[Paraview] problems starting paraview

Hi! Now I've successfully compiled ParaView 3.8.0, but executing ./paraview, I see that ParaView tries to start up, but exits with a segmentation fault. It seems to me, that some library it is linked to is missing, but how can I find out which one it is? Thanks a lot, Natalie

[Paraview] The best way to extract a disc on a surface ?

Good Morning, I am trying to extract a disc on a surface, that would represent the sensitive surface of a pressure sensor. I tried to use the "Extract Cells by Region" filter, but the sensitive surface could be, in some cases, smaller than the size of a cell. And in these cases, this filter don't

[Paraview] Programmable Source

I am unsure how best to do what I want to do which I shall now describe. I have a Python program that reads in data in a format not supported by ParaView (it actually reads from more than one file which contain different sorts of data). It reformats the data and then writes it out in VTK Legac

[Paraview] zooming in when using perspective projection via vtkCamera.Zoom

Hi, I would like to be able to zoom during an animation using perspective projection. I am doing everything via a Python script. For parallel projection, the transformation is simple and one zooms just by changing a constant factor, i.e., setting the CameraParallelScale variable, and the camera do

Re: [Paraview] zooming in when using perspective projection via vtkCamera.Zoom

I just saw what I wrote...in second and fourth paragraph, I mean *perspective*, not parallel projection... Milos On Fri, Sep 24, 2010 at 11:47 AM, Milos Ilak wrote: > Hi, > > I would like to be able to zoom during an animation using perspective > projection. I am doing everything via a Python s

Re: [Paraview] Programmable Source

Hello David, I am in the same situation. Here is what I have done : 1. Create the reader in python, that works with pvpython, and returns (in my case) a vtkMultiBlockDataSet 2. Then create a "MyReader.xml" file. That calls a vtkPythonProgrammableFilter, in which I import my reader and

[Paraview] Writing multiple implicit functions in one file

Hi, To display ONE implicit function F(x,y,z)=0, I use vtksamplefunction, as shown below. The output of vtkSampleFunction in ImageData format is written to a file using vtkXMLImageDataWritter. How do I write MANY implicit functions in one single file? Put them into cells of unstructured grids?

Re: [Paraview] The best way to extract a disc on a surface ?

While eating, I have thought of a feature that could be interesting : A filter that would generate a certain number of points randomly placed on the intersection of a surface, specified by the user, and a box or a sphere. Do you have any suggestions in order to do this easily, using the existing f

Re: [Paraview] Selecting wall boundary

Hi, If your mesh is structured, you can use the Extract Subset filter. 2010/9/24 Mubashir Ali > Hi, > > I am new to paraview and i want to know how to extract wall boundary cells > in paraview. I am simulating a 3D airfoil which specified as as wall > boundary. > > I am using code saturne which

Re: [Paraview] Multiple implicit functions

Try using the vtkAppendFilter to append all ths functions into a single unstructured grid, and then write that output. BTW, since this is a VTK question, it's best asked on the VTK users list and not ParaView user's list. Utkarsh On Thu, Sep 23, 2010 at 7:28 PM, ChiaWeng Boon wrote: > Hi, > > To

[Paraview] vtkCurvature

Hi everybody, I would like to implement a filter to ParaView which calculates the radius of curvature of streamlines. I've browsed a little and found that there is already a curvature filter, which calculates the Gaussian curvature and the mean curvature using vtkCurvatures. This is nearly w

[Paraview] contour programmable filter

Hi everybody, I begin with Paraview and I would like to have a variable input (like the maximum temperature at each time step) for the isosurface into the contour filter. In this way, I created a programmable filter to get the maximum temperature : pdi = self.GetPolyDataInput() pdo = self.G

Re: [Paraview] contour programmable filter

Using the maximum value of any scalar field as the threshold for an isosurface will always give a null object. In fact, the smallest isosurface you could ever construct is a single triangle, intersecting 3 edges connecting one vertex greater than your threshold, and three other vertices below y
