VisIt is an interactive parallel visualization and graphical analysis tool for viewing scientific data. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. It was designed to interactively handle very large data set sizes in the terascale range, and works well down to small data sets in the kilobyte range. License: BSD License (revised) Changes: This release includes a number of bugfixes and new features. It supports setting the background for a visualization to a user-specified image, which can be tiled flat or used as a spherical background that moves with the camera. It has a new annotation that inserts extruded text into a 3D visualization. The query infrastructure has been improved, and new queries were added. The plot list now provides a context menu that offers per-plot controls.
