VisIt 2.12.3

An interactive parallel visualization and graphical analysis tool for viewing scientific data

VisIt is a point-and-click 3D scientific visualization application that supports most common visualization techniques (e.g., iso-contouring 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.

VisIt supports visualization and analysis of a wide range of computational meshes, including two- and three-dimensional rectilinear, curvilinear, and unstructured meshes as well as structured AMR and CSG meshes.

VisIt provides extensive functionality for interactive and static visualization and analysis of extremely large data and also has the ability to animate data, allowing users to see the time evolution of their data and create movies.
