OpenGL绘制的B样条、贝塞尔曲线和贝塞尔曲面，可以鼠标选取关键点绘制曲线，可以鼠标对关键点进行拖拽，实现平移，旋转操作-OpenGL rendering B-spline, Bezier curves and Bezier surfaces, you can draw the curve of the mouse select the key points, you can drag the mouse right key points to achieve translation, rot

本程序框架采用OpenGL+MFC SDI，其中B样条曲线曲面网格视图采用OpenGL绘制，基函数视图采用MFC GDI绘制。整个程序采用了MFC单文档、多视图类型。其中B样条相关的属性与操作都封装于BH_BSpline类。-This procedure used the framework OpenGL+ MFC SDI, one B-spline curves and surfaces using OpenGL view grid mapping, function-based view r

可实现B样条的绘制各种图形，贝塞尔曲线，coons曲面等等

B样 绘制,均匀，非均匀，BEZIER，准均匀(Bspline Curve include non-uniform curve and Bezier curve.)
