CGAL 4.12 - 2D Polygons
2D Polygon Reference

Geert-Jan Giezeman and Wieger Wesselink
This package provides a 2D polygon class and operations on sequences of points, like bounding box, extremal points, signed area, simplicity and convexity test, orientation, and point location. The demo includes operations on polygons, such as computing a convex partition, and the straight skeleton.

Introduced in: CGAL 0.9

Windows Demo: Operations on Polygons
Common Demo Dlls: dlls


The assertion flags for the polygons and polygon operations use POLYGON in their names (e.g., CGAL_POLYGON_NO_ASSERTIONS).
