Dear All:

How can achieve the famous "depth of field" effect  where only a portion 
of a scene is clear with the remaining part blurred/jittered.

I understand I need to use the accumulation buffer and multi-passing but 
how ?

I have alredy looked into the osgmotionblur example and a few other 
opengl ones but my attempts were not quite successful.

Can anyone point me into the right direction? It needs to be done with 
OpenSceneGraph.

Appreciate any help/advice.

Regards,
Janusz
