************ NOW: Featuring AMR PARAVIEW Visualizations! ************
[ see VTF gallery ]




featured work: VTF
pasadena, ca, 2000-2007

this gallery is a small sample collection of images resulting from different parts of the ASC project at caltech. for a more uniform view of current work, please referr to the vtf-wiki online documentation manual and tutorials (coming soon).

current focus of the visualization effort includes:
  • enabling scalable visulization of AMR data sets on researchers workstations (data dumped by amroc, visualizaed using paraview)
  • research into algorithms for large data visualization (such as point based realtime exploration of large unstructured meshes)
  • investigation of visual frameworks (visual programming environments) to enable large simulation setup, steering, debugging, and visualizing of results
  • exploring the creation of a small size visualization cluster for use by researchers to interactively visualize indiscriminately large datasets
  • the rayleigh-taylor instability
    Shown in these figures are composites of several different renderings of the denisity field arising from the simulation of the Rayleigh-Taylor instability - a fundamental instability which occurs whenever light fluid is accelerated into heavy fluid and which gives rise to turbulence and mixing. An isosurface of density has been superposed on the three dimensional grid used in the simulation. At each point in the grid the local density is indicated via a small sphere color coded by the density. The simulation (with a resolution of 512 points in each direction) was performed on the LLNL ASCI Blue machine by Dr. A. Cook of LLNL. The data sets were then analyzed at Caltech.
