Dear Sebastian,
I'm sorry that your email has remained unanswered over the holiday season. Below is a code snippet with the PointSetToCurveGeometryFilter as it usually would be used. Particularly, you may try to explicitly create an instance of Geometry2DDataVtkMapper3D and set it as mapper for the new MPR node. The filter merely encapsulates the MPR functionality, which you also may use more directly, as described in a previous users-list posting: http://www.mail-archive.com/[email protected]/msg00810.html Currently, there is unfortunately no open-source example in MITK which explains how to used curved MPRs, but we plan to integrate curved MPRs in a future release of the 3M3 application, hopefully later this year. Please let us know if you run into further issues. Regards, Mathias // Create and initialize filter instance m_PointSetToCurvedGeometryFilter = mitk::PointSetToCurvedGeometryFilter::New(); m_PointSetToCurvedGeometryFilter->SetInput ( currentPointSet ); m_PointSetToCurvedGeometryFilter->SetImageToBeMapped ( currentImage ); m_PointSetToCurvedGeometryFilter->SetProjectionMode ( mitk::PointSetToCurvedGeometryFilter::YZPlane ); m_PointSetToCurvedGeometryFilter->Update(); mitk::GeometryData::Pointer geometryData = m_PointSetToCurvedGeometryFilter->GetOutput(); this->SetCurrentCurvedGeometryData ( geometryData.GetPointer() ); /* ... */ // Create a node for the curved geometry mitk::DataTreeNode::Pointer node = mitk::DataTreeNode::New(); node->SetData ( geometryData ); mitk::PointSetToCurvedGeometryFilter::SetDefaultCurvedGeometryProperties ( node.GetPointer() ); node->SetProperty ( "name", mitk::StringProperty::New ( "Deformable Plane" ) ); node->SetColor ( 0.0f, 1.0f, 0.0f ); node->SetVisibility ( true ); node->SetVisibility( true, m_MultiWidget->GetRenderWindow4()->GetRenderer() ); node->Modified(); node->GetData()->Modified(); mitk::Geometry2DDataVtkMapper3D::Pointer mapper = mitk::Geometry2DDataVtkMapper3D::New(); mapper->SetDataIteratorForTexture ( this->GetDataTreeIterator() ); node->SetMapper ( 2, mapper ); this->GetDataStorage()->Add ( node, currentImageNode ); > -----Original Message----- > From: sebastian ordas [mailto:[email protected]] > Sent: Wednesday, December 16, 2009 12:17 AM > To: [email protected] > Subject: [mitk-users] curved MPR > > Hello List, > > I wanted to try the curved MPR component in MITK.
