In computer graphics, centripetal Catmull–Rom spline is a variant form of Catmull-Rom spline formulated by Edwin Catmull and Raphael Rom according to the work of Barry and Goldman. It is a type of interpolating spline (a curve that goes through its control points) defined by four control points P 0 , P 1 , P 2 , P 3
Ferguson's Parametric Cubic Curves. The Catmull-Rom Spline is a local interpolating spline developed for computer graphics purposes. Its initial use was in design of curves and surfaces, and has recently been used several applications. This paper presents a simple development of the matrix form of this spline, using only
C -continuous curve is adequate. Catmull-Rom splines, as often referred to in both online and printed literature, are actually a specific instance of a family of splines derived by. Catmull and Rom [1]. These splines exhibit 1. C continuity and have a simple piecewise construction. Relationship to Hermite Interpolation. It seems

Aug 9, 2016 The cubic ?-Catmull-Rom spline curves not only have the same properties as the standard cubic Catmull-Rom spline curves, but also can be adjusted by altering the value of the shape parameter ? even if the control points are fixed. Furthermore, the cubic ?-Catmull-Rom spline interpolation function is

Mar 11, 2003 Catmull-Rom splines have C1 continuity, local control, and interpolation, but do not lie within the convex hull of their control points. Note that the tangent at point p0 is not clearly defined; oftentimes we set this to ?(p1 ? p0) although this is not necessary for the assignment (you can just assume the curve does
