I'm back to ask questions.

<http://cgal-discuss.949826.n4.nabble.com/file/n4655874/09%E7%9A%84%E5%B1%8F%E5%B9%95%E6%88%AA%E5%9B%BE.png>
 

As shown above, some vertex are covered by circular arcs respectively. This
structure is implemented in CGAL by Arrangement with
Arr_circle_segment_traits_2 trait. Now two things should be done:
  1. compute the areas of faces surrounding each vertex;
  2. get the nearest and farthest point to the vertes on outer arcs.

Thx for your reply ahead.
