Hi Thomas,
Here is code :
node= reader->GetOutput();
node->SetProperty("volumerendering", mitk::BoolProperty::New(true));
mitk::TransferFunction::Pointer tf = mitk::TransferFunction::New();
mitk::Image::Pointer image = dynamic_cast<mitk::Image*>(node->GetData());
mitk::TransferFunctionInitializer::Pointer tfInit =
mitk::TransferFunctionInitializer::New(tf);
tfInit->SetTransferFunctionMode(3);
mitk::GPUVolumeMapper3D::Pointer GPUMapper = mitk::GPUVolumeMapper3D::New();
node->SetMapper(3,GPUMapper);
FourView->GetRenderWindow4()->GetRenderer()->SetMapperID(3);
node->SetProperty("TransferFunction",mitk::TransferFunctionProperty::New (
tf.GetPointer() ) );
node->SetProperty("volumerendering.usegpu",mitk::BoolProperty::New(true),FourView->GetRenderWindow4()->GetRenderer());
node->SetName("InputNode");
m_storage->Add(node);
geometry= m_storage->ComputeBoundingGeometry3D(m_storage->GetAll());
mitk::RenderingManager::GetInstance()->InitializeViews(geometry);
mitk::RenderingManager::GetInstance()->RequestUpdateAll();
I have attached screenshots what I got on running this, what I want it to
be.
Hope you get what is my problem.
Well when I am not using GPU its appearing at focus.
Thanks and Regards
Tab
