Microsoft DirectX is the graphics technology powering today’s most impressive games. The latest version, DirectX 11, enables the addition of advanced effects and features in NVIDIA-enhanced titles, ranging from tessellation and HBAO+, to Percentage Closer Soft Shadows and NVIDA HairWorks.
In recent years, NVIDIA has been at the forefront of DirectX 11, developing new features and effects that dramatically enhance the games you know and love. And thanks to NVIDIA’s industry-leading GeForce GTX GPU technology, each feature runs best on NVIDIA-powered PCs.
NVIDIA HairWorks
Traditionally, fur and hair in games is created by adding polygon strips and transparent textures to a character. Though this is a simple and cheap implementation, the resulting fur and hair appears completely static and visually uninteresting. With dynamic fur and hair, hundreds of thousands of hair strands can be added to characters, each reacting realistically to a character’s movements and external forces. These dynamic hairs also allow for richer color gradients, and interact with light and shadows more naturally than was previously possible. World and local lighting permeates through each layer, with the deepest layers being naturally shadowed, significantly improving image quality.
Using DirectX 11 technology, NVIDIA has developed NVIDIA HairWorks, a platform agnostic tessellated hair technique that adds dynamic volume in place of static meshes comprised solely of detailed textures. In Call of Duty: Ghosts, the first title to feature NVIDIA HairWorks, the protagonist’s dog is seen without body armor, resulting in the rendering of 470,000 individual hairs, which create an accurate, realistic simulation of a German Shepherd.
