thank you very much for your answer
I tried using SetUserTransform method, but this is applied in the 
modelview matrix stack, while the "default" perspective transform of the 
camera is always applied...
However, with the ( dirty :-( ) technique that I described in my 
previous post, I finally get what I want...
Yes, it is a dirty way to achieve the result, but I haven't time to 
implement a new class that let the user to manually set  the perspective 
transform
bye
Thank you again
Francesco
