[Paraview] proper formatting of 2D data
Hi, I tried to visualize 2D structured point data when I observed a strange behavior. If the spacing in Y direction is negative, the data is flipped upside-down in 'Slice' representation mode but shown properly as a 'Surface' representation. Tried in v. 4.0.1 and 4.2rc1 on Linux 64 bit. Here is a small VTK file to test: --8-- # vtk DataFile Version 2.0 testing ASCII DATASET STRUCTURED_POINTS DIMENSIONS 3 4 1 ORIGIN 0.0 0.0 0.0 SPACING 0.5 -0.75 1.0 POINT_DATA 12 SCALARS test float LOOKUP_TABLE default 0.0 1.0 2.0 1.0 2.0 3.0 2.0 3.0 4.0 3.0 4.0 5.0 --8-- I am wondering if I missed something when formatting the file or if you have any ideas how to avoid this behavior?

Re: [Paraview] Client server volume rendering problem in 4.1 and 4.2RC1
Hi Utkarsh, I have just downloaded the latest nightly build and it seems to work fine now (on Windows 7/64bit), doing remote volume rendering irrespective of the settings for remote/local. Many thanks for that quick fix.

I has been on my todo list to clean up the remote-local rendering issue. I want ParaView to automatically switch to remote rendering, if possible when volume rendering. I'll see what I can do for that. The volume rendering code is currently being revamped. I'd expect better smart rendering in near future. Utkarsh On Wed, Sep 17, 2014 at 6:29 AM, ronald.fow...@stfc.ac.uk wrote: Hi, A post by Robert Atwood in June mentioned a problem with client server volume visualisation in PV4.1, and I have also seen problems in this case both on Linux and Windows systems. Fixes (0014794 and 0014792) have been added to 4.2RC1 which allow correct rendering of the wavelet test case. I tried this on a Windows 7 system and works ok for 4.2RC1, but not for 4.1. However I think that the remote/local render problem for volume visualisation is really very confusing and needs to be improved. After spending more time then I should with it, I conclude that (again on windows 7 64 bit): (1)Volume rendering only works if done on the remote server, not the local on (as acknowledged in a tracker ticket, though I have not seen it documented elsewhere). (2)For 4.1 to do this correctly for just a volume image this seems to need settings of “remote render threshold” ticked and “0 Mbytes” selected. It will work for cases when 0 Mbytes is selected, if there is also another object displayed (e.g. an isosurface). This led me to think an additional surface was always needed to see the volume, which is not the case. (3)For 4.2RC1 the interface to settings has changed and there is no longer a tick box. Instead the slider for remote local render size has a much greater range. This should be set to zero to force remote render for volume views. It also works for non-zero values less than the size of the volume data, e.g. 4Mbytes for a 256^3 volume. This setting did not seem work for 4.1 to force a remote rendering of just volume data. I think it would be useful if at least the tool tips in the settings panel suggested how to make client server volume rendering work. It would also be useful if a warning message were displayed when trying (and failing) to do a local volume render in client server mode. Another problem that has been observed is that the “smart” option for volume rendering is not necessarily that smart when the server nodes have no GPUs and the client does. This was on a Linux 64 bit system with 4.1.

[Paraview] 3D contour smoothness
Hello everyone, after extensive search I was desperate enough to post on this list: It appears that the surface smoothing algorithm of the contour filter does not work as aggressive as in older version (3.14.1 was the last one we found to do so). As an example I prepared this two screenshots, VTK data are scalars on a structured grid (200x100x100), legacy format. (An additional call of the smooth filter does not help.) 3.14.1 http://s7.directupload.net/images/140919/euadfvko.png 4.0.RC1 http://s14.directupload.net/images/140919/84y689mi.png Both versions are running with the shipped settings. Since the effect could be reproduced on several workstations, we are wondering whether there has been an (undocumented?) change in the filter mechanism or some option we/setting/data problem we are not aware of. Kind regards and thanks in advance Philipp Engels. ___ 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

Is negative spacing really supported in VTK/ParaView?

The data set is pressure, contour value is 0.55. By looking again at the data (contour - information), I just found that the old version (3.14.1) uses 148432 cells , while the the new one employs 75232 cells. Hope that helps.

As an example I prepared this two screenshots, VTK data are scalars on a structured grid (200x100x100), legacy format. (An additional call of the smooth filter does not help.) 3.14.1 http://s7.directupload.net/images/140919/euadfvko.png 4.0.RC1 http://s14.directupload.net/images/140919/84y689mi.png Both versions are running with the shipped settings. Since the effect could be reproduced on several workstations, we are wondering whether there has been an (undocumented?) change in the filter mechanism or some option we/setting/data problem we are not aware of.

Re: [Paraview] How to simply Reload a data file
We use this simple python script for file series (stl, vtk, particle data in LAMMPS text- or binary format (with our own reader)). Feel free to use this as a starting point: https://github.com/richti83/ParaView_Reader_for_LIGGGHTS/blob/master/python_macros/update.py The if-condition in line 68 should be more generous, but for now it works and you can add every source (plane,line,...) there which does not support file series. To use it: first build your tree in the pipeline browser by opening file series (need to have more than one file bc. otherwise the reader_core is used inside PV instead of PV_FileSeriesReader). Than, while the simulation is running, just hit update macro button to reload the file series and jump to the last available timestep. Best, Christian.

To understand this better, what is that which is changing that you need to reload the file? Are you loading a file series or a single file?

As for the XML method, did you try to load an Xdmf file through what should be the new Xdmf Reader (Refresh button) reader? If you are loading a different type of file, this plugin will have no effect because it provides a Refresh button only for the Xdmf reader. You could modify the XML for other reader types, though.
