The B-Spline Curve Passing Control Points

LIN Yi~1, XIONG Han-wei~2, LUO Shao-ming~3, ZHANG Xiang-wei~3(1 School of Information Technology, Southern Yangtge University, Wuxi 214036, China; 2. School of Mechano-electronic Engineering, Shantou Univiersity, Shantou 515063, China; 3. School of Mechano-electronic Engineering, Guangdong polytechnic University, Guangzhou 510090, China)  
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.
