在传统解析几何中，平面区域未被作为点的轨迹来看待，因此没有研究平面区域的方程问题。
The convex polygon is constructed by vector product in order to solve the straightness error.为求解直线度误差，采用矢量积构造凸多边形。
An attempt has been made to compare different algorithms which are based on the methods of 0.618, standard rotation and convex polygon.对0.618法、基准旋转法和凸多边形法等不同算法的比较进行了尝试。
