Hi,
I'm new to MITK and I would like to use it to display tubes around a
polyline that I have generated using "vtkTubeFilter". The code works
fine when using VTK only but I would like to integrate it into some
application that uses MITK.
I have successfully visualized data from other sources with MITK
already, however, there seems to be a problem with the output of
"vtkTubeFilter". Below you find my code, which works fine for other
data, but not in this particular case. In the 2D-views of the
QmitkStdMultiWidget, I can see the cross-sections of the tubes, but
nothing is visualized in the 3d-view. My original vtkPolyData which
serves as an input to vtkTubeFilter consists only of points and the
connecting polyline.
Any help is deeply appreciated.
Thanks in advance,
Steffen
