Hello!

@Brecht Van Lommel and Matt Ebb:
 Thanks for the answer, it will help me a lot, I will look into it.

This weekend implemented the Phong shader for solidlike volumetrics, so
specular highligths are ready. I uploaded related content to the site.
may be I took some extra time to implement other shaders (would you like
that? let  me know what other shaders will be usefull to have for
volumetrics)
