Clipping Random Polygons

This page presents primary boolean operations between two sets of polygons. The subject polygon is blue and clip is red. Both sets have 23 sub polygons each consisting of four points. Which means that subject polygon as well as clip polygon has 92 points, totally 184 points.

The result of boolean operations produced about 800- 2300 points. This huge addition in point count is due to self intersections of source polygons. Because they are generated randomly (in Javascript) without check for self intersections, this means that intersection points are added by Clipper library during execution of boolean operations. The result of boolean operations of Clipper library has never self intersection points (at least according to my tests with thousands of examples).

These examples are screen captures of Main Demo program, which uses Javascript Clipper library.
