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




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
Visualization with SCV – Dec 2008
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

Visualization with SCV – Dec 2008
Example workflow –
