Thread: Continuity degree of spline curves?

I'm trying to solve a question that simply asks what the degree of smoothness (I assume this is the continuity degree) is for certain spline curves.

For a cardinal spline and a Kochnaek-Bartels spline:

Degree of polynomial: 2n - 1
Gives continuity degree of: C^(n-1)

For a B-spline:

Degree of polynomial: d - 1
Gives continuity degree: C^(d-2)

Are these correct?

I've tried to find what the continuity degree is for the Bézier curve, but I can't find it anywhere.

A Bezier curve is a cubic spline. d- 1= 3.
