扫描二维或三维区域的交叉部分，通过三维曲线，得到交叉部分的曲面区域-Sweeps out a 2D cross section (a circle, square, whatever, doesn t even have to be a closed path) through a 3D curve, and returns the generated surface as [X,Y,Z] for use with SURF.

绘制n次Bezier曲线时，应可以输入控制点个数及控制点x,y坐标，输入数据可以放到文本文件中，以便调试。对于三次Bezier曲线，用多个曲线段拼接而成，并且要求曲线一阶导数连续。绘制Bezier曲面时，应可以输入控制多面体的顶点坐标与曲线的间距。-Bezier curve drawing n times, should be able to enter the number of control points and control points x, y coordinates, the i
