Hello to everyone,

I have around 200 points to interpolate in order to create a closed cam profile. I used to interpolate the points using cubic splines but that is not smooth enough for my application.
I would like to interpolate a degree higher, that is to say having a linear variation of the third derivative instead of the second one for the cubic spline.
Could someone tell me if that is possible using splines or if I need to use piecewise polynomial interpolation of a degree 5 or 7 ?

I would like to have a profile as smooth as possible not oscillating when moving slightly one point (in order to optimize the profile)

Is there an example of such interpolation somewhere ?

Thanks for your help,

I would use fewer points.
