[Paraview-developers] ANN: ParaView 4.1.0 is available for download

[Utkarsh Ayachit]

Folks,


ParaView 4.1.0 is now available for download (
http://paraview.org/paraview/resources/software.php). With over 170 issues
resolved, this release includes several bug fixes and feature enhancements.
For a detailed list of issues resolved, refer to the change log (
http://paraview.org/Bug/changelog_page.php).  Some of the notable
enhancements in this release are as follows:

*Redesigned Color Map Editor panel*

This release introduces a completely designed panel for editing color and
opacity transfer functions for scalar coloring. The panel, which is now a
dockable widget, instead of a popup dialog, makes it easier to edit
transfer functions as well as edit labels and annotations on the color
legend or scalar bar. This also makes it easier to access some of the
functionality introduced in the previous version of ParaView, such as
categorical colors. It is now easier to edit transfer functions when using
log scaling as the transfer function editor view now switches to log space.



*Enhancements to Find Data dialog*

Find Data dialog, introduced several versions ago, has quickly become of
the main mechanisms for creating new selections. However, until now, if the
user created selection using some other mechanism, such as selecting cells
in the 3D view, the Find Data dialog could not be used to inspect that
selection. One had to use what was called the Selection Inspector. That has
now been changed. Find Data dialog has been updated to always show the
active selection, no matter how it was created.

Selection Inspector panel has been removed. Selection Inspector was
primarily used to control how selections are labelled, their font
properties, etc. One can affect these directly from the Find Data dialog or
the new Selection Display Inspector which is dockable panel specially
designed for picking selection labels, label properties, or showing the
selection frustum for frustum based selections.



*Enhancements for interactions with Plots*

Inspired by plots in matplotlib, individual axes in line and bar charts can
 now be zoomed by right-clicking and dragging along the x- or y- axis. Of
course, one can still drag diagonally to scale both axes as before. Also
the the user interactions for making new selections in line chart view have
been cleaned up to be more consistent with the render view.

*Support for Python-based views*

This release adds mechanisms to enable Python developers to integrate views
that use libraries such as matplotlib for rendering. This will make it
possible to take ParaView’s charting capabilities even further. More
details on how to create such views can be found on Kitware blog (
http://www.kitware.com/blog/home/post/588).

*ParaView Catalyst: Zero-Copy infrastructure for transferring data*

A set of experimental interfaces have been added for reusing simulation
memory in portions of a Catalyst pipeline. A vtkMappedDataArray subclass
may be used for attribute/coordinate arrays, and vtkMappedUnstructuredGrid
is used for dataset topologies. More information can be found at
http://www.paraview.org/Wiki/CoProcessing#Experimental:_Reusing_simulation_memory
.

*ParaView Catalyst: Editions*

Several new editions of ParaView Catalyst are now available for download
and are routinely built and tested. These editions are:

Base

minimal set of dependencies needed for Catalyst

Base-Python

Base with Python support

Essentials

Base + dependencies needed for Calculator, Contour, Clip, Cut and Glyph
filters.

Essentials-Python

Essentials with Python support

Extras

Essentials + dependencies needed for ExtractHistogram, WarpScalar,
WarpVector, IntegrateAttributes, Extract Surface filters.

Extras-Python

Extras with Python support

*SurfaceLIC and support for Parallel Rendering*

One of the notable community contributions for this release includes
extensions to the ParaView Line Integral Convolution contributed by
Lawrence Berkeley National Laboratory (LBNL). Details can be found on the
Wiki (http://paraview.org/Wiki/ParaView/Line_Integral_Convolution). The
implementation has been designed to work with composite data in parallel
and includes a number of customizations that facilitate interactive data
exploration.

*Updates to ParaViewWeb*

ParaViewWeb was integrated into ParaView binaries in the previous release.
This release includes several fixes and enhancements to simplify use and
deployment as well as updates to the WebGL rendering support. This
implementation supports modern browsers with WebSocket capabilities
including Safari 6+, Chrome 14+, Firefox 11+ and IE 10+.

As always, we look forward to your feedback (http://paraview.uservoice.com).
