WebFirst, we assign a parameter value t i to each point P i. The usual way to do this is to use chord-lengths -- you choose the t i values such that t i − t i − 1 = ‖ P i − P i − 1 ‖. Then you compute x as a function of t. The calculation is the one you already know, but it's just x = f ( t) instead of y = f ( x).

Briefly this means that adding any two splines of a given type produces spline of that given type, and multiplying a spline of a given type by any constant produces a spline of that given type. The dimension of the space containing all splines of a certain type can be counted from the extended knot vector: greater depth in art

"WebThe cubic interpolant P ( x) is shape preserving. The slopes at the x j are chosen in such a way that P ( x) preserves the shape of the data and respects monotonicity. Therefore, on intervals where the data is monotonic, so is P ( x), and at points where the data has a local extremum, so does P ( x). Note " - Cubic hermite splines
