  3. The Visualization Pipeline - Software SCV Visualization Workshop – Fall 2008 Data acquisition and preparation Sci vis tools Geometric representation Rendering Post-processing

  4. Data analysis tools SCV Visualization Workshop – Fall 2008 • Matlab and IDL • Powerful mathematics libraries • Basic sci vis tools • Simple rendering

  5. Scientific visualization tools SCV Visualization Workshop – Fall 2008 • VTK, Paraview • Limited mathematics processing • Specialized sci vis tools • Built for speed / interactivity • Decent rendering

  6. Graphics / Display SCV Visualization Workshop – Fall 2008 • OpenGL, OpenSceneGraph, SGI Performer • Packages for programming graphics • Flexibility and control

  7. Rendering, modeling, animation SCV Visualization Workshop – Fall 2008 • Maya • Sophisticated user interface • Powerful modeling tools • Beautiful rendering

  8. 2D graphics and movies SCV Visualization Workshop – Fall 2008 Adobe Photoshop (and Gimp) Adobe Premiere

  9. Plotting SCV Visualization Workshop – Fall 2008 Matlab, IDL Gnuplot, Xmgrace Excel

  10. Virtual Environments SCV Visualization Workshop – Fall 2008 DAFFIE

  11. General data wrangling SCV Visualization Workshop – Fall 2008 C / C++, Fortran, Perl, Java, etc

  12. Example workflow – molecular dynamics • Simulation creates data files • Molecule x,y,z + type •  colored spheres (C program) • Electron density as volume data •  isosurfaces (IDL)  .obj files • Rendered in Maya SCV Visualization Workshop – Fall 2008

  13. Example workflow –pressure on turbine • Simulation run on supercomputer • Produced many Plot3d files • C code transforms data to .obj files • Rendered in Maya • Processed using Imagemagick for DVD Wall movies SCV Visualization Workshop – Fall 2008

  14. Example workflow –showing entropy • Isosurfaces in IDL • Convert output into .obj • Render in Maya, with transparency • View in 3D on Wall SCV Visualization Workshop – Fall 2008

  15. Example workflow –stretched water • Given positions of atoms in water • How to show “holes”? • Construct volume data of distance • Use volume visualization SCV Visualization Workshop – Fall 2008

  16. Example workflow –CISM • Researchers used OpenDX • SCV staff modified OpenDX networks • Produced wall movies and demos SCV Visualization Workshop – Fall 2008

  17. Many posiible workflows SCV Visualization Workshop – Fall 2008 Data Matlab VTK OpenGL Maya IDL Paraview OSG Photoshop Gnuplot DAFFIE Performer Premier Xmgrace Excel
