OpenGL下通过鼠标动态绘制三次Bezier曲线

程序介绍：



第一次鼠标左键down点为0控制节点， 按住左键移动动态移动确定1控制节点，



第二次鼠标左键down点3控制节点，按住左键移动，确定2控制节点。-OpenGL dynamically through the mouse three times a Bezier curve drawing. program Descr iption: The first time the left mouse button down point 0 control node, hold down the left-moving dynamic movement to determine a control node, the second time the left mouse button down points,3 control node, hold down the Left movement, determine the two control node.
