I'm attempting to find the length of a NURBS curve, but I'm not having any luck (I'm also not entirely sure if NURBS are more of a programming thing, I initially asked this question over on Stack Overflow then realised it was probably more appropriate here, I hope it's okay to post it again on another stack exchange?).

I have a NURBS line which is always composed of 3 points, 3 weights, the knot vector, and is of degree 2.

It doesn't have to be 100% accurate, converting into a polyline and working out the combined length of the segments would be fine too.

Does anyone have any suggestions for how to approach this?
