Hi Clement, I can't really make much sense from your post so can't make any specific suggestions.
General comments I would add are that different graphics hardware supports different Texture3D resolution, you have to keep within this to be able doing volume rendering. Also if you don't set up the osg::Image correctly then you'll have problems too - garbage in, garbage out. Robert.
