15 VisBench: A Visualization Workbench A multi-platform collection of tools for visualization capabilities Provides access (possibly from under- powered resources) to Vis functionality running on high-powered resources. Important for remote users and/or for big data. Provides visualization functionality for the Grid

16 National Computational Science Alliance VisBench Components VTK Server RenderMan Server Object Request Broker (CORBA) Java Client CAVE Client Terrain Server Geometry Client Problem-specific Workbench MATLAB Server File Server O2K

17 National Computational Science Alliance (Visualization Toolkit) VTK Server open source, 3D computer graphics, image processing, and visualization. hundreds of algorithms object oriented (C++) other language bindings for RPD (Tcl/Tk, Python, Java) Unix/Linux, Windows threads, MPI support active user community www.kitware.com/vtk.html

18 National Computational Science Alliance MATLAB Commercial pkg; well-respected; >20 yrs old LINPACK/EISPACK=>LAPACK concise scripting language interface large archives of existing scripts www.mathworks.com/products/matlab VisBench: offer higher-level analysis tools & interfaces that use MATLAB

19 National Computational Science Alliance VisBench Java Client Build vis pipeline Control vis parameters Handle multi-files (time-series) Apply analysis techniques Export images, VRML Save session as XML

20 National Computational Science Alliance CFD Feature Extraction

21 National Computational Science Alliance Future: The Grid  Provides access to resources anytime, anyplace  Connects dispersed research teams, fostering communication and collaboration  Couples machines used for simulation + machines used for visual analysis/mining + databases
