Webb环境光遮蔽（Ambient Occlusion）“AO”为Ambient Occlusion的缩写，中文译为环境光遮蔽。在DirectX 10.1 API推出后，Amblent Occlusion升级为SSAO（Screen-Space Ambient Occlusion:屏幕空间环境光遮蔽）；而在微软推出DirectX 11 API后，SSAO升级至HDAO(高解析度环境光遮蔽：High Definition Ambient Occlusion)。我们有必要对AO（环境光 ... Webb在2007年，Crytek公司发布了一款叫做屏幕空间环境光遮蔽 (Screen-Space Ambient Occlusion, SSAO) 的技术，并用在了他们的看家作孤岛危机上。这一技术使用了屏幕空间场景的深度而不是真实的几何体数据来确定遮蔽量。这一做法相对于真正的环境光遮蔽不但速度快，而且还能获得很好的效果，使得它成为近似实时环境光遮蔽的标准。 SSAO背后 …
