Volume rendering of a 156,642 tetrahedral oil reservoir data set using 222 RBF functions organized in a hierarchy of 49 cells. Fragment programs are used to interactively reconstruct the compact functional encoding stored in texture maps. The bluntfin data set displayed has been encoded hierarchically with 695 RBFs, with 238 cells and a maximum of 60 RBFs per cell. We used a set of fragment programs with up to 60 basis functions for rendering the data set at interactive rates. Using 64 slices the data set renders at approximately 3.7 fps on a GeForceFX 5900 Ultra graphics adapter. The images shows a semi-transparent volume rendering and an isosurface rendering (isovalue 0.5) of the 80th time step of temperature generated from a natural convection simulation of a non-Newtonian fluid in a cube. The displayed fragment program based reconstruction of the functional encoded data field allows interacitve rendering up to several frames per second.
