Link library in ParaView plugin CMakeLists.txt

◇◆丶佛笑我妖孽 提交于 2019-12-25 06:43:47
问题 Recently I've been trying to write a plugin for ParaView and I have encountered a problem while trying to link external libraries. First of all I must say that the compilation goes fine but I get an error at runtime saying the dreaded words: "symbol lookup error .. undefined symbol". When using ldd on the file that I load into ParaView, none of the vxl library files that are required for this plugin are listed. ParaView has it's own weird way of defining plugins in the CmakeLists.txt file and

问题 I am trying to load multiple state files by running a python script with python shell. The script is the following #### import the simple module from the paraview from paraview.simple import * for time in range(0,200): renderView1 = GetActiveViewOrCreate('RenderView') # destroy renderView1 Delete(renderView1) del renderView1 filename = 'filepath/filename-%s.pvsm' % time servermanager.LoadState(filename) renderView=SetActiveView(GetRenderView()) Render() # get layout viewLayout = GetLayout() #

create multiple polylines given a set of points using vtk

问题 I need to display the trajectories in space of 50 particles using vtk and paraview. Currently my data is pos(x,y,t,n) where n is the label of the n-th particle. I have saved all my data in a vtk file which is organized as: # vtk DataFile Version 3.0 VTK from Matlab BINARY DATASET POLYDATA POINTS 199250 double [PROPERLY ORGANIZED BINARY COORDINATES OF THE 199250 POINTS] The above file can be imported correctly into ParaView, and at a first glance I can apply the following programmagle filter

Paraview “possible mismatch of datasize with declaration” error

北城以北 提交于 2019-12-21 20:48:17
问题 Paraview (v4.1.0 64-bit, OSX 10.9.2) is giving me the following error: Generic Warning: In /Users/kitware/Dashboards/MyTests/NightlyMaster/ParaViewSuperbuild-Release/paraview/src/paraview/VTK/IO/Legacy/vtkDataReader.cxx, line 1388 Error reading ascii data. Possible mismatch of datasize with declaration. I'm not sure why. I've double-checked that fields are all of the expected lengths, and none of the values are NaN, inf, or otherwise extremely large. The issue starts with the output from

Using Python scripting to plot integration of a variable over a line versus time in ParaView

问题 I have some OpenFOAM simulation results (you may use the official can.ex2 model which can be downloaded from here). What I want to do is: open a file, load the original data as decomposed case (which can't be applied to the case above) apply a Calculator filter one a specific variable (e.g. DISP*3.14*coordsX , I used 3.14 because for the love of god I can't find Pi!) apply filter plot over line [x1,y1,z1] to [x2,y2,z2] integrate the output of 2 over the line defined in 3 in each time step

Visualization of 3-dimensional grid from X_Y_Z(seperate datasets) on Paraview without using xdmf

问题 Reading netcdf files with Paraview using xdmf I used to parse netcdf files with an xdmf script in order to create 3DSMesh on paraview. On top of it, I was adding scalar or vector fields. (So 3DSMesh provides physical coordinates). I never though if it is best way to do that actually. It works, so I was OK. Please let me know if there is more convenient way. I am able to create a 3-dimensional grid with the following script. <?xml version="1.0" ?> <!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []> <Xdmf

Are VTK files endian independent when read in visualization softwares such as Paraview?

喜欢而已 提交于 2019-12-13 21:15:39
问题 I am working on a file whose endian is different from my desktop and I need to convert it, but When I visualized the vtk it worked. So are vtkreaders of vtk files endian independent 回答1: ParaView can read VTK files written using either big- or little-endian byte ordering and will try to work out which format has been used when writing a given file. From the VTK File format documentation: Binary Files. Binary files in VTK are portable across different computer systems as long as you observe

Paraview Python — Reverse operation to servermanager.Fetch()?

老子叫甜甜 提交于 2019-12-13 04:42:38
问题 I am using Paraview with the Python Shell and I want to modify some coordinates. The considered data is opened using a reader, the new coordinates are saved just as txt. I obtain the grid from the reader by using the Fetch()-routine and then modify it -- but my question is: can I somehow "return" the now changed grid to the reader-object and then Show() it? Here is the code used so far: from paraview import simple from paraview.vtk import * import numpy as np reader=simple.LSDynaReader

How to use numpy in the Programmable Filter in ParaView

China☆狼群 提交于 2019-12-12 04:38:18
问题 Assume, I have a ProgrammableFilter in paraview, which gets two inputs: mesh1 with data and mesh2 without. Furthermore, I know the permutation of the points from mesh1 to mesh2. Inside the filter, I can access the point values through data0=inputs[0].GetPointData().GetArray('data')` and obtain a part of the array using subData=data0[0:6] for example. But how could I add this subData to the output without a python loop? To experiment with the code, I created a (not so small) working example: #
