Kernel::Point_2 | fo.operator() ( Kernel::Segment_2 s, int i) | |
returns source or target of s: fo(s,0) returns the source of s, fo(s,1) returns the target of s. The parameter i is taken modulo 2. | ||
Kernel::Point_2 | fo.operator() ( Kernel::Iso_rectangle_2 r, int i) | |
returns the i'th vertex of r in counterclockwise order, starting with the lower left vertex. The parameter i is taken modulo 4. | ||
Kernel::Point_2 | fo.operator() ( Kernel::Triangle_2 t, int i) | |
returns the i'th vertex of t. The parameter i is taken modulo 3. |
