Screen space ambient occlusion (SSAO) is a computer graphics technique for efficiently approximating the ambient occlusion effect in real time. Temporal SSAO (TSSAO) is a high quality and fast implementation with temporal supersampling technology. Instead of using multiple blur passes to smooth the AO noise, TSSAO will sampling between multiple frames to preserve more detail and it will be faster.
Easy to use. Just add Temporal SSAO compenont to the camera!
Performance of TSSAO is scalable for PC/Mac/Linux/Web/Mobile platforms. It works fine both with forward and deferred rendering path. Besides, it supports VR.
