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. WebJul 30, 2024 · To calculate the curvature extreme of the proposed PH spline, we take 0.001 as the parameter step to sample the points on the proposed PH spline and calculate its curvature; the largest one is recorded as the curvature extreme, and the corresponding parameter is recorded as the parameter of the curvature extreme point.
