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. |
If tessellation can be "activated " function of viewing distance it would add a lot of "lifelikeness" to objects like rail ballast and sleepers, road sides, craters, generally man-made objects like houses, buildings...maybe without taxing too much FPS!
I hope professional 3D people will be able to enlighten us sooner or later
