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;
}

Map an image on a Sphere, create the Earth, like this:

public TexturedSphere(java.net.URL url) {
texImage = url;
}
