A weights maximization method and a method based on the weights of a power exponent form for determining the weights of the rational Bézier curves of degrees are given. The methods are presented according to the Bernstein basis functions and their coefficients. The weights maximization method gives a kind of the weights for arbitrary degree of the rational Bezier curves and generates the curves which preserve the shape of the control polygon better than the Bézier curves. The method based on the weight...
