Visualization methods and simulation steering for a 3D turbulence model of Lake Erie

Abstract

A computational model of Lake Erie serves as a framework for a study of visualization techniques and display methods. Various display methods are used to examine the 3D data. The methods use primitive representations of polygons, volumes, lines and particles. The display methods also incorporate stereo imagery and animation. Three techniques of integrating the control of the computational model and the display of images are discussed. These visualization techniques are post-processing, tracking and steering. A distributed software environment is used which implements these visualization techniques and display methods. The technique of steering is emphasized with a description of the software requirements and examples. A signficant increase in productivity and comprehension is shown when steering is used.
