WebFeb 9, 2024 · Provide a front end to Angus Johnson's polygon clipping and offsetting algorithms. Two functions are provided: * polyclip (x1,y1,x2,y2,method) finds the difference/intersection/xor/union (depending on "method") between two polygons. * polyout (x1,y1,delta,join,joininfo) outsets a polygon by distance delta, using the given corner join … WebThe Clipper library performs line & polygon clipping – intersection, union, difference & exclusive-or, and line & polygon offsetting. The library is based on Vatti's clipping algorithm. The download package contains the library's full source code (written in Delphi, C++ and C#), numerous demos, a help file and links to third party Python ... WebThe Clipper Library is based on but significantly extends Bala Vatti's polygon clipping algorithm as described in "A generic solution to polygon clipping", Communications of the ACM, Vol 35, Issue 7 (July 1992) pp 56-63.

WebAlgorithm 3.3.5.1. The Vatti polygon-clipping algorithm. the appropriate action based on the vertices that are encountered, we shall see that it therefore basically reduces to a careful analysis of the following three cases: (1) The vertex is a local minimum. (2) The vertex is a left or right intermediate vertex. (3) The vertex is a local maximum. WebClipping 2D polygons is one of the basic routines in computer graphics. In rendering complex 3D images it has to be done several thousand times. Efficient algorithms are …

WebUnlike the Sutherland-Hodgman and Weiler-Atherton polygon clipping algorithms, the Vatti algorithm does not restrict the types of polygons that can be used as subjects or clips. Even complex (self-intersecting) polygons, and polygons with holes can be processed.
