Instance Property

aperture

A factor that determines the transition between in-focus and out-of-focus areas. Animatable.

Declaration

@property(nonatomic) CGFloat aperture;

Discussion

Objects at distances from the camera outside its depth of field (specified by the focalDistance and focalSize properties) appear increasingly blurred (up to the value of the focalBlurRadius property). Aperture controls the abruptness of the transition between sharp and blurred—a low value specifies an abrupt transition, and a higher value specifies a gradual transition. The default aperture is 0.125 (or 1/8).

You can animate changes to this property’s value. See Animating SceneKit Content.
