Hey Tobi,
Okay, I have found the problem: After setVtkPolyData I modify the
vtkPolyData of the surface without calling CalculateBoundingBox()
afterwards. Now calculating the bounding box and a "Global Reinit" fixes the
problem.
For the code example I gave I could to something like that:
for (mitk::DataStorage::SetOfObjects::ConstIterator it = rs->Begin(); it !=
rs->End(); it++)
{
mitk::Surface* surface =
reinterpret_cast<mitk::Surface*>(it->Value()->GetData());
if (surface)
{
surface->CalculateBoundingBox();
...
}
}
Now I have a small question: Is it possible to adjust the plane widgets
(number of slices and dimensions) without changing the zoom of the 3D view
in the StdMultiWidget? Now after I do a Global Reinit the view is reset to a
point where the whole scene can be looked at. Can I avoid this somehow?
Thanks for directing me in the right direction with the corrupted geometry.
Regards, Benjamin
