The thing is, however, that this is hardly of any use in flightsim (appart from the cockpit model and water visual effects), since from the distance, a player usually see other objects in-game, the normal map works as good, as this feature.
PS On a second thought, this feature also can be used for finer ground surface generation, where even a small bumps can be modeled. |
Oleg also mentioned that hedgerows
might be 'mapped' in some way to give a 3D look, without having to model them. Bomb hole craters too maybe (as has been mentioned in this thread).
The picture: They are the same, but of course the model must be mapped in the correct way for the 3D effect to show...that is the wonder of this new graphics technology. It causes a lot less demand on your system than actual polygon modelling.
I think you need a dX11 compatible graphics card to enjoy the benefits of it.
