TressFX11 v2.0 (November 2013)

The TressFX11 sample shows how to use AMD's TressFX hair rendering technology for rendering and simulating hair. TressFX uses volumetric self shadowing, transparency, and antialiasing to render individual strands of realistic looking hair. It also uses the GPU to accelerate the physics simulation of each hair.

Version 2 changes: rendering is now deferred, much improved performance, numerous bug fixes, better self-shadowing, scalability options, modular code, porting guide document included.

TiledLighting11 v1.1 (November 2013)

This sample provides an example implementation of two tile-based light culling methods: Forward+ and Tiled Deferred. Both methods support high numbers of dynamic lights while maintaining performance. They use DirectCompute to divide the screen into tiles and quickly cull lights against those tiles.
In addition to standard point and spot lights, this sample supports shadow-casting lights. It also extends tiled light culling to work with alpha-blended geometry. Finally, virtual point lights (VPLs) can be spawned to approximate one-bounce global illumination, as seen in AMD's Leo Demo.

Version 1.1 changes: documentation updated. Catalyst drivers 13.9 or later include a profile for this SDK sample to ensure MSAA performance is optimal.


Any GeForce 400-series required or newer GF card works both samples due to DX 11 hardware. :)

My GTX 480@stock-reference (GeForce driver 331.65 HQ) gets ~163 fps (1024x768 windowed on desktop 1280x1024) on "TressFX11 v2.0" and ~88 fps (max windowed on desktop 1280x1024) on "TiledLighting11 v1.1" running Win 7 x64 SP1 and i5-2500K@4.5GHz. Both samples use default camera/settings.
