My CAVEvis tool for the visualization of scientific datasets. The tool supports astronomical datasets (FITS) as well as HDF. It allows the user to view isosurfaces as well as slices.

The tool uses vtk for the visualization algorithms and renders using Performer. This is made possible by my vtkActorToPF. In fact, vtkActorToPF is used to parallelize vtk (by data decomposition). This is done by having multiple vtk pipelines feeding a shared Performer scenegraph. Each pipeline is in its own process and works on a piece of the dataset. For example, in the snaphot above, each quadrant is being computed on a seperate processor.

An earlier version of this tool was demonstrated by Paul Sotirelis at Supercomputing '97.
