focalBlurRadius
The maximum amount of blurring, in pixels, applied to areas outside the camera’s depth of field. Animatable.
Declaration
var focalBlurRadius: CGFloat { get set }Discussion
The default value of this property is 0.0, disabling the depth of field visual effect. Changing this property to a nonzero value enables the depth of field effect, in which only objects at a specified distance from the camera appear in sharp focus, and objects nearer to or farther from the camera appear increasingly blurred (up to the amount specified by this property).
You can animate changes to this property’s value. See Animating SceneKit Content.
