Research on Fast Recursive Algorithm for NURBS Curve Interpolation

摘要

According to the NURBS curve interpolation parameters when the n value is very large is not desirable, is ill conditioned coefficient; when the n value is very small it is difficult to describe the complex surface machining problem. This paper introduces a new interpolation algorithm of NURBS curve fast express push, which not only meets the requirements of machining accuracy, but also meets the requirements of real-time, and improves the processing efficiency. Finally, it is proved that the algorithm is correct by matlab7.0, which is consistent with the requirement of NURBS curve interpolation.
