CGAL 4.12.1 - 2D Arrangements

Computes the overlay of two arrangements with history arr1 and arr2, and sets the output arrangement with history res to represent the overlaid arrangement.

Computes the (simple) 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).

The function also constructs a consolidated set of curves that induce res. It employs the default overlay-traits, which practically does nothing.

Precondition
res does not refer to either arr1 or arr2 (that is, "self overlay" is not supported).

## Classes

class  CGAL::Arr_default_overlay_traits< Arrangement >
An instance of Arr_default_overlay_traits should be used for overlaying two arrangements of type Arrangement that store no auxiliary data with their Dcel records, where the resulting overlaid arrangement stores no auxiliary Dcel data as well. More...

class  CGAL::Arr_face_overlay_traits< Arr_A, Arr_B, Arr_R, OvlFaceData >
An instance of Arr_face_overlay_traits should be used for overlaying two arrangements of types Arr_A and Arr_B, which are instantiated using the same geometric traits-class and with the Dcel classes Dcel_A and Dcel_B respectively, in order to store their overlay in an arrangement of type Arr_R, which is instantiated using a third Dcel class Dcel_R.
