VisIt
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.

- 15 Nov 2008 00:58
Changes: This release includes several new features and bugfixes in addition to performance enhancements for AMR data. The Volume plot now supports lighting when using ray casting, and the plot is also more efficient when rendering uchar data. Various improvements to annotations have been made. Specifically, plot legends can now be displayed horizontally. The Slice, Threshold, and Tube operators provide new options. The Silo, PDB/Flash, ITAPS, MFIX, PlainText, Tecplot, and SAMRAI readers have been enhanced or had bugs fixed. VisIt can now read data from the Gadget 2 SPH code.

Changes: This release includes many feature enhancements and bugfixes. The Streamline plot has been vastly improved to support creation of streamlines across domain boundaries, parallelism, and better numerics. VisIt's user interface can now be translated into other languages using Qt linguist. This release attempts to use the loopback network interface (127.0.0.1) to avoid socket issues. It can use the IceT rendering library on clusters. Many file format readers have been improved, including Tecplot (support for binary files), XDMF, PlainText, FLASH, and EnSight.

Changes: This release fixes important bugs found in the 1.9.0 major release, including several crashes. In addition, improvements have been made to the XDMF, CGNS, SimV1, Silo, Miranda, and Exodus database reader plugins. Recent changes in support deprecate the visit-help@llnl.gov email list for the better visit-users@email.ornl.gov email list, which provides archival. Finally, a VisIt wiki and user forum are available at www.visitusers.org.

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.
