WebJul 19, 2024 · 1 Answer. I'm not an expert Hermite Splines by any stretch of the imagination, but from what I've seen is that the expected behavior would be to interpolate between the second and third point. It looks to me like you just hardcoded in each coordinate to your Get function, so it makes sense that you only get a single interpolation … WebIf each polynomial segment has degree 3, the spline is called a cubic spline. If each segment is described by its ending positions and derivatives, it is said to be in "Hermite" form. The b-spline approach gives a convenient way of ensuring continuity between segments. In fact, you can show that every spline can be represented in b-spline form. dutcher brothers https://on-am.com
