Catmull Rom curves

There is a knitting geometry paper which uses Catmull Rom curves, mathematical optimization, then conversion to Nurbs.

Does Moi do any Catmull Rom Curves?
Are the "obsolete" ?

I've located 200 line javascript programs which do Uniform, Chordal, or Centripetal Catmull Rom 3d curves, so a script might be possible?
Not sure if it is worth spending any time on this?

Moi interp curves, or control point curves can be done instead...

Hi Brian, MoI does not do Catmull-Rom curves. Those are basically an older curve formulation that was replaced by NURBS curves.

They are an interpolating curve so you could use Draw curve > Freeform > "Through Points" to get a similar result.

Thank you Michael.
At this time I will not attempt any Catmull Rom curves.
I'll stick with MoI throughpoints, (interpcurve), and attempt some MoI blending between a knit curve and a purl curve.

One of the Nodeeditor nodes has an option for Catmull Rom (Interpolation?)

It's often used in animation controlling software to generate in-between values with some ease-in/ease-out.
