Hi


Sure, take a look into vtkXMLPolyDataWriter

Hi Mathieu,

Thank you for the quick reply! I have some .vtp files and tried the way you told me, and got the result what I want. However, I don't know how to convert my .vtk files to .vtp files. Could you please give me more information about this? And, can I generate .vtp files from a simulation code by using some vtkwriter object?

Sincerely
-Zhang

Hi

It is quite simple.

First convert your file to modern file type, eg .vtu , .vtp or .vti

Then manually create a .pvtu/p/i with the correct syntax.


Take a look at the attached file file.pvtp

Hello,

I'm using ParaView for parallel visualization. My dataset is polydata, it is not "parallel aware". However, using the D3 filter, as the ParaView User's Guide says, is too expensive, which slow down the whole process significantly. As my data is  generated in parallel, I want to assign these data files to  multiple pvservers. For example, I have a dataset contains four files: file0.vtk, file1.vtk, file2.vtk and file3.vtk. Note that they are not temporal file series, but each represent a different area of the simulation domain. And, I start four pvservers by mpirun -np 4 ./pvserver. I can connect to the pvserver using paraview GUI on my PC, but I don't how to distribute the four files to each pvserver. I tried to select the four files using the Ctrl key and hit Apply, but it seems that they are all assigned to the process 0. Is there any way I can distribute the data files to each pvserver using the paraview GUI?

Thanks a lot!
-Zhang
