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.

What is new in this release:

• Several enhancements have been made for Windows, including better SSH connectivity, metadata identifying VisIt programs, and PySide support.
• Multiple bugs related to AMR meshes have been fixed.
• The CGNS, ANSYS, and CRASH readers have been improved.

What is new in version 2.4.2:

• This is primarily a bugfix release which resolves issues in several areas.
• VisIt can now build without Mesa, enabling broader support for Ubuntu.
• VisIt's rendering performance has been improved, making version 2.4.2 at least as fast as versions prior to VisIt 2.4.0.
• Text annotations have been fixed so they are no longer truncated.
• A number of improvements have been made to the handling of variables restricted to specific materials.
• Material selection now works correctly with AMR data sets when changing time steps.
• Errors have been corrected in the GMV, Nek5000, and Wavefront OBJ plugins.

What is new in version 2.4.0:

• This release 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.

What is new in version 2.3.1:

• This release 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.

What is new in version 2.3.0:

• This version 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.

What is new in version 2.2.2:

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

What is new in version 1.12.0:

• This release offers a new, richly featured, parallelized Streamline plot that can integrate across domain boundaries.
• It offers a new Poincare plot for analysis of magnetic fusion datasets.
• The ParallelCoordinates plot was optimized, and can now display focus highlights.
• Many improvements have been made to VisIt's database reader plugins.
• In addition, dozens of bugs were fixed.

What is new in version 1.11.0:

• 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.

What is new in version 1.10.0:

• 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.
