Polygon line intersection algorithm

WebPolygon triangulation. In computational geometry, polygon triangulation is the partition of a polygonal area ( simple polygon) P into a set of triangles, [1] i.e., finding a set of triangles with pairwise non-intersecting interiors whose union is P . Triangulations may be viewed as special cases of planar straight-line graphs. WebIn computational geometry, a sweep line algorithm or plane sweep algorithm is an algorithmic paradigm that uses a conceptual sweep line or sweep surface to solve various problems in Euclidean space.It is one of the critical techniques in computational geometry. The idea behind algorithms of this type is to imagine that a line (often a vertical line) is …
