NVIDIA ShadowWorks consists of different technologies to provide cinematic shadows.
HBAO+ is a SSAO algorithm designed to achieve high efficiency on DX11 GPUs.
Advanced Soft Shadows provides a simple interface for adding high quality efficient shadows to games. It improves on PCSS to reach new levels of quality and performance, with the ability to render cascaded shadow maps, and multiple spot lights.
- State of the art SSAO (FullScreen, FlickerFree, ArtifactFree)
- Interleaved rendering
- State of the art soft shadows (PCSS, MVSS, ...)
- Support for cascaded shadow maps
- Simple but powerful interface
NVIDIA ShadowWorks in Game/Demo Examples
Call of Duty: Ghosts
NVIDIA HBAO+ adds realistic Ambient Occlusion shadowing and shading around objects and surfaces that occlude light, with a considerably-higher degree of precision than previous AO techniques.
