Improve parallelization for multi-processor machines
Since virtually all computers have at least 2, rather 4 or even more cores, it would be great to be able to utilize them.
For now, I haven't found a way to to postprocess OpenFOAM data or StarCD data in parallel on one machine and gain a speed-up. (infact, setup via "mpirun -np2 pvserver" decreased performance to 0.5x). I have read that the "not-legacy" VTK reader is parallel, so could there be at least a converter from old-VTK to new VTK? (if the reader is the problem)

actually implement the ideas listed here
only one of the top twenty ideas are things you're actually working on, and most of them were suggested years ago. maybe you should start looking into, say, the top five. just a thought.
the only items here that you've worked on are easy things you were going to implement anyway. clearly you only develop ideas you are specifically paid to develop. so why does this forum even exist?

Big-endian Ensight files
It worked up to 3.4, but no longer in 3.6. Would it be very difficult to re-introduce it?
1 voteParaVIew still supports big-endian EnSight files. The detection of endianness is now automatic so there is no longer need for a combo box for endianness.

Make it simpler to change the scale in the 3D view
It takes more effort that is necessary to rescale the colour bar, i.e.
* click the colour scale editor
* untick automatically rescale
* click rescale range
* update range in new dialog window
* click rescale
* close dialogThree suggestions:
* Remove the unnecessary extra dialog for the range (include in the main dialog window)
* Colour editor dialog could be available as a context menu from the 3D view
* Middle click and drag could select the range from the 3D view32 votesThe Color Map Editor available since ParaView 4.1 addresses several of these issues.

Make views dockable, including the Python shell
It would be nice if the python command shell and other views were made dockable, with an autohide feature like Visual studio. This would be productivity boost., and would be a quick way of increasing the size of the view window.
24 votesAs of 5.5, both Python shell and Output Window will be dockable.

Writing to Paraview from an external program
Paraview operates/implements a client-server paradigm. This suggests that it may be possible for an external (e.g. C++ application) to communicate with a running instance of Paraview, by sending it commands (e.g. open legacy VTK file) via the port attached to the server. Such a feature would be ideal for:
- debugging programs that output VTK data.
- automatically loading or unloading data to Paraview e.g. at the end of a smilation

3d widget plugins
title say it all, but I think the current design with xml "hints" needs some thought as well...
1 voteAlready supported. Look at ADD_3DWIDGET in ParaViewPlugins.cmake

Format Cube Axes
Till now, it's not possible to format the Cube Axes deciding Font/Size of the text, thickness of the ticks, etc ...
Font/Size of each axis' title is a very important feature: the size is usually quite big and the letters are super-imposed to the axis' lines.Adding this feature to Paraview would enhance it a lot
Thanks
152 votesA cube axes replacement, named ’Axes Grid
is now available in ParaView git/master and will be included in the next release of ParaView. -
Add a slider for "Slice" in the "View"
it would be very useful to add a slider (near or under) the rendered data in "view" for navigating between the slices like the one in the "object inspector".
cheers8 votesParaView 4.0 makes it easier to access “Slice” parameters in the Properties panel when data is shown as “Slice”.

Parallel Coordinates view with threshold selections & brushing
It would be extremely useful to have a parallel coordinates view of data arrays, but especially if there were selection tools on the axes which would act as threshold filters on the data. Brushing linked to coloring in the views would also be nice for quick associations between data values and locations in the view. All of this would naturally extend to scatter (and other) plots, as well. I think the addition of this type of interactive probe/query capability would really enhance ParaView as a tool for understanding quantitative spatial data.
7 votesThis is already supported, for the most part.

Fix, and maintain, the Mac "make install"
For 3.6.0 the Mac install from cvs worked, namely the process ccmake, make, make install. I had been waiting for that for years, and was quite happy when it finally worked. But apparently it was not maintained from 3.6.0 to 3.6.2, because now it doesn't work. The worst part is that the GUI comes up and seems to function but generally crashes very quickly. There is no indication that the problem is with the install.

Reload-Button
It would be nice to have a reload-button for time-dependend datasets. So you don't have to apply all your filters again if the simulation is evolved in time.
308 votesThis feature is now available in the development repository and will be included in the next release, ParaView 5.2.
See the merge-request (now merged) for details: https://gitlab.kitware.com/paraview/paraview/merge_requests/1000

Add vector graphics output (i.e. postscript)
Users have wanted this for at least 5 years (see http://www.paraview.org/pipermail/paraview/2004-September/000836.html), and it was never done. There is a user-made patch by Christian Becker that has been in Mantis for two years (see http://public.kitware.com/Bug/bug_view_page.php?bug_id=2887).
256 votesThis is now in ParaView 4.0. Please send comments

Non-rectangular selection
It would be nice to draw a non-rectangular shape and do something equivalent of "select cells through" - where the region you draw is back projected "infinitely" and anything in the projection is selected? (Equivalent to the "free select tool" or "lasso" tool in GIMP) I'm finding it very hard to select some regions of a 3d model only using rectangles!
16 votesParaView 4.0 will support selecting arbitrary regions. (Changes are already in ParaView git repository).

Add copy and paste properties (or clone filter)
When working in large pipelines, it's common to copy some filter properties between different instances. It would be very handy if there was a copy and paste or, maybe, a clone filter.
54 votescommit abd9d370af75477456e226855a3f84e5a407e669
Added support to copy properties. Simply right click on a source or use the “Copy Properties” action from the Edit menu.

Add ability to use LaTeX in text and axis text
Add ability of using LaTeX to input text into paraview, as legends or in axis.
205 votesAlthough not LaTeX, Mathtext (http://matplotlib.org/users/mathtext.html) is now supported in ParaView (starting with 3.98.1). To use mathtext in text or 2D axis labels, simply enclose the expression in $..$ markers e.g. $a^2$

Orient cylinder glyp direction using vector
I would like to be able to orient the cylinder glyph direction using a vector field.
11 voteshttp://paraview.org/Bug/view.php?id=9329
This will be fixed in 3.8.1. Has already been fixed in development.
To orient cylinders, simply set the “Glyph Transform” “Rotate” value to (0, 0, 90).

improve data format documentation
Data format documentation is available through ONE document only, the slighlty outdated article "File Formats for VTK Version 4.2". I spent money on the paraview guide, but also nothing there. Paraview is a great program, but the documentation situation is absurd! Please help!!
