The background node can take any kind of geometry. Here's an example
with a sphere which has an image mapped onto its inside. It will be
scaled to infinite size, you can never reach it, plus it seem not to
move relative to the viewport which is really cool.
BoundingSphere backBounds = new BoundingSphere(new Point3d(),
Double.MAX_VALUE);
Background bg = new Background();
bg.setApplicationBounds(backBounds);
BranchGroup backGeoBranch = new BranchGroup();
Sphere sphereObj = new Sphere(1.0f, Sphere.GENERATE_NORMALS |
Sphere.GENERATE_NORMALS_INWARD |
Sphere.GENERATE_TEXTURE_COORDS, 45);
Appearance backgroundApp = sphereObj.getAppearance();
backGeoBranch.addChild(sphereObj);
bg.setGeometry(backGeoBranch);
objRoot.addChild(bg);
java.net.URL bgImage = null;
try {
bgImage = new java.net.URL("file:media/images/bg.jpg");
} catch (java.net.MalformedURLException ex) {
System.out.println(ex.getMessage());
}
TextureLoader tex = new TextureLoader(bgImage, new
String("RGB"), mainFrame);
if (tex != null) {
backgroundApp.setTexture(tex.getTexture());
}
