com.seisw.util.geom.Clip

public class Clip
extends java.lang.Object

Clip is a Java version of the General Poly Clipper algorithm developed by Alan Murta (gpc@cs.man.ac.uk). The home page for the original source can be found at http://www.cs.man.ac.uk/aig/staff/alan/software/.

polyClass: Some of the public methods below take a polyClass argument. This java.lang.Class object is assumed to implement the Poly interface and have a no argument constructor. This was done so that the user of the algorithm could create their own classes that implement the Poly interface and still uses this algorithm.

Implementation Note: The converted algorithm does support the difference operation, but a public method has not been provided and it has not been tested. To do so, simply follow what has been done for intersection.
