WebAn intuitive approach to designing spatial C 2 Pythagorean–hodograph (PH) quintic spline curves, based on given control polygons, is presented. Although PH curves can always be represented in Bézier or B–spline form, changes to their control polygons will usually compromise their PH nature. WebDec 19, 2024 · A new method to design a cubic Pythagorean-hodograph (PH) spline curve from any given control polygon is proposed. The key idea is to suitably choose a set of auxiliary points associated with the edges of the given control polygon to guarantee the constructed PH spline has G^1 continuity or curvature continuity.
