  1. 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…

  2. 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.

  3. 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).

  4. 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.

  5. 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.

  6. 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.

  7. 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

  8. Don't hang the client during Filter/Reader/Writer execution

    It would be nice if the user could still use the UI while the servers are working.

    Corollary: Progress bars!

  9. 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.

  10. 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!!

  11. 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…

  12. 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.

  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

  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.

  17. Add a tick level property to the Cube Axis Annotation

    It would be nice to be able to define the spacing between ticks, instead of only have the default values.

  18. Modify the transform filter to allow single-axis-at-a-time transformations

    In some modeling software, when you are in transform mode (ie the transform filter) you can select a particular axis to translate/rotate about by pressing 'x', 'y', or 'z' before performing the operation. It is very hard to position an object in 3d without that ability. Maybe by clicking the "balls" at the end of the transform axes with different buttons you could specify that functionality.

  19. Ellipsoids source/glyphs

    It would be nice to have the ability to draw ellipsoids or specify a major/minor axis at each point and glyph an ellipse at each point using those axes.

    There is a feature request for an ellipsoid source here:

  20. 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
