[vtkusers] Rotating an Image ina 3D scene

[Fabian Torres]

Hi.

I`m trying to display some images in a 3D view in VTK. I have calculated
the transformation to display the images in the correct place.


I`m using vtkTransform and vtkImageActor to display the images

vtkSmartPointer<vtkTransform> transform
                =
this->computeTransformation(volumeDataRotations.get_row(i),
volumeDataTranslations.get_row(i), volumeDataCalibration);

actor->SetUserTransform(transform);
actor->SetScale(volumeDataCalibration[6],volumeDataCalibration[7],1);

renderer->AddActor(volumeImageActorStack.at(i));
renwin->AddRenderer(renderer);
renwin->Render();

This displays the image in the correct position, but when I try to get the
position of the actor

actor->GetPosition();

in the scene I get (0,0,0)
