Detailed Description

Reference implementation of the Scalable Ambient Obscurance (AmbientOcclusion) screen-space ambient obscurance algorithm.

The optimized algorithmic structure of AmbientOcclusion was published in McGuire, Mara, and Luebke, Scalable Ambient Obscurance, HPG 2012, and was developed at NVIDIA with support from Louis Bavoil.

The mathematical ideas of AlchemyAO were first described in McGuire, Osman, Bukowski, and Hennessy, The Alchemy Screen-Space Ambient Obscurance Algorithm, HPG 2011 and were developed at Vicarious Visions.
