Usage

From source file:SimpleTest.java

public BranchGroup createBackground() {
    // create a parent BranchGroup for the Background
    BranchGroup backgroundGroup = new BranchGroup();

    // create a new Background node
    Background back = new Background();

    // set the range of influence of the background
    back.setApplicationBounds(getBoundingSphere());

    // create a BranchGroup that will hold
    // our Sphere geometry
    BranchGroup bgGeometry = new BranchGroup();

    // create an appearance for the Sphere
    Appearance app = new Appearance();

    // load a texture image using the Java 3D texture loader
    Texture tex = new TextureLoader("back.jpg", this).getTexture();

    // apply the texture to the Appearance
    app.setTexture(tex);//w w  w .  ja va 2 s. c o  m

    // create the Sphere geometry with radius 1.0
    // we tell the Sphere to generate texture coordinates
    // to enable the texture image to be rendered
    // and because we are *inside* the Sphere we have to generate
    // Normal coordinates inwards or the Sphere will not be visible.
    Sphere sphere = new Sphere(1.0f, Primitive.GENERATE_TEXTURE_COORDS | Primitive.GENERATE_NORMALS_INWARD,
            app);

    // start wiring everything together
    // add the Sphere to its parent BranchGroup
    bgGeometry.addChild(sphere);

    // assign the BranchGroup to the Background as geometry.
    back.setGeometry(bgGeometry);

    // add the Background node to its parent BranchGroup
    backgroundGroup.addChild(back);
