Construction of Complex 3-D Worlds Invited to: NOAATech2000 outstanding achievment award SuperComputing ‘99 Canadian Statistical Society Meeting Other presentations: AMS Dallas GOIN Honolulu AMS Long Beach

Using VRML - Leveraging from 1998 Building a single, complex VRML world in FY98 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

A First Lesson 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. Bathymetry in Astoria Canyon offshore from the Columbia River outflow in Washington State, in 2D and 3D. Data courtesy of Robert Kamphaus, NOAA Vents Program

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

VRML: TAO/GCCP Data from the TAO buoy array and ship-board CO 2 measurements are visualized with a VRML-animator developed at PMEL Animate

VRML:FOCI A Fisheries-Oceanography virtual world was made from data from Al Hermann’s SCRUM model output Click for VRML demo

Global data sets Several globel gridded data sets were made into VRML visualizations: ETOPO30 SST Climate data VRML demo

Stereographic Virtual Reality Courtesy of Al Hermann, NOAA/PMEL FOCI Project, under HPCC supported VRML project. 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.

Conclusions: Milestones passed Several Java-based VRML creation tools have been developed “Cron” jobs use these tools to update worlds using latest data Several professional meetings were attended, including three invited talks Virtual worlds created from NOAA projects: TAO FOCI VENTS
