| 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. |

| Volume rendering of the Super Pheonix (spx) data set using hardware-based ray casting. A technique similar to depth peeling is employed in order to handle this non-convex data set. | Volume visualizations of tetrahedral meshes which have been encoded in a compact texture representation based on tetrahedral strips and are stored in the texture memory of the graphics adapter. The renderings have been computed with a ray casting algorithm for programmable graphics hardware adapted for this mesh representation. |
