VTK to Blender Python Script

Coding Python Support
1

Refering to the post at http://www.blender.org/forum/viewtopic.php?t=5868
I believe that I have posted my questions in the wrong section of the Forum.
Problem is as followed…

Refering to the Python Script to create an link between Blender and the VTK file set using Python, I have encountered some problems.

The purpose of using Blender with the VTK file set is to be able to use designed work in Blender to be able to use them in Kitware Paraview also vis-versa.

From this site as I followed the instructions
http://www.ualberta.ca/CNS/RESEARCH/Vis/VTKBlender/
I have encountered a problem when attempting to Run the Python script vtk_to_blender.py

WindowsXP Pro
Blender 245
Paraview 3.3.0
Python 2.5

Because the Python Script in Blender couldn’t find the VTK Library, I Ran the following line:

##############
import sys
sys.path.append(‘D:\ParaViewRelease1659VS8Qt434\Utilities\VTKPythonWrapping\paraview’)
sys.path.append(‘D:\ParaViewRelease1659VS8Qt434\bin\release’)
sys.path.append(‘D:\ParaViewRelease1659VS8Qt434\Utilities\VTKBlender’)
##############

The problem occured on line 164 from the “vtk_to_blender.py” script
Error message as shown in the console:

Traceback (most recent call last):
File “vtk_to_blender.py” line 164, in (module)
File “vtk_to_blender.py” line 23, in main
File “vtk_to_blender.py” line 124, in GetExtrudedline
AttributeError: ‘module’ object has no attribute ‘vtkLineSource’

I have emailled the UofA regarding this and this is what I had in return.

I suspect you need to
find the paraview directory that has the vtk Libraries in it and
add it to your PYTHONPATH with the sys.path.append() call.
I think the particular library with the vtkLineSource is
vtkGraphics.dll on windows.

On my coworkers window machines, the vtk dll’s are found
in C:\Program Files\Paraview\bin, so maybe add the following
line:

sys.path.append(‘D:\ParaViewRelease1659VS8Qt434\bin’)

After recieving this, the path “‘D:\ParaViewRelease1659VS8Qt434\bin\release’” does contain the vtkGraphics.dll and other Libraries.

If the problem could be a missing library file, the following is what contains in that path.

The Following is the content of the “release” directory.

Thank you!

To add, I haven’t tried out this other script from another thread which in theory could work.
