of lines and . This function
compares the -coordinates of the vertical projection of p on
h1 and on h2, see (g) in the figure

compare_y_at_x ( Point_2<Kernel> p, Segment_2<Kernel> s)
|
| |
compares the -coordinates of and the vertical projection
of p on s. If s is vertical, then return
EQUAL when p lies on s, SMALLER when p lies
under s, and LARGER otherwise.
| Precondition: | p is within the x range of s. |

compare_y_at_x ( Point_2<Kernel> p, Segment_2<Kernel> s1, Segment_2<Kernel> s2)
|
| |
compares the -coordinates of the vertical projection
of p on s1 and on s2. If s1 or s2
is vertical, then return EQUAL if they intersect, otherwise return
SMALLER if s1 lies below s2, and return LARGER
otherwise.
| Precondition: | p is within the x range of s1 and s2. |
