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.
This release includes a number of bugfixes and new features. VisIt can be built automatically with the build_visit script on many Linux, Mac OS X, and AIX platforms. The build_visit script downloads relevant VisIt and 3rd party source code, and configures and builds it all using your C++ compiler. This release can tunnel its network connections through SSH, has support for reading several new file formats, and has a new Macros window that allows 1-click access to user-defined Python functions. Support for user settings and file association on the Windows platform has been improved.
