A New Method Deciding Whether a Point is in a Polygon
Abstract:A new method is presented in this paper to decide whether a point is in a polygon. The method combines vector and ray-crossing. And the method quite solves the abnormity which ray-crossing takes on. Experimental results show that the method is robust and efficient in computation.
