保罗·德贝维奇：动态化人物面部表情捕捉

Creating a lifelike digital human face is one of computer graphics’ toughest feats, since people instinctively notice even the smallest flaws. Using a custom face-scanning sphere with 156 LEDs, researchers captured every contour and subtle skin detail in just three seconds. By combining advanced lighting, polarizers, and cutting-edge animation techniques, they produced a digital replica so convincing it fools the eye when it moves. This breakthrough points toward even richer, more believable digital characters for films and games.
