  • METHOD AND SYSTEM FOR APPROXIMATING CURVE, AND GRAPHIC DISPLAY CONTROL METHOD AND APPARATUS
    Publication number: 20100295858
    Abstract: A method and system for approximating a curve, and a graphic display control method and apparatus are disclosed. The method for approximating a curve comprises the steps of acquiring number information of subdividing points for subdividing a curve needed to be approximated based on coordinate information of control points of the curve, acquiring coordinate information of the subdividing points based on the number information of the subdividing points and the coordinate information of the control points, and connecting the subdividing points with straight lines based on the coordinate information of the subdividing points. The invention could achieve efficient curve approximation and in turn achieve efficient graphic-display control.
