  1. 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)

  2. Alpha blending or opacity by data value

    It would be great to set the opacity by a certain data value or set an alpha blending respectively.
    E.g. you have a 3D object with a discrete density distribution. The density is illustrated by color. Every density value was determined with a certain accuracy. Now it would be great to illustrate cells with good accuracy opaque and cells will fade more and more by increasing errors.

  3. 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.

  4. openfoam

    The standard release of Paraview can read binary double precision OpenFOAM cases. It would be very useful if it could read binary and ascii and single and double precision natively. If it could autodetect the format and precision when reading the data in, this would also be extremely useful.

  5. Add interpolator type (cell locator) to stream tracer with custom source

    Stream lines often break with point locator (default) of stream tracer with unstructured vtu data. One solution is to choose cell locator instead of point locator. But "stream tracer with custom source", which includes all flexibility to choose source points, does not have these options to choose.

  6. Improve the CGNS reader to reduce loading time

    Improve the CGNS reader to reduce loading time of large datasets. This would be useful for post-processing large datasets in all applications such as CFD where the CGNS format is widely used.

    With a medium size 1.4 Gb CGNS dataset, Tecplot loading time is about 15 times less than the loading time of the VisIt CGNS reader in PV 4.0.1.

  7. improve usability of LOD actors

    LOD actor goes back to full representation on mouse release. In ICEM_CFD it waits 2sec (or so so) so I can continue transformations in LOD mode without annoying delays. It is very smart of them and such feature should be added to VTK/PV.

    This has now been fixed in git-master. There’s a 2 sec delay. It will make it into 3.10 release.

    commit 8be56b840924502ca8a93328bb5986e9bfd43da6
    Author: Utkarsh Ayachit
    Date: Sun Jun 20 16:38:58 2010 -0400

    Added support to persist LOD mode when interactive. Fixed BUG #10232. The interactor now switched back to full-res after 2 secs of timeout.

  8. Add the ability to threshold, contour or clip by vectors (magnitude or component)

    It would be really nice to add the ability to threshold, contour or clip by scalar using variables other than scalars. Magnitude, and one of the components of a vector come to mind.

    There;s also an option named “Auto Convert Properties” in the Settings dialog that can be turned on to “automatically” extract components or compute magnitude for field arrays.

  9. 05.2009 Coming Soon: ParaView 3.6 ... why does soon take so long?

    ParaVew is a great program we all thank you for doing such a great job. And we would be even more pleased if soon is really soon ...

  11. Hide the Output Messages window

    Hello,

    I find it a bit annoying that the "Output Messages" window pops up every time I do something in Paraview. I've dug around in menus and settings and there seems to be no obvious way of disabling it.

    I would prefer it to stay closed when I press "close", or at least not have it always on top of the UI. Most of the time, things are working well and I don't need to see the information in this window. I just want to look at my data.

    Example of output :

    Registered event listener change listener: true
    FIXME:…

  13. 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!

  15. buid a filter able to selectively rename/delete arrays from a dataset

    Sometime after extensive calculations you end up with several point/cell data arrays that are useless and just take memory like IDs, Region ID etc It would be nice to be able to rename/delete these from the current dataset and spare memory

  17. 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

  19. Temporal Derivative Filter

    I'd like to have a filter that calculates the difference of my data (point data, cell data, etc.) compared to the previous time step, i.e. the time derivative of my data.
