Abstract

In the past a lot of work has been invested in various aspects of an interactive visualization of CFD simulation data. This includes e.g. increasing the rendering speed and responsiveness of complex visualizations, using and enhancing multimodal user interfaces, and incorporating parallel approaches for an ef cient extraction of ow properties and their respective visual representation. Still, only few projects combine the signi cant advances in these areas. In this paper, we describe our software framework ViSTA FlowLib, which facilitates merging current research results of various related areas. This is done by connecting dedicated sub-modules with clearly defined responsibilities through appropriate interfaces, whilst implementing sensible default behavior. ViSTA FlowLib combines efficient rendering techniques and a parallel computation of the visualization with intuitive multimodal user interfaces to allow for an interactive exploration of unsteady fluid flows in a virtual environment. Special care has been taken to achieve a high scalability in respect to computing power, projection technology, and input-output device availability.
