submarine canyon. The images can be rotated, animated and zoomed. Fish larvae and velocity vectors in a submarine canyon, from a circulation model of Pribolof Canyon in the Bering Sea. Use red/green glasses to see images on the right in stereo. Stereo Courtesy of Al Hermann, NOAA/PMEL FOCI Project

  10. VRML Publications & Presentations • Invited to: • NOAATech2000 • Outstanding Technology Achievement Award • SuperComputing ‘99 • Canadian Statistical Society Meeting • Other presentations: • AMS 1999 - Dallas • GOIN 1999 - Honolulu • AMS 2000 - Long Beach http://www.pmel.noaa.gov/vrml
