Re: [Paraview] [EXTERNAL] Geometric center of Dataset
If you are looking for the Centroid of the dataset, then I would propose 3 lines of python in a Programmable Filter, using numpy's mean. Cut and paste in the script section of a PF: from paraview.vtk.dataset_adapter import numpyTovtkDataArray coords = inputs[0].Points print mean(coords) see page 85 of the ParaViewManual for other examples http://www.paraview.org/files/v3.98/ParaViewManual.v3.98.pdf - Jean CSCS ___ 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://www.paraview.org/mailman/listinfo/paraview
[Paraview] Failed to locate server for newly registered proxy ( animation , AnimationScene2 )
Hi, I've been having an intermittent failures initiating connections to remove servers. That is, I have successfully used paraview in cliient/server mode many times but also had many connection failures. All I get is the error: Failed to locate server for newly registered proxy ( animation , AnimationScene2 ) It shows up after I select the server configuration and click connect (i.e. when it would normally be ssh'ing to the server). Ssh works and I have no trouble connecting to the servers manually with ssh. Paraview crashes after the error message is printed. Sometimes after 3 or 4 failures(restarting paraview each time), the connection will succeed. I'm attaching the servers files. This happens with paraview 3.14.1 and 3.14.0, on mac os x 10.8 and ubuntu 12.10, and on commercial broadband and gigabit ethernet connections. I am using kitware paraview binaries on the client, while the server binaries match those versions and were built by sys admins. Unfortunately we don't have paraview 3.98 installed on the servers yet so I can't test the latest. The configurations I'm using out of the list are 'garnet', 'diamond', and ERDC Utility Server. Same error for all configurations at about the same frequency. Any ideas?

Re: [Paraview] Quadrature in Paraview
Hi afad sfgsfdgsfd, Fixes for bugs introduced by changes in VTK's xml file format are in the pipeline, so you'll have to checkout the latest git HEAD and build ParaView from source to get the bug fixes. If that's something you're willing to do, here are first steps # get sources $ git clone --recursive git://www.paraview.org/ParaView.git # apply the patch # patch is attached and I just now submitted to PV, will show up in PV after the next review. $ cd ParaView $ git am -3 0001-QuadraturePoints-any-integer-type-for-offsets.patch # build pv That will get you the bug fixes. Build it, use default build opts is fine. Then if you like you can get the test data, and open the file ParaViewData/Data/blow.vtk, construct the pipeline showed in the post (http://markmail.org/message/6qz3ebszvny4vwxp#query:+page:1+mid:6qz3ebszvny4vwxp+state:results). That shows how it's supposed to work. $ git clone www.paraview.org/ParaViewData.git Now onto your data, the xml you gave is incorrect , it's missing the offset array. let me see if I can get your example working, I'll post a follow up, hopefully in a few minutes.

Re: [Paraview] Line thickness vector image
Hi Nikolay, The new GL2PS line and point scaling factor branch has been merged into ParaView's master branch today. The easiest way to use the feature is to go to File Export Scene and select one of the vector graphics formats (ps, eps, svg, or pdf), and the configuration dialog that pops up will let you toggle the scaling factors. The default value is 5/7, like it was before. If you want to continue using your script, the mechanism is a little different. Rather than calling the global functions to set the scaling factors, the factors are now a property of the vtkGL2PSExporter instance with their own setters/getters. They will need to be set for each vtkGL2PSExporter used. Let me know if you have any problems with the feature or notice any regressions with the new implementation.

Re: [Paraview] Time series of files with different dimensions
Hi Jiri, Unfortunately, this particular feature is not currently supported in ParaView. There are various reasons behind this and it is too complex to explain here. You can get around this however. You can create a multi-block dataset (a vtm file) that points to the rectilinear grid. Too see what this looks like, apply Group Dataset filter to your data and save it out as a vtm file. This should generate a vtm file and a vtr (or vti if this is uniform rectilinear grid) file. You can file more information about the vtr format here: http://www.vtk.org/VTK/img/file-formats.pdf Best, -berk On Thu, Mar 28, 2013 at 5:01 PM, Jiri Vyskocil s...@centrum.cz wrote: Hello, I have a series of ASCII VTK files with 3D uniform rectilinear grid data. Each file has different dimensions - one cooridnate (x) grows in time. Let's say the first file is 4x9x9, next is 5x9x9 ... up to 100x9x9. When I load the files separately, they display correctly, but if i load them as a time series together (from the file chooser, grouped by timestep number). They are all rendered only as big as the first file (4x9x9). If i step through time, the Bounds and Extents on the Information tab show correct values - the x coordinate is growing. But in the rendering window will only show a 4x9x9 box for all files. I use a 3D view with slice representation, but even the Outline stays small. Today, I accidentaly managed to open one of the series, while still having another file open, and suddenly it displayed correctly - the dimensionsof the rendered graph were the actual dimensions as displayed in the information tab, so it should be possible to do this - but I have no idea, how I did it. Is there some option to make ParaView update the dimensions for each file in the series? I'm using ParaView 3.98.1, Linux, 64-bit. I attache some sample files, in case it would help.
