  1. Extract the index from selected points, in the order they are selected and extract plane parameters from slice

    Hi, I would like to extract the index of the points selected in the order I selected them. But when I choose extract selection and save the csv file, I get them ordered from small to big. Also I would like to save the point coordiantes and his normal when I choose slice. I see them in the box in the left, but there is no option to save them in a csv file. Thanks

  2. Develop an Ansys reader

    I can not read my Ansys Structural case data in ParaView. I think it would be a great idea post-process Ansys Structural in Paraview.

  3. 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?

  4. default .med plugin

    open source FE solver of code aster doesn't have post processing tool with it and default output format is (.med) . it's available in paravize but that require separate coupling so it's better to have .med plugin with para view

  5. 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

  6. Show more information about each block in Multi-Block Inspector

    I would like to visualize specific parts of large, multi-block datasets using the Multi-Block Inspector. Currently I rely on a Python script to extract each block. This Python script gets slower as the number of blocks in the dataset grows. The Multi-block Inspector would solve this problem if I could match my name for the blocks to the block indices conveniently.

  7. When loading saved state remember settings

    When loading saved state remember if (for instance, when having slice) if "view plane" is selected or not.

  8. Drag and Drop for states and plugins

    Paraview can handle drag and drop for data files (great feature) but not for state files.
    Also make drag and drop working for plugins. (copy the plugin file to some safe place .config/... and check the Auto Load). This can make using plugins much easier for new people.

    And have a central place (wiki maybe) with a list of the community plugins (compiled or in source).

    Great job and Merry Christmas to all.

  9. Support for a spherocylindrical particle (capsule shape)

    Context: Lagrangian simulations of capsules. (DPM)

    Lets say we have data for the orientation vector, position vector, length of shaft and the radius of a spherocylinder for each timestep. Then it should be possible to visualize this particle behaviour with time in Paraview.

    DPM modelling for non-spherical particles is the next upcoming field and currently no visualization package supports non-spherical particles. If this feature is released for Paraview, I am sure the user base will grow manifold.

    Thanks and regards,
    Vinay

  10. Add a low-pass buttworth filter, FFT and inverse FFT filter for tabular datasets

    If your trying to get acceleration from any explicit FEA a small amount of filtering to the data must be done. Ideally, I would like to run an FFT, truncate the signal to only include low frequency content then run an inverse FFT. I would also like a butterworth low-pass (high order 16-10) filter in order to have a comparison of each method. I believe this is all available for images but not tabular data.

  12. 360 equi-rectangular option for camera to view with cheap VR Glasses

    It would be fantastic to provide an option to output a 360 screenshot or video using equirectangular projection.. or even direct scrren output so it may be streamed to smartphone in VR glasses and give CAVE like experience to the masses.
    It is yet possible to do this by making 4 videos with 100deg FOV and stitch them with "3D Stitching" software post-processing giving output like :
    https://www.youtube.com/watch?v=dwKanld6MFE but right out of paraview would be fantastic

  13. support for gzipped nrrd files

    We and our colleagues (working in fly brain neuroanatomy) use the NRRD format. We have >100,000 NRRD images with data gzip encoded. gzip compression is useful because many images are sparse and compress by factors of >10 or even >100x.

    At least on the current v5.4.1 on mac gzip encoding is not supported.

  14. 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.

  15. Prepare a pipeline with multiple filters, then apply

    When dealing with large datasets, it would be nice to be able to prepare the pipeline with multiple filters (calculators, isocontours, plane) and then do the postprocessing and rendering, instead of having to create a filter, apply, create another filter.

  17. Create a conda binary distribution

    This will make easy to install paraview in any platform with a single command line:

    $conda install paraview

  18. Glyph Type text

    The (now rather ancient) visualization software OpenDX has the ability to show glyphs in text form. This glyphs represent the point values as a text string. The text glyph could be 2D (always oriented in the view plane) or 3D. I am aware that text values at a given position can be displayed using the labels of the selection display inspector. But this options needs a lot of user interaction and it seems not to be possible to compare the values of two different objects.

    Extending Glyphs to have a text representation would be very much apreciated.

  19. Ability to change data file without having to disconnect and reload state

    When you load a state, you have the option to change the data file used. It would be nice if when you have loaded a state, you could right click the data file in the pipeline browser to select another data file (or alternatively, change the file name property in the pipeline, or drag and drop a file into its place).

    This would save time when you have many data files in the same format to visually inspect, for example many runs of the same experiment under various different conditions.
