The Visualization Pipeline IS&T Scientific Visualization Tutorial – Spring 2010 Math Proc Scientific visualization Computer Graphics

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

The Visualization Pipeline - Software Visualization with SCV – Dec 2008 Data acquisition and preparation  Sci-vis tools  Geometric Representation  Rendering  Post-processing

Many possible workflows Visualization with SCV – Dec 2008 DataMatlabVTKOpenGLMaya IDLParaviewOSGPhotoshop GnuplotDAFFIEPerformerPremier Xmgrace Excel

Example using IDL Visualization with SCV – Dec 2008

Your Project Describe your work in visual / geometric way? What is goal, e.g., web, publication, presentation? What is the time line? How much learning time can you invest? How much do you expect to use? Visualization with SCV – Dec 2008

Example workflow – molecular dynamics Visualization with SCV – Dec 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

Example workflow – pressure on turbine Visualization with SCV – Dec 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

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

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

Example workflow – CISM Visualization with SCV – Dec 2008 Researchers used OpenDX SCV staff modified OpenDX networks Produced wall movies and demos

Example workflow – Corporate Connections Visualization with SCV – Dec 2008 Researchers provided data SCV staff wrote custom viewing code
