WebThis algorithm is sometimes also known as the crossing number algorithm or the even–odd rule algorithm, and was known as early as 1962. The algorithm is based on a simple observation that if a point moves along a ray from infinity to the probe point and if it crosses the boundary of a polygon, possibly several times, then it alternately goes from … Web6 sep. 2005 · A linear algorithm for determining the translation separability of two simple polygons, Report SOCS-86.1, School Comput.
