Polygon Fill Areaa polygon (polygon) is mathematically defined as a planar shape described by three or more coordinate positions called vertices, which are connected sequentially by edges (edge or side) called a multilateral nature . further ,

Polygon Table       objects in a scene are generally described by a set of polygon patches. In fact, graphics packages often provide functions that describe surface shapes in polygonal meshes. A description of each objectincludes geometry

One, determine if the point is in the polygon (theory) To determine whether point P is a very basic but very important algorithm in the computation geometry in the polygon. With point P as the endpoint, to the left as the Ray L, because the polygon

Method for Determining Convex Polygon In the calculation of geometric and geographic information systems, it is very important to determine the convex and convex aspects of polygon. So what are concave polygon and convex polygon? First, we can

Split Concave polygonOnce the concave polygon is identified, we can cut it into a set of convex polygons. This can be done using the edge vector and the edge cross product. We can use the relationship of vertex and edge extension lines to determine

The fifth chapter of this book is very good B. It describes a series of Theorem related to the inner graph of polygon and its proof. Interestingly, it is also a research on the interior drawing of polygon. When the research objects are different,

Judge whether a point is in the irregular image of the internal algorithm, as the irregular image composed of points, to determine whether a point in the irregular rectangle inside, first onAlgorithm is implemented as follows, the algorithm is

There is an n-sided shape, the vertex is P1,P2,..., pn; Given a known point P, determine whether p is inside or outside the polygon.Preliminary knowledge: The definition of intersection of two segments, if the ends of one segment are at both ends of
