Quasi-quintic trigonometric Bézier curves with two shape parameters
2019
In this work, we propose a family of six new quasi-quintic trigonometric blending functions with two shape parameters. Based on these blending functions, a class of quasi-quintic trigonometric Bezier curve is proposed, which has some properties analogous to the classical quintic Bezier curves. For the same control points, the resulting quasi-quintic trigonometric Bezier curves can be closer to the control polygon than the classical quintic Bezier curves. The shape of the quasi-quintic trigonometric Bezier curves can be flexibly adjusted by altering the values of the two shape parameters without changing their control points. Under the \({C^2}\) smooth connection conditions, the resulting composite quasi-quintic trigonometric Bezier curves can automatically reach \({C^2} \cap F{C^3}\) continuity.
