Hi, I have a vector which contains the values of curvature K: at each point of the arc-lenght of the curve corresponds a value of K.
How can I reconstruct the curve from these values?
Thanks

The function can't be solved by just knowing the curvature; the curvature can be expressed as a differential equation, so you'll need to know different points on the curve to fill in as boundary conditions.

I can impose as first boundary condition that the curve starts from zero, but what could I say about the second condition?
