MODIFIABLE QUARTIC AND QUINTIC CURVES WITH SHAPE-PARAMETERS |
|
| Authors: | Wu Hongyi Zhu Gongqin |
| Abstract: | This paper presents a method for creating modificable quartic and quintic curves with shape parameters. The curves can achieve C 2 even C 3 continuity and unify both interpolation and approximation to the control points without solving a system of equations or inserting additional control points. They have the local properties like the cubic B spline. Besides, the quintic curve would be able globally to tend the control polygon. |
| Keywords: | modifiable quartic and quintic curves shape parameters C 2 or C 3 continuity interpolation and approximation |
