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.

Recent releases


Release Notes: This version contains many enhancements and bugfixes. It was upgraded to VTK 5.8.0. Windows distributions now contain a parallel compute engine based on MSMPI. Cumulative query selections were enhanced so they can cache intermediate results obtained from executing filters over time. Queries provide a more uniform interface in the Python interface. 2D multi-resolution rendering capability was added for 2D AMR data. The Streamline plot now works with AMR data. Libsim now allows mesh-sized ghost zone arrays to be used.


Release Notes: This version is primarily a bugfix release and resolves outstanding issues in several areas. Errors in the Volume plot and Streamline plot were fixed, as were errors in the Threshold and IndexSelect operators. Other fixes were made to Libsim and various reader plug-ins.


Release Notes: This release includes several enhancements and bugfixes. Selections have been enhanced to support cumulative queries, which are time-aware selections that use multiple variables and histograms to reduce data. Pick over time now supports multiple variables. VisIt can now start a remote compute engine through a gateway machine. Libsim was enhanced to have SWIG-generated Python bindings, support for dynamic user interfaces, and improved startup functions. Several database reader plug-ins were improved, including the Cale, GMV, Velodyne, Nek5000, and Xdmf readers.


Release Notes: This version is primarily a bugfix release and resolves outstanding issues in several VisIt database readers, including ParaDIS, Miranda, and EnSight.


Release Notes: This release includes several enhancements and bugfixes. VisIt's simulation instrumentation library was ported to the Windows platform. Lineout can now be used directly on plots to extract data from a higher dimensional plot. The Streamline plot was enhanced to support caching of intermediate results, accelerating its performance. The Streamline plot was made easier to use and extended to generate pathlines. A new operator was added to remove the cracks that form at AMR patch boundaries during isocontouring.
