2 The Visualizion Pipeline - Hardware SCV Visualization Workshop – Fall 2008 Field instruments Scientists/programmers  Supercomputers  Graphics machines  Publications, movies/DVDs, web Demos, educational software

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

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

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

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

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

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

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

10 Virtual Environments DAFFIE SCV Visualization Workshop – Fall 2008

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

12 Example workflow – molecular dynamics SCV Visualization Workshop – Fall 2008 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

13 Example workflow – pressure on turbine SCV Visualization Workshop – Fall 2008 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

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

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

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