polygon geometry

基本解释

In this paper a new geometry compression algorithm for general polygon meshes is introduced.
提出一个通用的一般多边形网格的几何压缩算法。
Applying this method on the result of ST_Envelope, which always returns a polygon for any non-empty geometry, gives us the single point we need.
将这个方法应用到 ST_Envelope（对于任何非空的几何图形，它总是返回一个多边形）的结果上将得到我们需要的那个点。
A method for seal identification is proposed, which based on cupidity algorithm and polygon triangulation cutting algorithm in computational geometry.
将计算几何中平面点集的三角剖分方法-贪心算法引入印鉴识别，研究了一种基于三角网格的印鉴匹配方法。
