private void evalFunction(double[] approx, ParametricUnivariateFunction function, double[] param) {
    double x;/*from  w  w w. j a  v  a  2  s .  com*/
    double y;
    for (int i = 0; i < contourDataGrid().totalLength(); i++) {
        x = (i / (double) contourDataGrid().totalLength()) * 2 * Math.PI - Math.PI;
        y = function.value(x, param);
        if (Math.abs(y) >= CENTER_COL) {
            continue;
        }
        approx[i * contourDataGrid().width() + ((int) Math.round(y + CENTER_COL))] = 1;
    }
