Texture on a sphere

Thread view:

Hello NG,

I try to get a Texture on rotating sphere.
When I start my application I just get an unicolored
sphere that is rotating. In the case the link to the
texture is wrong the color of the sphere is white.
With the right texture-link the sphere is blue.
I have try to compare with the Java3d/Demos but I do
not know whats wrong :-(

Now the Sourcecode is following:

public BranchGroup createSceneGraph() {

    BranchGroup ContentBranch = new BranchGroup();
    TransformGroup TG = new TransformGroup();
    TG.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
    ContentBranch.addChild(TG);
    Appearance World = new Appearance();
    Appearance app = new Appearance();
    try{
        texImage = new ava.net.URL("file:../ownpics/world.jpg");
    } catch (java.net.MalformedURLException ex) {
    System.out.println(ex.getMessage());
        System.exit(1);
    }
    TextureLoader mytex = new TextureLoader(texImage, this);
    World.setTexture(mytex.getTexture());
    TextureAttributes texAttr = new TextureAttributes();
    texAttr.setTextureMode(TextureAttributes.MODULATE);
    World.setTextureAttributes(texAttr);
    TG.addChild(new Sphere(0.5f,World));

    [...] // here follows the behavior for the roation

ContentBranch.compile();
    return ContentBranch;
}
