The function create_exterior_straight_skeleton_2 creates a straight skeleton in the exterior of a 2D polygon with holes.

| returns a new Straight_skeleton_2<K> in the limited exterior of the 2D polygon P given by the point sequence [vertices_begin,vertices_end]. The skeleton in the limited exterior of P is the skeleton in the interior of a polygon Q with P as its hole and a rectangular frame F as outer boundary. The outer boundary F is constructed by enlarging the bounding box of P a distance d. d is a margin sufficiently large to allow an outer offset at dinstance max_offset to be obtained from this exterior skeleton, as computed by the function compute_outer_frame_margin | ||||
