TressFX Hair

The TressFX library implements AMD’s TressFX hair/fur rendering and simulation technology. The TressFX technology uses the GPU to simulate and render high-quality, realistic hair and fur. TressFX makes use of the processing power of high-performance GPUs to do realistic rendering and utilizes DirectCompute to physically simulate each individual strand of hair.

Highlights GCN-optimized rendering and simulation Hair and fur support, with high quality anti-aliasing Animation/skinning support Two options for order-independent transparency Maya plugin provided for authoring Full source code provided

New in TressFX 4

Hair is skinned directly, rather than through triangle stream-out. Signed distance field (SDF) collision, including compute shaders to generate the SDF from a dynamic mesh. New system for handling fast motion. Refactored to be more engine / API agnostic. Example code includes compute-based skinning and marching cubes generation. DirectX 12 support, with an example for async compute
