//package com.java2s;
import java.awt.Polygon;
import java.util.function.BiFunction;

public class Main {
    public static Polygon createPolygonFromFunction(
            BiFunction<double[], double[], Void> fx, int steps,
            double width, double height, double[] tmp, double tmp2[]) {
        Polygon polygon = new Polygon();
        double dX = width / steps;
        for (int i = 0; i < steps; ++i) {
            tmp[0] = i;/*from  w  w w  .j  a v  a2 s .  c o m*/
            tmp2[0] = dX * i;
            fx.apply(tmp, tmp2);
            double val = tmp[0] * height / 2;
            polygon.addPoint((int) (dX * i), (int) (height / 2 - val));
        }
        return polygon;
