curve_test is a set of 3 programs to demonstrate 3 different kind of

third-order parametric curves: Hemite curve segments, Bezier curve

segments, and Splines. Hemite curves are defined by two endpoints and

two vectors, Bezier curves are defined by four points, and Spline curves

are defined by 4+n points.-curve_test is a set of three programs to demonst rate 3 different kind of third-order Parametri c curves : hermitian curve segments, Bezier curve segments, and Splines. hermitian curves are defined by two en dpoints and two vectors.
