There is an excellent writeup in … WebJan 13, 2015 · The function intersect ( line1, line2 ) tries to compute the intersection of line1 and line2; it includes a primitive sort of guard against numeric overflow, and returns a point (a tuple (x,y)). The line data structure used ensures that line endpoints are compatible with Pygame's line-drawing routines, e.g.:
WebGiven two circular-arc polygons with m and n edges respectively, our method runs in O (m+n+ (l+k)logl) time, using O (m+n+k) space, where k is the number of intersections, and … 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.
