From source file:Main.java

@Override
public void start(Stage primaryStage) {
    primaryStage.setTitle("");

    int h = 100;
    FloatMap map = new FloatMap();
    map.setWidth(w);
    map.setHeight(h);

    for (int i = 0; i < w; i++) {
        double v = (Math.sin(i / 20.0 * Math.PI) - 0.5) / 40.0;
        for (int j = 0; j < h; j++) {
            map.setSamples(i, j, 0.0f, (float) v);
        }
    }

    Group g = new Group();
