Figure 6From: The quartic Catmull–Rom spline with local adjustability and its shape optimizationThe shape-preserving quartic Catmull–Rom spline and the cubic Catmull–Rom spline. In each example, the dotted lines represent the control polygon, the dashed lines represent the cubic Catmull–Rom spline, the solid lines represent the shape-preserving quartic Catmull–Rom spline, and the solid points represent the data pointsBack to article page
