Operations | |
A model of this concept must provide: | |
| Comparison_result | operator() (const Kernel::Point_2 &p, const Kernel::Line_2 &h) |
compares the \( x\)-coordinates of p and the horizontal projection of p on h. | |
| Comparison_result | operator() (const Kernel::Point_2 &p, const Kernel::Line_2 &h1, const Kernel::Line_2 &h2) |
compares the \( x\)-coordinates of the horizontal projection of p on h1 and on h2. | |
| Comparison_result | 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. | |
| Comparison_result | 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. | |
| Comparison_result Kernel::CompareXAtY_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 \( x\)-coordinates of p and the horizontal projection of p on h.
See Figure fig-compare_x_at_y_2 (c).
| Comparison_result Kernel::CompareXAtY_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 \( x\)-coordinates of the horizontal projection of p on h1 and on h2.
See Figure fig-compare_x_at_y_2 (d)).
| Comparison_result Kernel::CompareXAtY_2::operator() | ( | const Kernel::Point_2 & | p, |
| const Kernel::Line_2 & | h | ||
| ) |
compares the \( x\)-coordinates of p and the horizontal projection of p on h.
See Figure fig-compare_x_at_y_2 (a).
| Comparison_result Kernel::CompareXAtY_2::operator() | ( | const Kernel::Point_2 & | p, |
| const Kernel::Line_2 & | h1, | ||
| const Kernel::Line_2 & | h2 | ||
| ) |
compares the \( x\)-coordinates of the horizontal projection of p on h1 and on h2.
See Figure fig-compare_x_at_y_2 (b).
