### Catmull-rom of interpolation technology Spline interpolating

point and end point to form four control points can be. For example, there are now p0,p1,p2,p3, if using [P0,P1,P2,P3] to construct the curve, the curve will only be able to pass through the P1-P2, in order to allow the curve through P0 and P3, we can artificially construct the following control points [2p0-p1, P0, P1, P2], and [P1,p2, P3,2P3-P2]. In this way, you can draw a curve that passes through all the control points.for (int index = 1; index Cgpoint point0 = [self pointatindex:index-1 of

### Implementation of three splineinterpolation curves in unity

Recently need to use interpolation, but always feel that the linear interpolation is worth it too hard, so want to see three times how to do spline curve. There are a lot of articles about algorithms and program implementations. The main purpose of this article is to Help yourself to understand, solidify The existing code is not implemented on the Un

### Double cubicinterpolation of image scaling

Double cubic interpolation of image scaling One: Mathematical Principles If you know a function f (x) and its derivative at x=0,x=1, then the function can be interpolated between [0,1], when the function When expressed as a three-time polynomial, we call the cubic interpolation. A three-time polynomial and its derivati
