Polygon is a python package that handles polygonal shapes in 2D. It contains Python bindings for gpc, the excellent General Polygon Clipping Library by Alan Murta and some extensions written in C and pure Python. With Polygon you may handle complex polygonal shapes in Python in a very intuitive way. Polygons are simple Python objects, clipping operations are bound to standard operators like +, -, |, & and ^. TriStrips can be constructed from Polygons with a single statement. Functions to compute the area, center point, convex hull, point containment and much more are included. This package was already used to process shapes with more than one million points!
Polygon3 works with Python 3.x, Polygon2 with Python 2.x.
