VisIt - 3D Scientific Visualization

VisIt is a point-and-click 3D scientific visualization application that supports most common visualization techniques (e.g., isocontouring and volume rendering) on structured and unstructured grids. Due to its distributed and parallel architecture, VisIt is able to handle very large datasets interactively. In addition, VisIt is extensible, allowing users to add data loaders or additional analysis tools to VisIt. The NERSC Analytics Group has developed extensions to VisIt to support NERSC user applications, and coordinates with the VisIt development team to add these extensions to the main VisIt development code branch.
