Usage

From source file:Main.java

static Node displacementMap() {
    int w = 220;//from   w  w w .jav a2  s .  c o m
    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 / 50.0 * 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();
    DisplacementMap dm = new DisplacementMap();
    dm.setMapData(map);

    Rectangle r = new Rectangle();
    r.setX(20.0f);
