Polynomial surface fit to points

Hi all,
I seem to remember there was an add on where you could feed a point list and adjust the polynomial fit to the control points for a surface generation. I can’t seem to find the video demonstration so guessing the name is tough. Can anyone point me in the right direction?

I’ll flag this to @DavidRutten who i assume would have an idea of available solutions. Thanks!

Patch component?

Patch is the one with no control of the degrees, I’m looking for a version that can control the poly degree to try different fits.
