Structuring-Curvature Method and Its Application in Curve Designing

Li Dong; Li Xiaoming(Harbin Institute of Technology)  
This paper discusses the boundary condititons used currently for B-spline interpolation and provides a new method to structure boundary conditition, which is called“Structuring-Curvature Method”. Using this method, the shape of curve at end parts can be changed easily at designers’desire by adjusting the“curvature coefficient”K. A method is given at last which gets the value of“curvature coefficient”K through the tangent direction at end points.
