= Point in polygon
{wiki=Point_in_polygon}
The "point in polygon" problem is a common computational geometry problem. It involves determining whether a given point lies inside, outside, or on the boundary of a polygon. This problem has applications in various fields such as computer graphics, geographic information systems (GIS), and collision detection in gaming and simulations. \#\#\# Key Concepts: 1. **Polygon Representation**: A polygon can be represented as a sequence of vertices in a two-dimensional space, typically defined in either clockwise or counterclockwise order.
