I don't think the issue is an OSG one, but the basic concepts in play. I can't work out how your approach is supposed to work. My best guess to what distortion using a 3D texture would be that you want to convert a vertex position to a new vertex position in the vertex shader using a 3D texture. If it isn't this I haven't got a clue.
