Hi Srikanth, Your shader just needs to handle the base texture as well as the colour you generate for the height. I can't really teach you all you need to know from a simple post, I have to recommend that you learn a bit more about OpenGL shaders directly from OpenGL books/resources on the topic. The OSG just wraps OpenGL shaders so what you learn from OpenGL resources directly applies.
