Package toxi.geom

Class ConvexPolygonClipper

java.lang.Object

toxi.geom.ConvexPolygonClipper

All Implemented Interfaces:

PolygonClipper2D

public class ConvexPolygonClipper
extends Object
implements PolygonClipper2D

A more generic version of the Sutherland-Hodgeman algorithm to limit 2D polygons to convex clipping regions. Uses the clipping region's centroid and Line2D.classifyPoint(ReadonlyVec2D) to identify if an edge needs to be clipped or not.
