screenSpaceAmbientOcclusionIntensity
The intensity of the screen-space ambient occlusion effect applied in camera rendering.
Declaration
var screenSpaceAmbientOcclusionIntensity: CGFloat { get set }Discussion
Ambient occlusion is an effect that improves material shading by calculating the amounts of ambient light that reach various parts of a surface, creating shadows on parts of a geometry where incoming light is obscured by other parts of the geometry. (You can provide pre-rendered ambient occlusion effects for a material using its ambientOcclusion property.) Screen-space ambient occlusion (SSAO) provides a real-time approximation of this effect for the entire scene viewed through the camera.
The default value of this property is zero, disabling SSAO effects. Increasing the intensity value creates deeper, bolder shadows.
