CGAL::overlay
Definition
The function overlay computes the overlay of two input arrangement
objects, and returns the overlaid arrangement. All three arrangements
are instantiated using the same geometric traits class, but may be
represented using different DCEL classes. A given overlay-traits object
is used to properly construct the overlaid DCEL that represents the
resulting arrangement.
#include <CGAL/Arr_overlay.h>
|
template<typename Traits, typename Dcel1, typename Dcel2, typename ResDcel, typename OverlayTraits>
|
|
void
|
|
Computes the overlay of two arrangements arr1 and arr2, and sets
the output arrangement res to represent the overlaid arrangement.
Precondition
res does not refer to either arr1 or arr2
(that is, ``self overlay'' is not supported).
#include <CGAL/Arrangement_with_history_2.h>
|
template<typename Traits, typename Dcel1, typename Dcel2, typename ResDcel, typename OverlayTraits>
|
|
void
|
|
Computes the overlay of two arrangements with history arr1 and
arr2, and sets the output arrangement with history res to
represent the overlaid arrangement. The function also constructs a
consolidated set of curves that induce res.
Precondition
res does not refer to either arr1 or arr2
(that is, ``self overlay'' is not supported).
Requirements
- The overlay-traits object ovl_tr must model the OverlayTraits
concept, which is able to construct records of the ResDcel class on
the basis of the Dcel1 and Dcel2 records that induce them.
