Hi Mathias,
thank you for your quick help. I tried the following:
// setup TPS transform
mitk::ThinPlateSplineCurvedGeometry::Pointer pTPS =
mitk::ThinPlateSplineCurvedGeometry::New();
pTPS->SetTargetLandmarks(m_pSelectedPntSet->GetPointSet()->GetPoints());
// create mitk::GeometryData
mitk::GeometryData::Pointer pGeometryData = mitk::GeometryData::New();
pGeometryData->SetGeometry(pTPS);
// replace data tree node
mitk::DataTreeHelper::RemoveNode("CurvedMPR");
mitk::DataTreeNode::Pointer pNode = mitk::DataTreeNode::New();
pNode->SetData(pGeometryData);
mitk::DataTreeHelper::AddNode("CurvedMPR",pNode);
The node appears in the data tree but does not have any effect. Is there a
special way I have to insert the node?
Does it matter whether it is in front of or behind the image volume? Added to
the root or to the image node?
Thank you,
Michael.

Subject: RE: Curved MPR
Hi Michael,
MITK does support curved MPRs. They integrate nicely into the geometry
framework of MITK: The class mitk::ThinPlateSplineCurvedGeometry derives from
mitk::Geometry2D and thus represents a curved 2D plane in space. The spline
geometry is defined by landmarks in 3D space.
Curved MPRs can be visualized using the mappers mitk::Geometry2DDataMapper2D
(for flat mappings in 2D views) and mitk::Geometry2DDataVtkMapper3D (for curved
mappings in 3D views). To do so, an mitk::GeometryData object containing a
properly initialized instance of mitk::ThinPlateSplineCurvedGeometry needs to
be created and inserted into the DataStorage. The mapper then reslices all
visible data with this curved 2D plane (in the same way as the "normal" 2D
geometries for transversal, sagittal and coronal directions are displayed).
Regards,
Mathias

Subject: [mitk-users] Curved MPR
Hi,
Does MITK support curved MPRs?
If not, what would be the best way to implement that? Would I have to write a
new Mapper2D?
How could I use of such a new 2D mapper for volume data?
Thanks,
Michael.
