Adaptive Screen Space Ambient Occlusion

Screen space ambient occlusion (SSAO) is a popular effect used in real-time rendering to produce small-scale ambient effects and contact shadow effects. It is used by many modern game engines, typically using 5 to 10 percent of the frame GPU time. Although several public implementations already exist, not all are open source or freely available, or provide the level of performance scaling required for both low-power mobile and desktop devices. This is where Adaptive Screen Space Ambient Occlusion (ASSAO) fills needed gaps. ASSAO is specially designed to scale from low-power devices and scenarios up to high-end desktops at high resolutions, all under one implementation with a uniform look, settings, and quality that is equal to the industry standard. For more information, refer to the white paperAdaptive Screen Space Ambient Occlusion.
