I have $n$ curves in the 3d space, which I represented with a certain amount of points.
For every curve $i$, there is a vector $v_i$ with $m$ points which belong to the curve. How can i get the torsion and the curvature of a curve through the vector $v_i$?
I thought about Spline interpolation to fit all curves and after calculate torsion and curvature but i'm not sure of this.
