The mathematical spline is a close analogue of the draughtsmans spline, a long narrow strip of wood or plastic shaped into the required curve form by lead weights called ducks. If the draughtsmans spline is considered as a long thin elastic beam, then Eulers equation yields: where M(x) is the bending moment, E is Youngs modulus, I is the moment of inertia and R(x) is the radius of curvature. For small deflections we can assume: where y denotes the second derivative of the deflection y with respect to x. If the ducks are assumed as simple supports: (a linear function) where A and B are constant, therefore Integrating the above equation twice shows that the physical spline can be described by cubic polynomials between supports: where a, b, c and d are coefficients of the polynomial. B-spline curves are splines in which the vertices of an open polygon toge
