Coin3D will have been using the crude 2D Texture axis aligned quad approach that I suggested as an option previously. However, this approach while it might produce a result, it won't perform well or have what I would call an acceptable level of visual quality. The old 2D texture approach is really something that dates back over a decade to when 3D textures didn't exist on common hardware, and is rather a relic on old era of graphics. As a fallback perhaps you could just render an opaque cube and pick out the sides of the cube from the image.
