| Abstract: | In this paper, 2m+1 order Ball bases and Ball curves with shape parameters are constructed using recursive equations. They have the same properties as Said-ball bases and curves. Finally, The circle and the vase are generated by 3 order Ball curves with different parameters, and the experiments show the Ball curve shapes can be controlled by adjusting the shape parameters and not need to move the control points. |
