If you do as what I suggested, you can store the computed dual points of cells, so they will not be computed again and again.

Sorry for the confusion, that was a typo. I am writing a relatively large program, so that was only a snapshot I made for demonstration purpose. I had a few mistakes there, the most serious one is I left out a      !             before segment.is_degenate() which made the logic incorrect. It worked after that fix. I am trying to  

implement what you suggested. By working counter-clockwise, I can get all segments of the power cell in the right order, because my eventual goal is to get the power cell polygon. Hopefully it will go well. Thanks for your suggestion.

I have not test your code, but I found some mistakes. Can this be compiled?
segments is std::vector<Point_2>. Segment can not be inserted into it.
RT::incident_edges and so on are not static functions, I don't think they can be used like this.

Linking the dual points of two neighbor incident cells of a vertex is pretty much the same as getting the dual of the corresponding incident edge of that vertex.  Do you have any idea why my approach didn't work ?

Why not just link the dual points of the incident cells?

I test the code, and for each vertex, it only collected two segments of the
power cell. Therefore, it is clearly incorrect. Anyone has any suggestion
how to achieve my goal?
