Dear Alfred & Taylor,
Thanks for your replies.
I am a beginner to MITK so am still learning various concepts. I tried few
patchy solutions in last few days & one of the solution somehow just
worked.
I used Pointset contours. All the projections in orthogonal planes were
coming properly (currently I am only working with Orthogonal planes)
Following is the code.
mitk::PointSet::Pointer m_pointer_line = mitk::PointSet::New();
mitk::PointSet::PointType start,end;
start[0] = 0.0;
start[1] = 0.0;
start[2] = 0.0;
end[0] = 50;
end[1] = 0;
end[2] = 0;
m_pointer_line->InsertPoint(0,start);
m_pointer_line->InsertPoint(1,end);
mitk::DataNode::Pointer lineNode = mitk::DataNode::New();
lineNode->SetData(m_pointer_line);
lineNode->SetName("Pointer");
lineNode->SetBoolProperty("show points", false);
lineNode->SetBoolProperty("show contour", true);
lineNode->SetBoolProperty("updateDataOnRender", false);
lineNode->SetFloatProperty("contoursize", 1.0);
lineNode->SetIntProperty("line width", 3);
lineNode->SetProperty("contourcolor",
mitk::ColorProperty::New(1.0,0.0,0.0));
m_standalone_datastorage->Add(lineNode);
// m_visualizer is
mitk::NavigationDataObjectVisualizationFilter::Pointer
// m_pointer_pos_relative_img is navigation data
m_visualizer->SetInput(0, m_pointer_pos_relative_img);
m_visualizer->SetRepresentationObject(0, m_pointer_line);
Please let me know if this acceptable way to do it.
Best Regards,
Arpit
