Re: [Paraview] Saving pipeline object data as a .csv
The ExodusII reader produces a multiblock dataset that can have empty blocks. As a result, those empty blocks get saved as blank csv files. You can apply the ExtractBlock filter to only pass through blocks of interest and then save that result, instead.

Most of them will be blank. For example, with a mesh file with 339645 elements, will save a file MeshData1k.csv in increments of 37116 for k = 0,1,2,3,...,9. It will also save 90 blank files afterwards. I would simply concatenate the tables but I have mesh files of radically different geometries and materials blocks that I need to script; these end up having different total mesh elements so the k range will not be the same and the blank files also differ.

Re: [Paraview] volume color transfer table.
To the best of my knowledge, the current volume mappers in VTK/ParaView need to use a color/opacity transfer functions. Aashish, is that changing with the new volume rendering code?

If tried different settings, but nothing really works. If i make a tick at rasterize 3D geometry the exported pdf also occurs an error and the shown graphic is kind of a bitmap graphic and not a real vector graphic like I need. You are rigth it isn´t grey-colored anymore. The errorin adobe acrobat reader is like: The graphic could not be presented correctly, please contact the producer of the file. We use an external library to produce the exports (gl2ps), and this is a limitation on their side -- the textures that are used to color the data cannot be detected by gl2ps, so the only way to get the colors to appear is to rasterize the data. Indeed, this defeats the purpose of using a vector format :-( There was a similar issue on the developer's list a few months ago, see this thread: http://public.kitware.com/pipermail/paraview/2014-February/030639.html Is there a Interpolate Scalars Before Mapping option enabled in the paraview properties panel? Disabling that will change how the colors are stored, and seems to work around the texture issue. As for the client error, that's hard to track down without seeing the file. By chance, do you have any multi-line text being rendered in your scene? There was a bug (fixed in the development version now) that would cause similar problems when exporting multiline text as a path. Is it possible that the problem depends on the code I use to convert my simulation results into a inp-file to visualize with Paraview. In Paraview I don´t get any errors and problems and everything works still fine, but maybe I have forgotten to add some kind of special code? Not likely. GL2PS works by watching the OpenGL feedback buffer -- basically, it watches what is being drawn in the window and converts it into a vector format. This is independent of the original data format.

[Paraview] multiple files with different geometries
Hi, I want to see the data of two .vtk files in Paraview. One of the file is surface data (topography from SRTM, 45 000 points polydata) and the other one is a kernel file (20 millions points unstructured grid). I want the surface data on top of my kernel data. I can see each of them separately but not together. I thought it was due to their different geometries (x y z range) and I have applied a transform filter to translate the surface data but still, I cannot see the two dataset together: when I put Visible 'on' for the kernel data, my surface data disappears.. How can I deal with that? thank you, Julie ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Follow this link to subscribe/unsubscribe: http://public.kitware.com/mailman/listinfo/paraview
Re: [Paraview] volume color transfer table.
thanks for the attention! I should also point out that i have tried the import/export options on the color table editing feature- opacity is not preserved. i.e. when i export a table to an xml file, the opacities all revert to 1.0, and when i import an xml file, any ' o=x.xx ' value is ignored, and whatever opacity function in the editor from previous work is applied instead. cheers- -lawrence a.

Re: [Paraview] volume color transfer table.
that is indeed annoying, and would be very nice to be able to save the opacity table. A work around is use a state file.
