Usage

From source file:ExDirectionalLight.java

public Group buildScene() {
    // Get the current color and direction
    Color3f color = (Color3f) colors[currentColor].value;
    Vector3f dir = (Vector3f) directions[currentDirection].value;

    // Turn off the example headlight
    setHeadlightEnable(false);//from ww  w .ja v  a 2s  .  co m

    // Build the scene group
    Group scene = new Group();

    // BEGIN EXAMPLE TOPIC
    // Create influencing bounds
    BoundingSphere worldBounds = new BoundingSphere(new Point3d(0.0, 0.0, 0.0), // Center
            1000.0); // Extent

    // Set the light color and its influencing bounds
    light = new DirectionalLight();
    light.setEnable(lightOnOff);
    light.setColor(color);
    light.setDirection(dir);
    light.setCapability(DirectionalLight.ALLOW_STATE_WRITE);

    light.setInfluencingBounds(worldBounds);
    scene.addChild(light);
    // END EXAMPLE TOPIC

    // Build foreground geometry

    // Add anotation arrows pointing in +-X, +-Y, +-Z to
    // illustrate aim direction
