Hi Hongzhi,
the size/geometry of the slice is fine (you can check this by Reinit on the
slice in the Data Manager. However, the standard PlaneGeometry mappers do not
work as you may expect. They use the reference geometry bounds or the world
bounds to cut the planes in shape. You could try to write your own
PlaneGeometry mapper(s) for your PlaneGeometry node or try a different approach
which requires less work, e.g., use a rectangular PlanarFigure to highlight the
ROI in your image slice.
Best,
Stefan

Subject: [mitk-users] Showing an arbitrary reslice of 3D image in
QmitkSliceWidget
Hello everyone,
I'm tring to show an arbitrary reslice of 3D image in QmitkSliceWidget and also
3D view in QmitkStdMultiWidget at the same time.
The orientation of the reslice looks fine, but in QmitkSliceWidget and 3D view
QmitkStdMultiWidget the sizes are not right (see the attachments). It should be
a small square(40x40) (see the source code below).
I really need some help on thie issue. I'm using MITK 2015.05.2 and Ubuntu 14.
Thanks!
Hongzhi
The code is as below:
======================
QmitkSliceWidget* m_SliceWidget=new QmitkSliceWidget(parent);
m_SliceWidget->SetDataStorage(dataStorage);
mitk::PlaneGeometry::Pointer planegeometry = mitk::PlaneGeometry::New();
mitk::Point3D origin;
mitk::Vector3D right, bottom, normal;
mitk::FillVector3D(origin, 1.0, 1.0, 1.0);
mitk::FillVector3D(right, 1.0, 0, 0);
mitk::FillVector3D(bottom, 0, 1.0, 1.0);
planegeometry->InitializeStandardPlane(40,40, right.GetVnlVector(),
bottom.GetVnlVector());
planegeometry->SetOrigin(origin);
mitk::SlicedGeometry3D::Pointer slicedGeo3D=mitk::SlicedGeometry3D::New();
slicedGeo3D->InitializeSlicedGeometry(1);
slicedGeo3D->SetPlaneGeometry(planegeometry,0);
slicedGeo3D->SetReferenceGeometry(node_image3D->GetData()->GetTimeGeometry()->GetGeometryForTimeStep(0));
m_SliceWidget->GetSliceNavigationController()->SetInputWorldGeometry3D(slicedGeo3D);
m_SliceWidget->GetSliceNavigationController()->SetViewDirection(mitk::SliceNavigationController::Original);
m_SliceWidget->GetSliceNavigationController()->Update();
GetDataStorage()->Add(m_SliceWidget->GetRenderer()->GetCurrentWorldPlaneGeometryNode());
