Regularity and Convexity of NURBS Curves

摘要：

Determining the regularity,convexity and concavity of NLRBS curves is necessary in computer aided geometric design.In this paper,we convert those problems to the questions relating to polynomials.Then based on properties of algebraic equations and isolation theorem of roots,a simple and practical method for determining those geometric properties of NURBS curves is given.
