Character shading in EA Sports MMA ™ using projected Poisson disk based ambient occlusion
Volga Aksoy, Gerald Phaneuf · 2011
In computer graphics, Ambient Occlusion (AO) is one of the quickest ways to add realism to a scene by approximating the effects of global illumination. While there are many different ways of approximating the effects of AO; Screen Space AO (SSAO) techniques have been utilized by plenty of games as these algorithms take full advantage of the custom fragment shading capabilities of today's GPUs.
