A New Rational Quadratic Trigonometric Bezier Curve with Three Shape Parameters

摘要

A rational quadratic trigonometric Bezier curve with three shape parameters is presented in this work. The properties of the curve are studied. The C~0, C~1 and C~2 continuous conditions for joining two constructed curves are discussed. The shape of the curve can be flexibly controlled with shape parameters and weight without changing the control points. Some examples are given.
