Abstract

A quartic trigonometric BA©zier curve with two shape parameters based on newly constructed trigonometric basis functions is presented in this paper. The curve is drawn by using end point curvature conditions and carries all the geometric features of the ordinary quartic BA©zier curve. The presence of shape parameters provides an opportunity to adjust the shape of the curve by simply altering their values. The G^2 and C^2 continuity under appropriate conditions is achieved by joining two pieces of trigonometric curve.
