Thank you so much for your suggestions, but I don't have any clue about how to use Planar Figures or the camera to achieve what I want. I tried to find some example code in MITK source about planar figures, but I didn't find any that can help my work. Could you give me some examples or links to me? I really appreciate it!

Hence, I would *not* recommend to write your own mappers, as this is rather complicated and I don't see a huge advantage compared to using planar figures for user guidance which would justify the amount of work. As an alternative, you could also work with the camera of your extra 2D window to focus on the vessel in that window, as it seems like the user is segmenting only in this window anyways. Please also note that we integrated the Vascular Modeling Toolkit into our superbuild (MITK_USE_VMTK), which may be of help to you for what you are trying to achieve.

Then, next step is to to create a group of 2D contours(segmentation) using those reslices by hand or level set to define vessel shape at each cross sections (see attachment) . Finally I use the group of 2D contours to create a polydata surface for the whole vessel. This is what I want to achieve. Do you think specialized mappers are the best option for my need? Or do you have some other suggestions? Thanks a lot!

The question is what you want to achieve? Why are you using the extra slice? Do you want to show the user something on that slice? Then maybe it is okay to live with the current solution but as a workaround display a PlanarFigure on top of your extra slice to emphasize the region of interest in the extra slice?

You mean, for PlaneGeometry I may need to write alternatives for PlaneGeometryDataMapper2D and PlaneGeometryDataVtkMapper3D? If using PlanarFigure, can I show an arbitrary reslice of 3D image in both QmitkSliceWidget and 3D view in QmitkStdMultiWidget? Are there any examples about how to use PlanarFigure to do this?

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.

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!
