  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)

  3. green dot marking the current time for parametric plots

    In a PlotSelectionOverTime filter, the resulting 2D plot can be shown as a function y = y( timestep ). This is the default, and by default a very handy vertical green line marks the current timestep.

    The plot can also show parametric graphs, where (x,y) is plotted, and x = x( timestep) as well as y = y( timestep ).

    In this latter case, I would like to see a green dot marking the (x,y) of the current timestep.

  4. Parrallel Data Volume Rendering

    Paraview is supposed to be good at parallel task. But I don't understand why when I use a *.pvd file to load a parallel dataset consisting of several Rectilinear blocks, with volume rendering Paraview only renders only one of the blocks at a time and not all of dataset. It is good to have this resolved because I think volume rendering is one of the Paraviews interesting features.

  5. Add linear extrusion in surface normal direction

    The Linear Extrusion filter allows fixed extrusion directions only (x,y,z). It seems to me that adding an option to use the surface normals instead is an easy task, and will be useful in many cases. Possibly, the scale factor (surface thickness) could even be a scalar field, which would make this filter even more useful.

  6. varying timestep size for .vtk format files

    As suggested here,
    http://www.paraview.org/pipermail/paraview/2011-May/021348.html
    I propose supporting varying timestep for .vtk format files
    via the vtk index.

  7. Glyphs: Scale only the arrow length instead of the whole glyph size

    The glyph filter has the nice property which allows to scale the glyph. However, for all arrow glyphs, a better way of scaling would be to scale only the length of the arrow by a quantity instead of the whole arrow (shaft and tip thickness). This simply gives a much clearer overview if there are regions with big and small arrows in one domain.

  8. Science on a Sphere

    Dear paraview product managers,

    i would like to point yours to a new awesome displaying technology named Science On a Sphere in short SoS which was invented at NOAA (http://sos.noaa.gov/What_is_SOS/index.html)

    images or video frames should have the following parameters
    - aspect ratio is 2:1
    - prefered resolution 4096x2048 or higher
    - JPEG or PNG for single images and image sequences
    - Map Projection – Equatorial Cylindrical Equidistant Projection. This is a simple latitude/longitude grid where the image is twice as wide as it is tall.

    Will be great to be able to export single image or an image…

  11. Temporal statistics

    When you switch off a range of time steps, the temporal statistics no longer works. I have to manually alter the .xmf file so as to only average the time interval I want. Is there a way I can do this without the manual editing of the files? ie is there a way to pick a range of time intervals or not loading a range of time intervals.

  12. 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.

  13. 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!!

  15. 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. bug - Calculator

    I've noticed that in Paraview 3.14 and 3.10 in linux the calculator scalars menu does not allow you to choose for example the velocity components while the above data source is visible (eye on) while when the source is invisible than the scalars can be chosen. This does not occur when using the Windows versions.

  17. Master clip filter for entire scene

    I would be nice to have some form of a master clip filter for the entire scene. This must not generate new data/geometry; it needs simply hide what is outside the box widget control. This is useful because in mining/geology/etc. we often work with sections, without modification of data.

  18. 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

  19. Add integration/trigger between the animation feature and Exporter plugin

    There are occasions where the viewport/OpenGL render of a data set lacks the visual fidelity due to available/accessible hardware for a reasonable turn around time. The above integration will enable offline film quality render at arbitrary resolution, independent of the viewport hardware. One immediate use case is the export of an animation via the existing POV exporter for offline rendering with POVRay.
