Convexhullproblem
- 点集Q的凸包(convex hull)是指一个最小凸多边形,满足Q中的点或者在多边形边上或者在其内-The convex hull of point set Q (convex hull) is a minimum convex polygon, to meet the Q of the point or the edge of or within this polygon
polyJudge
- 判断是否是凸多边形,包含可视化界面,用户输入。-Determine whether a convex polygon that contains visual interface, user input.
CH
- 令S是平面上的一个点集,封闭S中所有顶点的最小凸多边形,称为S的凸包,表示为CH(S)。如下图中由红色线段表示的多边形就是点集Q={p0,p1,...p12}的凸包。-ConvHull problem
