Curves have models {curve functions}. Hyperbolas have curvature, arc length, and separation. Clothoid curves have arc length related to bending. G2-splines have arc length related to bending. B-splines are closed curves. Fifth-degree Cartesian polynomials are closed curves. Polar splines are closed curves.
Three-dimensional curves use ellipsoids, spheroids, cylinders, quartics, and splines and try to find optimum position, orientation, scale, and mathematical function.
Principal component analysis can find axes.
