Symmetric Difference Functions
2D Regularized Boolean Set-Operations Reference

Each one of these functions computes the symmetric difference between two given polygons p1 and p2, and inserts the resulting polygons with holes into an output container through the output iterator oi. The value type of the OutputIterator is either Polygon_with_holes_2 or General_polygon_with_holes_2.

The signature of the function is

OutputIterator symmetric_difference(const Type1 & p1, const Type2 & p2, OutputIterator oi);

Parameters

The types of the paramters of the symmetric_difference() function are any of the following combinations.

Arg 1 typeArg 2 type

Function Documentation

template<class InputIterator , class OutputIterator >
OutputIterator CGAL::symmetric_difference ( InputIterator  begin,
InputIterator  end,
OutputIterator  oi 
)

computes the symmetric difference of the general polygons (or general polygons with holes) in the given range.

A point is contained in the symmetric difference, if and only if it is contained in an odd number of input polygons. (The value type of the input iterator is used to distinguish between the two.) The result, represented by a set of general polygon with holes, is inserted into an output container through a given output iterator oi. The output iterator is returned. The value type of the OutputIterator is Traits::Polygon_with_holes_2.
