Hi Kim, Probably the easiest way would be to render the scene using a render to texture Camera and use a texture for the colour buffer and the depth buffer. Then in a second pass as HUD Camera and render the colour texture directly as a quad on the left hand side, then render the depth texture as a grey scale on a left hand quad.
The osgdistortion example probably comes closest to doing this type of thing w.r.t RTT Camera and HUD Camera setup. Robert.
