Hi Tim. Texture2D and TextureRectangle are wrappers around two distinct types of OpenGL textures, and at a C++ level are both subclassed from osg::Texture, so there is no OpenGL level mapping that makes sense in attempting to convert one to the other, and at the C++ level there isn't any means for casting one to the other, there are different end of storty.
I really no clue as to why you are thinking that this "cast" might be appropriate or useful, but it's not even close to something that is either possible or useful. The best we can do is ask you to take a step back and tell us what the problem you have. Robert.
