It's seriously all Greek to me, but it looks rather brilliant. The hair also responds to gravity, wind and other environmental facets convincingly and should go a long way in creating more believable avatars moving forward.

DirectCompute is additionally utilized to perform the real-time physics simulations for TressFX Hair. This physics system treats each strand of hair as a chain with dozens of links, permitting for forces like gravity, wind and movement of the head to move and curl Lara's hair in a realistic fashion. Further, collision detection is performed to ensure that strands do not pass through one another, or other solid surfaces such as Lara's head, clothing and body.
