This paper addresses the problem of designing smooth convex curves in an interactive graphics environment. Our main contribution to the solution of this problem is an easy-to-use and efficient design method using a cubic B-spline formulation in the case of given first derivatives at end-points. This method provides users with an intuitive practical way of handling convex curves based on a set of simple equations and a recursive subdivision manner. Because of the ease of computation and the simplicity of subdivision this method has several obvious advantages such as intuitiveness rapidity and convenience.
