Comparison_result Kernel::CompareYAtX_2::operator() | ( | const Kernel::Point_2 & | p, |
const Kernel::Line_2 & | h | ||
) |
compares the \( y\)-coordinates of p
and the vertical projection of p
on h
.
See Figure fig-compare2 (e).
h
is not vertical. Comparison_result Kernel::CompareYAtX_2::operator() | ( | const Kernel::Point_2 & | p, |
const Kernel::Line_2 & | h1, | ||
const Kernel::Line_2 & | h2 | ||
) |
This function compares the y
-coordinates of the vertical projection of p
on h1
and on h2
.
See Figure fig-compare2 (e).
h1
and h2
are not vertical. Comparison_result Kernel::CompareYAtX_2::operator() | ( | const Kernel::Line_2 & | l1, |
const Kernel::Line_2 & | l2, | ||
const Kernel::Line_2 & | h | ||
) |
Let p
be the intersection of lines l1
and l2
.
This function compares the \( y\)-coordinates of p
and the vertical projection of p
on h
. See (Figure fig-compare2 (f)).
l1
, l2
intersect and h
is not vertical. Comparison_result Kernel::CompareYAtX_2::operator() | ( | const Kernel::Line_2 & | l1, |
const Kernel::Line_2 & | l2, | ||
const Kernel::Line_2 & | h1, | ||
const Kernel::Line_2 & | h2 | ||
) |
Let p
be the intersection of lines l1
and l2
.
This function compares the y
-coordinates of the vertical projection of p
on h1
and on h2
. See (Figure fig-compare2 (g)).
l1
and l2
intersect; h1
and h2
are not vertical. Comparison_result Kernel::CompareYAtX_2::operator() | ( | const Kernel::Point_2 & | p, |
const Kernel::Segment_2 & | s | ||
) |
compares the y
-coordinates of p
and the vertical projection of p
on s
.
If s
is vertical, then return CGAL::EQUAL when p
lies on s
, CGAL::SMALLER when p
lies under s, and CGAL::LARGER otherwise.
p
is within the x range of s
. Comparison_result Kernel::CompareYAtX_2::operator() | ( | const Kernel::Point_2 & | p, |
const Kernel::Segment_2 & | s1, | ||
const Kernel::Segment_2 & | s2 | ||
) |
This function compares the \( y\)-coordinates of the vertical projection of p
on s1
and on s2
.
If s1
or s2
is vertical, then return CGAL::EQUAL if they intersect, otherwise return CGAL::SMALLER if s1
lies below s2
, and return CGAL::LARGER otherwise.
p
is within the x range of s1
and s2
.
