Hi Frederico,
if you need to display only one additional resampled plane in the 3D
window, the following trick might help:
// get the 3D window
mitk::BaseRenderer::Pointer renderer =
this->GetRenderWindowPart()->GetQmitkRenderWindow(QString("3d"))->GetRenderer();
// with "plane" being the PlaneGeometry that describes the position of
your slice
// and "image" being the 3D image volume you want to reslice
plane->SetReferenceGeometry(image->GetGeometry());
// part 1 of the trick: tell the renderer to use this as its worldgeometry
renderer->SetWorldGeometry(plane);
// part 2 of the trick: add the DataNode containing the worldgeometry of
the renderer to the DataStorage
mitk::DataNode::Pointer planenode =
renderer->GetCurrentWorldGeometry2DNode();
this->GetDataStorageReference()->GetDataStorage()->Add(planenode);
Maybe there is also another, more elegant solution to the problem. This
may require a (maybe not yet existing) mapper for rendering 2D images in
3D.
Best,
Ivo
