Hi list, my goal is to set up an arbitrary plane in space with an image on it (image in space). This is what can be done in VTK with the vtkImageActor.
As you can see in the attached discussion, I tried to use mitk::Geometry2DData, mitk::Geometry2DDataVtkMapper3D and mitk::ImageMapper2D to get something like the vtkImageActor in MITK. That still does not work for me. It seems like the ImageMapper2D extracts an empty image. But that is another story. So I was wondering if it is possible to integrate an vktImageActor into the DataTree? Can you please tell me how to do that? I appreciate every help!
