Thanks for your answer. I added the other value to my PYTHONPATH and i am still stuck with that error. What else could it be ? I added it just like you said , separated by a semicolon, then i restarted my system.

You have to add \python27\VTK\bin also to your system PATH, i.e. via the control panel, else Windows can’t find the DLLs. Adding this to sys.path in Python is not sufficient.

PYTHONPATH needs to get *both*, i.e.:
PYTHONPATH=C:\python27\VTK\bin;C:\python27\VTK\lib\site-packages

hi, i tried what you say in here. But i think im doing something wrong or not doing all the steps. I did this in python cmd line:
import sys
sys.path.append(“C:\python27\VTK\bin”)

in order to add the directory to PATH as you said.
then i went to control panel, system, advanced, environment variables and create PYTHONPATH and give the value of C:\python27\VTK\lib\site-packages. When i try to import vtk it says :”File C:\python27\VTK\lib\site-packages\vtk\common.py from vtk Common import * ImportError DLL load file” .

what am i doing wrong here ?

What about Python 2.7 version?

Sidenote, to install this on my Ubuntu-box (the VTK and Mayavi packages) took me about 10 min of waiting and one painless ‘sudo apt-get install’ command.
Mac – compiling the whole day
Windows – stealing someone else’s binary + environment variables etc. – 50 min.

Thanks for making these binaries available bru.
I’m using them for trying out GIS images in 3D. Just need to figure out how to use color and how to change the height values.

Hi there, I have finally got QVTKRenderWindowInteractor working with your VTK build, and it turned out to be very simple (I am just a beginner with Python and Qt). In case someone is interested here is what I did (and thanks!) :

import vtk
from vtk.qt4.QVTKRenderWindowInteractor import QVTKRenderWindowInteractor

# …
# set up PyQt UI, created with Qt Designer,which includes a
# QWidget named page_VTK, as the 3rd entry in stackedWidget
# …
page_VTK = self.ui.page_VTK
page_VTK.setMaximumSize(QtCore.QSize(800, 600))
self.QVTKRenderWidgetCone(page_VTK)
self.ui.stackedWidget.setCurrentIndex(2)

def QVTKRenderWidgetCone(self,page_VTK):
“”"A simple example that uses the QVTKRenderWindowInteractor class (vtk.qt4).”"”

layout = QtGui.QVBoxLayout(page_VTK)
# create the widget
VTKscene = QVTKRenderWindowInteractor(page_VTK)
VTKscene.Initialize()
VTKscene.Start()
renWin = VTKscene.GetRenderWindow()

layout.addWidget(VTKscene)
ren = vtk.vtkRenderer()
renWin.AddRenderer(ren)

cone = vtk.vtkConeSource()
cone.SetResolution(18)
coneMapper = vtk.vtkPolyDataMapper()
coneMapper.SetInput(cone.GetOutput())
coneActor1 = vtk.vtkActor()
coneActor1.SetMapper(coneMapper)
coneActor2 = vtk.vtkActor()
coneActor2.SetMapper(coneMapper)
ren.AddActor(coneActor1)
ren.AddActor(coneActor2)

coneActor1.SetPosition(2, 0, 1)
coneActor2.SetPosition(0, 2, 0)
# show the widget
VTKscene.show()

My knowledge of PyQt and VTK is still pretty rudimentary. If you have the patience, here is my post to the PyQt list describing my failed attempt to do the job programmatically:

There could well be a way use a placeholder in Designer then build the QVTKWidget programmatically, but I haven’t been able to find it yet. I’ve seen some very suggestive hints, but for me they don’t quite work as advertised. Supposedly a QWidget can be promoted to a QVTKWidget in Designer, but in my case all the steps seem to be OK but the promotion doesn’t occur. What I find puzzling is that the VTK example:
VTK\Examples\GUI\Qt\SimpleView\uiSimpleView4.ui contains such a promoted QVTKWidget, which is displayed in DEsigner as such. I guess it’s in the ui code, but the associated support is missing from my installation.
