Web$\begingroup$ If the problem involves test many points on the same polygon. It can be done in O(log n) per query with Kirkpatrick's triangulation refinement method. Which is like triangulating the polygon at different levels. $\endgroup$ – Chao Xu. Jul 21, 2010 at 12:35. Add a comment In computational geometry, the point-in-polygon (PIP) problem asks whether a given point in the plane lies inside, outside, or on the boundary of a polygon. It is a special case of point location problems and finds applications in areas that deal with processing geometrical data, such as computer graphics, … See more One simple way of finding whether the point is inside or outside a simple polygon is to test how many times a ray, starting from the point and going in any fixed direction, intersects the edges of the polygon.

If the winding number is non-zero, the point lies inside the polygon. This algorithm is sometimes also known as the nonzero-rule See more The point in polygon problem may be considered in the general repeated geometric query setting: given a single polygon and a … See more
