【摘要】 提出了一种B样条曲线构造,得到了通过控制顶点的二次和三次B样条曲线,这种曲线可通过调整控制顶点进行形状修改并始终通过控制点,又不必作反求计算,修改曲线形状很快,同时又能保证精度更多还原

【Abstract】 The general B-spline curve does not pass the control points. But the B-spline curve can pass the control points when correcting shape of curve. This is Anti-calculate and An equation can be solved. However, it is difficulty to correct shape of curve real-time. In this paper, a new arithmetic about how to get B-spline curve which pass the control points and need not to solve equation, has been proposed. It is easy with the arithmetic to correct the shape of curve real-time.更多还原
