Abstract

A forecasting system for the Great Lakes in which the data generated by a three-dimensional numerical model is visualized by a 3-D/stereoscopic display module is discussed. The module consists of a control panel and a display window with the capability of interactively rendering the results. The event scheduling for scenario testing to steer the 3-D numerical model is achieved by a similar panel. These panels set up the simulation and control the data flow between the graphics workstation and supercomputer. Rendering methods, stereo imagery, and animation are incorporated to display the results. Interaction between the user, the workstation, and the supercomputer allows steering of the simulation and tracing of the simulation output. Distributed software for postprocessing and volume rendering are used to enhance the representation
