The vatti clipping algorithm

WebThe Vatti clipping algorithm 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 subjects or clips. WebJul 30, 2015 · By interpreting your problem as trying to find a (potentially convex) contour of many thin rectangles in the plane, you can use Vatti's clipping algorithm to get the contour. Here is one such way: Do a large union of all the rectangles in the plane; Discard all 'holes' and consider only the outer contours; Do another union on all the outer contours

In three-dimensional graphics, the terminology of clipping can be used to describe many related features. …

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. Web摘要：. In this paper a new computationally efficient and high performance channel estimation algorithm is proposed for the indoor visible light communication (VLC) sparse channels in the presence of a clipping noise. The clipping noise is modelled as a Gaussian mixture and, a first time in the literature, the matching pursuit (MP) and the ...

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. WebA key fact that is used by the Vatti algorithm is that polygons can be represented via a set of left and right bounds which are connected lists of left and right edges, respectively, that …
