Dear,
i use "Eclipse IDE for Java Developers" but when i compile it and run in on my galaxy s3, it has an error and close.

Dear EgonOlsen,
i have run it, but now i have a code like this:
box = Primitives.GetBox(13f, 2f);
            box.Build();
            world.AddObject(box);
            world.SetAmbientLight(0, 255, 0);
            camera.SetPosition(50, -50, -5);
            SimpleVector p1 = new SimpleVector(1, 1, 1);
            camera.LookAt(box.GetTransformedCenter(p1));
            world.SetCameraTo(camera);
            try
            {
                buffer = new FrameBuffer(100, 100);
            }
            catch (Exception ex)
            {
                button.Text = ex.Message;
            }

it has an erro in buffer creation, do you have an easy example to show the basic box?
