Abstract: | In this paper, Bézier basis with shape parameter is constructed by an integral approach. Based on this basis, we define the
Bézier curves with shape parameter. The Bézier basis curves with shape parameter have most properties of Bernstein basis and
the Bézier curves. Moreover the shape parameter can adjust the curves' shape with the same control polygon. As the increase
of the shape parameter, the Bézier curves with shape parameter approximate to the control polygon. In the last, the Bézier
surface with shape parameter is also constructed and it has most properties of Bézier surface.
