Regaring union of two polygons

[Dilip Baluguri]

Hello everyone,
      Can anyone help me to find union of two polygons (polygons can be
convex or concave). Number of sides are not fixed, it can range from 5 to
50 sides. I do have all the vertices. Can someone help me out with useful
links or Java code. Thanks in advance.

http://java.sun.com/j2se/1.5.0/docs/api/java/awt/geom/GeneralPath.html#append(java.awt.Shape,
boolean)

Note that java.awt.Polygon is a Shape, and note further that the union of
two polygons does not need to be a polygon itself.

Hth,
