vector polygon

基本解释

The algorithm of transferring vector polygon to raster data is one of the basic algorithms of GIS.
矢量多边形的栅格化算法是地理信息系统的基础算法之一。
At the same time the author points out that the polygon vertexes can be sorted clockwise or anticlockwise by judging the sign of the vector polygon area.
同时指出可以通过判断矢量多边形面积的正负值将多边形的顶点按照顺时针或逆时针方向排序。
The differential method for the mechanic movement analysis is proposed in this paper. With the method, only the displacement vector polygon of a mechanism is needed to be established.
导数法机构运动分析只需建立运动机构的位移矢量多边形，然后利用位移、速度、加速度之间的函数关系来完成速度、加速度分析。
