Hi Robert, Thanks for your help. The colour map in the osgvolume.cpp example contains specific colour. I would like to implement full range of colours as possible supported by osg. Any idea what I can do to create a colour map of full range colours. Thanks.

Go have a look at the API, the osgvolume.cpp provides code that does it. This stuff should be realtively straightforward to infer from the code you have in front of you. If you are struggling then perhaps it's time you went back to basics a bit more w.r.t OpenGL and C++ as none of this is particular advanced. I'm happy to point you in the right direction, but it's really not my place to teach you how to program computer graphics applications.
