Exploring Instationary Fluid Flows by Interactive Volume Movies
Volume rendering offers the unique ability to represent inner object data and to realize enclosed structures “at first glance”. Unlike software-based methods, the use of more and more available special-purpose hardware allows volume rendering at interactive frame rates-a crucial criterion for acceptance in industrial applications, e.g. CFD analysis. Careful optimizations and the exclusive use of hardware-accelerated data manipulation facilities even enable volume rendered movies supporting real time interactivity. This article presents the most important features and implementation issues of an OpenInventor-based stereoscopic, VR-featured volume rendering system for instationary datasets.
