  1. Add to the calc'r filter a running min/max function

    In a transient calculation it can be informative to see the maximum (minimum) value at a point (cell) up to the present time.

  2. Table to X filters should support 2D data

    The table to points and tabled to structured data require separate columns for x, y, and z coordinates. However, sometimes you are only representing 2D data (or even perhaps 1D data). It should be possible set any of the X, Y, Z Columns to something like "None" so that that coordinate is just filled with 0's.

  3. Add setting to change your default volume fraction for imported volume arrays.

    When importing spcth databases from CTH into paraview, the "Extract CTH Parts" filter is used to extract each material. The default volume fraction is set to 0.1, but I generally need mine to be at 0.5. It would be great to have an option to manually set the default volume fraction so that that step of adjusting the volume fraction for each material could be eliminated for most cases.

  5. boolean operations

    add boolean operations between several meshes. Not only append, but really intersection, union, difference.

  6. Screenshot in fullscreen mode

    I'd like to do a screenshot in fullscreen. At the moment, this is a bit tedious: I have to use two screens. On the 2nd monitor, a Phyton shell can be opened, and while displaying the picture on the 1st monitor, I can enter the "WriteImage" command in the Phyton shell.

    Ok, that works, but I think, there must be a simpler solution. What about connecting the screenshot menu item with a keyboard shortcut, so it can be activated any time?

  7. Stereo mode for FPR (film pattern retard) passive stereo 3D TV (LG's)?

    What stereo mode should I use to display on FPR (film pattern retard) passive stereo 3D TV (LG's)? I've tried every --stereo-type with 3.10.1 but could not find.

  8. Add B-Spline/ NURBS visualization capability.

    Direct visualization of NURBS --no discretization necessary!. NURBS is already a standard in computer graphics and the future of FEA (isogeometric analysis).

  9. being able to save selection.

    it would be extremely useful to being able to save a selection, either in a separate file or in the current state. also the order of the selection should remain the same.

  10. Hi. Could you post some recommended hardware configurations?

    It would be really useful to know how to divide up a £2K/£4K/£6K spend on a workstation optimized for paraview 3D rendering - is it worth spending on lots of multi-core CPUs? Lots of RAM presumably - is it worth spending ~£3K on a CAD level GPU with 6GB of memory? There doesn't appear to be much easy to access info on this on the web (maybe buried somewhere)....

  11. Modernize VMRL and OBJ readers

    VRML reader should support aliased materials, OBJ reader should support MTL files (suggested by David E DeMarle)

  12. create the ability to automatically label contour lines when creating contour plots

    I'm trying to place engine exhuasts on a car and need to identify regions of certain pressure. Solid colours are too blurred to define precisely such regions. Contour plots are great for this but need automatic labelling as an option

  13. embed a thumbnail in state files for preview

    embed a thumbnail screen capture that was taken at the time state was saved. Then use this embedded image in the file open dialog as a preview.

  14. report progress during state loading

    Loading from state with complex pipelines on client server mode takes a LONG time. much longer than an end to end update of the same pipeline. When there are multiple views involved it's exponentially longer. During this time there is absolutely no indication of whats going on, progress is not reported. PV should report the progress of each filter as state is loaded.

  15. Extend FileSeriesReaderProxy for files named by Date & Time

    Extend ParaView's FileSeriesReaderProxy to step through files named by date & time rather than by integers in a filename.

    This documentation explains how to use FileSeriesReaderProxy to animte over files named foo1.xyz, foo2.xyz, ... fooN.xyz.
    http://paraview.org/Wiki/Animating_legacy_VTK_file_series

    However, this doesn't work with filesnamed by date and time (Year-Month-Day-Hour-Minute-Second):
    foo_1995-03-21T00-00-00.xyz
    foo_1995-03-21T01-00-00.xyz
    ...
    foo_1995-03-21T23-00-00.xyz
    foo_1995-03-22T00-00-00.xyz
    ...

    Inspired from discussions on the mailing list http://www.paraview.org/pipermail/paraview/2010-December/019663.html

  16. Add a ability to select nearest point...

    Would be a nice feature to select a point in the data not only with the rubber-band but with a modus "next point". This means, clicking on a surface an hold e.g. <cntl> the nearest point relative to the cursor is selected.

  17. Add a ruler tool to calculate distances between 2 points on surfaces in the 3D geometry view

    It is often useful to check distance between parts of a 3D geometry you are viewing and processing. This could be achieved with a ruler tool That would give not only the distance magnitude between two points, but also x, y and z distances.

  19. edge elements

    Right now quantities are associated to nodes or elements, but in electromagnetics some quantities are naturally associated to faces (fluxes) or edges (magnetomotive forces) and special finite elements (nedelec / raviart-thomas) can be used to interpolate such quantities. Is support for such entities planned? If not how difficult would it be to implement it?

  20. provide some kind of global variable definition

    Often I'd like to have a "global variable", so that I can change a value at only one position, which is referenced by several filters, including Python programmable filters/sources.
    The smartest thing would be, to have a slider widget, with which I could interactively change the value of this variable and so could examine different stages/points of view/slices... (depends on how I used the variable) of the dataset.
