Well one of the interesting things about com.sun.j3d.utils is that its
source code is available, where as Java3D (last time I checked) the source
code is not availible. On several occasions that source code has helped me
understand quite few things, and even so there are some things I plan to
enhance or to alter their functionality in the future (like Text2D and
NormalGenerator). I cant do that with Java3Ds core API (yet). :)
And seeing as the source code is availble for the utilities I would think
they would easily move to the MacOSX or any platform for that matter that
supports Java3Ds core.

Subject: [JAVA3D] Texture : another area where everybody is using "util"
class
When reading Sun tutorial, you often have the feeling that if you want
to use Java3D, then you absolutely need the com.sun.j3d.utils. So why on
earth aren't these classes in the official Java3D API ?
Looks like there is nothing useful for the developer in that API ;-)
How could we be sure that those external packages (com.sun...) will be
available in all the Java3D implementations (the MacOSX one for
instance, or the next releases) ?
On the other hand do we really need them ?
For instance what is the use of that
com.sun.j3d.utils.image.TextureLoader when it's look like all what we
need to get a javax.media.j3d.ImageComponent2D object (needed to create
a Texture object) is a buffered image which can be get by the usual
Toolkit method
Toolkit tk = Toolkit.getDefaultToolkit();
img = tk.getImage("AnyImage.gif");
try {
MediaTracker tracker = new MediaTracker(this);
tracker.addImage(img, 0);
tracker.waitForID(0);
}
catch ( Exception e ) {}
ImageComponent2D image = new
ImageComponent2D(ImageComponent2D.FORMAT_RGB, img);
So, does anybody understand the interest of the following code proposed
in the tutorial ?
TextureLoader loader = new TextureLoader("stripe.jpg", this);
ImageComponent2D image = loader.getImage();
