Requires Unity 5.5.0 or higher.
Volumetric Ambient Occlusion (VAO) is our SSAO plugin for Unity 5 and higher.
容积环境遮挡（VAO）是Unity 5及更高版本的SSAO插件VAO通过模拟柔和的环境光阴影提供额外的视觉质量级别
MAJOR UPDATE - our algorithm now makes use of temporal accumulation to greatly increase both speed and visual quality.
VAO provides additional level of visual quality by simulating soft ambient light shadows. It accentuates local geometric detail and produces shadows by nearby occluding surfaces (in the corners, cracks, holes, rough surfaces etc.). Resulting scenes have more depth and appear more realistic.
VAO captures more detail than classic SSAO solutions and looks more realistic. We have striven to develop ambient occlusion without limitations for the Unity platform. Thanks to the new state of the art algorithm highly optimized for modern GPUs VAO achieves superior performance even for high resolutions.
