IndeGS: Index Supported Graphics Data Server for CFD Data Postprocessing

Virtual reality techniques particularly in the field of CFD (computational fluid dynamics) are of growing importance due to their ability to offer comfortable means to interactively explore 3D data sets. The growing accuracy of the simulations brings modern main memory based visualization frameworks to their limits, inducing a limitation on CFD data sizes and an increase in query response times, which are obliged to be very low for efficient interactive exploration. We therefore developed “IndeGS”, the index supported graphics data server, to offer efficient dynamic view dependent query processing on secondary storage indexes organized by “IndeGS” offering a high degree of interactivity and mobility in VR environments in the context of CFD postprocessing on arbitrarily sized data sets. Our demonstration setup presents “IndeGS” as an independent network component which can be addressed by arbitrary VR visualization hardware ranging from complex setups (e.g. CAVE, HoloB...
