The vatti clipping algorithm

WebThe Vatti clipping algorithm[1] is used in computer graphics. It allows clipping of any number of arbitrarily shaped subject polygons by any number of arbitrarily shaped clip polygons. Unlike the Sutherland–Hodgman and Weiler–Atherton polygon clipping algorithms, the Vatti algorithm does not restrict the types of polygons that can be used as … Web##About this repo Vatti polygon clipping algorithm implementation to perform polygon boolean operations union, intersection, difference and XOR. Though this repository can be used for academic purpose. so far work done works for self intersecting polygons and polygons with holes. works for multipolygon in subject or clip TODO
