Hi Thomas, I checked my code again and found where the issue comes from. The code is correct but their sequence needs to be changed.
In the step of connecting DataStorage to render, MITK will update the m_CurrentWorldGeometry2D with default value, so the step of set up a 2D geometry in renderer must appear behind the DataStorage connection. Thanks anyway Li ________________________________________ 发件人: Liu, Li [[email protected]] 发送时间: 2012年4月30日 16:38 收件人: Kilgus, Thomas; [email protected] 主题: [mitk-users] 答复: spatial placement of slice in mitk::ImageVtkMapper2D Hi Thomas, I only want to rendering 2D image now, so I think it is good for me. Arbitrary reslicing is absolutely useful for me in future design and I am looking forward to seeing it. A simple question about the rendering, I can 2D view of volume data, but it is not what I set up in Geometry of BaseRenderer. Now the view is always the first slice in Transversal direction. I have read several discussions and introduction, but no clue to continue. Can you give me some advices? Here is what I did in my code: 1. New Qmitk render window renderWindow = new QmitkRenderWindow(); 2. Load in 3D volume data to MITK Data Node (Volume data size is 309*547*478) nodeReader = mitk::DataNodeFactory::New(); nodeReader->SetFileName(infilename); nodeReader->Update(); node = mitk::DataNode::New(); node = nodeReader->GetOutput(); 3. New imageVtkMapper vtkMapper = mitk::ImageVtkMapper2D::New(); vtkMapper->SetDefaultProperties(node,renderWindow->GetRenderer()); 4. Initialize a plane and set up a 2D geometry (I am sure 200 is inside of volume data) planeGeo = mitk:: PlaneGeometry::New(); planeGeo->InitializeStandardPlane(node->GetData()->GetGeometry(),mitk::PlaneGeometry::PlaneOrientation::Transversal,200); 5. Set up renderer geometry (It will use mitk::BaseRenderer::SetCurrentWorldGeometry2D) renderWindow->GetRenderer()->SetWorldGeometry(planeGeo); 6. Set up data note mapper node->SetMapper(mitk::BaseRenderer::Standard2D,vtkMapper); 7. Connect Data Storage to renderer storage=mitk::StandaloneDataStorage::New(); storage->Add(node); renderWindow->GetRenderer()->SetDataStorage(storage); 8. Update renderer mitk::RenderingManager::GetInstance()->RequestUpdateAll(); 9. show rendering window renderWindow->show(); Thanks Li ________________________________________ 发件人: Kilgus, Thomas [[email protected]] 发送时间: 2012年4月27日 3:43 收件人: Liu, Li; [email protected] 主题: AW: [mitk-users] spatial placement of slice in mitk::ImageVtkMapper2D Hi Li, if you set up the geometry of the 2D slice of the corresponding renderer correctly (see mitk::BaseRenderer::SetCurrentWorldGeometry2D(Geometry2D* geometry2d )), the current implementation of the ImageVtkMapper2D will compute the extent for your arbitrary slice internally. This happens in the method CalculateClippedPlaneBounds. Note: I would rather not recommend to use this mapper, which is meant for rendering, as a filter. We are currently working on a filter class performing arbitrary reslicing. It is almost ready for being merged into the master.

But I got a question here after quickly browsing the ImageVtkMapper2D::GenerateDataForRenderer, it seems this function requires user to set up the 2D geometry of slice, like extent, origin, plane vector etc. In contrast, the vtkImageReslice only needs user inputs the vector of plane and a point that the plane passes through in its example code. If I don't compute slice extent, I think the ImageVtkMapper2D can not work like I expect. If slice vector is aligned to axial, coronal or sagittal direction, it is easy to know the extent of slice, but for any others, it needs additional coding to get extent. My question is if MITK can get 2D slice that is bounded by 3D volume geometry when only imputing plane vector and a point that plane passes through? Thanks.
