Let`s face it, hair in video generally ranges from the blocky bad Lego hair to just plain awful. That said hair in video games is very difficult to pull off realistically, there`s just so many calculations involved to make it look and behave naturally. Well AMD can now give you a fantastic game hair day with its new TressFX technology.
"Since the dawn of the 3D era, characters in your favorite games have largely featured totally unrealistic hair: blocky and jagged, often without animation that matches your character’s movements. Many games have attempted to disguise the problem with short haircuts, updos, or even unremovable helmets. But why? Simply: realistic hair is one of the most complex and challenging materials to accurately reproduce in real-time. Convincingly recreating a head of lively hair involves drawing tens of thousands of tiny and individual semi-transparent strands, each of which casts complex shadows and requires anti-aliasing. Even more challengingly, these calculations must be updated dozens of times per second to synchronize with the motion of a character."
