  1. Create an XML file syntax checker

    A script to check simple things like if the class the plugin is using actually exists and if the functions that are supposed to be called actually exist. It would be nice to know these things before errors occur at runtime :)

  2. legend layout improvements

    it would be nice having
    - line-break / feed in legend headers, e.g. for displaying the unit in a second line
    - ability to remove the display of the highest and lowest values (which are always there and they are not aligned with the other values)
    - Ability to choose the labels, much like the "new value" / "new range" buttons of the slice filter

    instead having an option

  3. Persistent selection tool (and type) with auto use & execute

    When probing a data set it would be nice to have an option where the selection tool stays active, and the pipeline knows to automatically use new selections after they're created and execute the pipeline.

    Unless you're just using cell and point labels, a typical current process is to select, extract and add some further pipeline (e.g. statistics, particle pathlines...). The main problem comes when you want to probe a different piece of the data: you need to go back and choose the selection tool again and make a new selection (and maybe go to the Selection Browser and change…

  4. Add carpet plot view

    This view should take a 2D dataset and render it as a carpet plot using a custom mapper to avoid the memory cost of converting it to polydata and warping it. It should also have decent x-y-z axis.

  5. Easier to use Plane Source

    The plane source seems very awkward to use - specifying three corners of the plane. A more natural way to specify a plane is by the origin and normal vector. A radius would also be needed to specify how large the patch of the plane should be. Maybe a "Square Sphere Source" source could be added on top of the existing Sphere Source so people can use the existing one for "difficult" planes (non-rectangular) and the new one for "easy" planes (square).

  6. Add a combo-box in the DisplayPanel for Composite/MIP/MinIP mode of the Volume mapper

    I changed the XML (rendering.xml) by adding a SetBlendMode property, with 3 values:
    - Composite
    - Maximum intensity
    - Minimum intensity
    default_value allows to choose one of the 3, but have to recompile paraview. The blend mode cannot be changed from the PV interface.

  7. Add an auto-redraw option.

    Currently, ParaView automatically re-renders the screen after any filters have been applied, which can cause large delays if datasets are large and representations are set to anything but outline. It would be nice to have an auto-redraw tickbox option with a redraw(render) button on the UI, so that the user can apply any filters and render whenever they want manually by button clicks. A similar effect can be achieved using representations, but the drop-down box can prove fiddly if it has to be changed frequently.

  8. Include a 'Save State & Data' option.

    It would be very useful if an option was available so that the user could save his/her current state, commands and data (including any new variables) inclusive within a single file. This would provide a unified, compressed dataset that is independent of platform being used to visualise it, not only making it portable but the user would not have to worry about the paths to the dataset and it could act as an emergency backup for the data. As far as I am aware, both Tecplot (*lpk) and Ensight have this feature available.

  9. Enable caching of (static) meshes for transient data

    Following on from:

    http://markmail.org/message/b3ro3hvuqqenxyfg
    • for transient cases employing static meshes, provide a mechanism to cache the mesh so that it is not necessary to rebuild the complete visualization pipeline

  11. When using several windows, add ability to resize them all to the same dimensions

    Sometimes I use several windows to visualize diferent quantities in a flow. I would wish to have a button or check box so the windows would share the same dimensions. It is like the "Link camera" but for the windows dimensions.

  12. automatically adjust point/line sizes for screenshots with different resolution

    If you have points or lines in the scene and you take a screen shot at a higher resolution than the current window (say 5000x5000), many of the objects stay the same size (spheres, planes, triangulated meshes) but many objects get much smaller (points, lines). Surely this is because the points and lines are specified in arbitrary units (Point Size = 3, Line Width=2, for example). An example is here:
    http://rpi.edu/~doriad/Paraview_List/linesize.jpg

    Notice the lines in the screenshot are much thinner.

    It would be nice to have theses sizes automatically adjusted to the relative difference between the screenshot size and the…

  13. Abort filters and rendering without having to quit paraview (Bug 3925)

    Some filters can take very long to finish. Also large datasets might take forever to render. It would be great if a user could press a stop button to stop these processes without having to kill paraview.

  16. support reading and writing point data in a simple binary XYZ or XYZ-Scalar format.

    Paraview already supports many different file formats, but from what I can tell, these all relate to other 3rd party programs. It would be very useful if paraview could read and write to files with a simple binary format, such as a contiguous block of doubles or floats <x1><y1><z1><scalar1><x2><y2>...
    This would make integration in to custom apps much easier.

  18. integrate variables bug fix

    a) have a field with constant values all over the field
    b) define a slice (rectangle)
    c) integrate this variable
    d) divide the values by the area of the slice
    e) Expectation: get the average value which is the constant BUT paraview gave me a value of 25 % wrong

  20. Limit precision in GUI text edits

    Right now the text boxes in the GUI can display numbers of pretty much any precision. Although in general this is a good thing, it get really annoying if the boxes are displaying numbers with too much precision to fit in the text box. For example, if you rotate the camera with the mouse and then go the the Adjust Camera dialog, all the text boxes under Camaera Positions have a crazy amount of precision that makes it impossible to really read the numbers and hard to edit them. This happens in many other places in the GUI such as…
