You did not read the documentation about the infinite vertex


http://doc.cgal.org/latest/Triangulation_3/index.html#Chapter_3D_Triangulations

The class Triangulation_3 can also deal with triangulations whose dimension d is less than 3. A triangulation of a set of points in ℝd covers the whole space ℝd and consists of cells having d+1 vertices: some of them are infinite, they are obtained by linking the additional infinite vertex to each facet of the convex hull of the points.
