The ShadowFX library provides a scalable and GCN-optimized solution for deferred shadow filtering. Currently the library supports uniform and contact hardening shadow (CHS) kernels.
The library supports a range of different options:
- Shadow map packing into an atlas or a texture array
- Processing up to 6 shadow maps for a union of lights, cascaded light, or a cube light
- Poisson-distributed and regular sampling patterns
Release Notes
Version 2.0 of the library now supports both DirectX® 11 and DirectX® 12. The ShadowFX API is unified across D3D11 and D3D12, allowing an easy transition to D3D12. Samples are provided for both D3D11 and D3D12 versions.
