CashFlow, A Visualization Framework for 3D Flow - Studierstube ...

Software Design3.11. Loader Nodes• Surface RendererThis renderer is similar to the wire–frame renderer. The grid is rendered usingsurfaces.• Streamline RendererRendering of streamlines in different ways. In extension to the default streamlinerenderer an up–vector per each interpolation point can be taken into account tovisualize vorticity.• Polygonal RendererSimply renders polygonal data.• Volume RendererCashFlow does not use its own volume renderer, because a volume renderercalled SimVoleon[Vol10] is already available in Coin3D[Coi00].3.11 Loader NodesUnfortunately there are several binary data formats for CFD data sets and medical datasets. Due to the large dissemination of some packages a set of data formats becamemore important. This is far away from a standardization of data formats, but it alsoreduces the number of loaders needed.Since it is not useful to implement several loaders to proof that a visualizationalgorithm works correct we decided to use only two loaders at the moment:• CFD Plot3Dfor computational fluid dynamics (CFD) data sets• CT data setfor medical data sets.63
