ParaView 3.10.0 Now Available

The ParaView team is pleased to announce the availability of the ParaView 3.10.0 final binaries for download on the ParaView download page. The ParaView 3.10.0 release features several notable new features and improvements, described below.  For an exhaustive list of the new features and bug-fixes, please refer to the change log at: http://www.paraview.org/Bug/changelog_page.php.

For the 3.10 release,  we have added 60 new readers, which include: ANSYS, CGNS, Chombo, Dyna3D, Enzo, Mili, Miranda, Nastran, Pixie, Samrai, Silo, and Tecplot Binary. A full listing of supported readers can be found in the ParaView Users Guide. We also added the ability for developers to create ParaView reader plugins from previously developed VisIt reader plugins. You can find a full guide on how to do this on the VisIt Database Bridge.

With this release we have rewritten the ParaView User's Guide and are making it freely available for the first time. The complete guide can be obtained in the help system or online through the ParaView User's Guide wiki. This guide is continually being updated, and will form the basis for a new print edition of the guide..

We have included a Python-based calculator which makes it possible to write operations using Python. The Python calculator uses NumPy, which lets you use advanced functions such as gradients, curls, and divergence easily in expressions. Also the NumPy module is packaged in the ParaView binary and is importable from the ParaView Python shell.

To better utilize multiple cores on modern multi-core machines, by default ParaView can now run using a parallel server, even for the built-in mode. This enables the use of all the cores for parallel data processing, without requiring the user to start a parallel server. ParaView binaries will also be distributed using an MPI implementation, making this feature available to users by simply downloading the binaries. Since this is an experimental feature, it is off by default, but users can turn it on by checking the Auto-MPI checkbox in the application settings dialog.

Additionally, the 3.10 release includes several usability enhancements. 3D View now supports smart context menus, accessed by right-clicking on any object in the 3D View to change its color, representation, color map and visibility. Left-clicking on an object in the 3D View makes it active in the pipeline browser. Within the spreadsheet view, sorting is now supported and an advanced parallel sorting algorithm ensures that none of the benefits of the spreadsheet view, such as streaming and selection, are sacrificed. Python tracing and macro controls are no longer hidden on the Python shell dialog and instead are now easily found on the Tools menu.

We have improved the rendering pipeline to better handle composite datasets, which leads to a marked performance improvement for users dealing with large multi-block datasets. For developers interested in adding support for advanced multi-pass rendering algorithms to ParaView, this release includes a major refactoring of ParaView's rendering pipeline. View and representations have been redesigned and users should see improved performance in client-server mode from reduced interprocess communication during rendering.

LANL's MantaView interactive ray tracing plugin has been restructured to make it easier to use. Version 2.0 of the plugin is now multi-view capable and no longer requires ParaView to be run in a client/server configuration. Similarly both of LANL's streaming aware ParaView derived applications have been merged into ParaView proper in the form of a new View plugin. The underlying streaming algorithms have been rewritten to be more usable and extensible. Both plugins are available in standard binary package for the first time in this release.

As always, we rely on your feedback to make ParaView better. Please use http://paraview.uservoice.com/ or click on the "Tell us what you think" link on paraview.org to leave your feedback and vote for new features.
