Abstract
An original basis is constructed on the space in this paper.This basis has the similar properties to Bezier basis of the endpoint and interpolation.Then H-Bezier basis is defined based on the space,also the formula of recursion is given when.Next the properties are discussed.Meanwhile H-Bezier curve and H-Bezier surface are defined,the properties of the curve is discussed.Last it is demonstrated that many valuable curves,such as algebraic curves and transcendental curves,can be expressed by H-Bezier curves.
