Polynomials^{}Polynomials are surfaces of the form The paraboloid is an excellent example. Spline CurvesSpline curves are often used in design because they make it easy to approximate any smooth shape with a polynomial curve (or a blend of several polynomial curves). A spline curve is based on a collection of control points that determine the shape of the curve, and allow its shape to be adjusted easily. Rational SurfacesA surface is said to be rational if it is a ratio of two polynomials. The serpentine curve is a rational curve. |
