I just used an Image with a depth in addition to with and height. That worked straightaway. Note that OpenGL and thus OpenSG still draws 2d-polygons by default, even if they're textured from a 3d-texture. If you want volume rendering, you should look at that. I don't know if the volume rendering system has been ported to 2.0. (I wrote my own shader to render a semi-transparent volume from the 3d texture, but it's potentially a bit tricky.)
