| Abstract: | The paper constructed the basis function of fourth degree uniform B - spline with double shape parameters. The shape of the constructed spline can be adjusted by changing the shape parameter λ,μ value. The whole curve position is adjusted by changing the parameter λ value. The curve is locally adjusted by changing the parameter μ value. |
