CGAL 5.1.2 - 2D Regularized Boolean Set-Operations
|
A model of this concept represents a simple general-polygon. The geometric mapping of the edges of the polygon must be \( x\)-monotone curves. The concept requires the ability to access these curves. The general polygon represented must be simple. That is, the only points of the plane belonging to two curves are the geometric mapping of the polygon vertices. In addition, the vertices of the represented polygon must be ordered consistently, and the curved must be directed accordingly. Only counterclockwise oriented polygons are valid operands of Boolean set-operations. General polygon that represent holes must be clockwise oriented.
