摘要：
Analogous to the quadratic B-spline curve, a piecewise quadratic trigonometric polynomial curve is presented in this paper. The quadratic trigonometric polynomial curve has C(2) continuity, while the quadratic B-spline curve has C(1) continuity. The quadratic trigonometric polynomial curve is closer to the given control polygon than the quadratic B-spline curve.
