Instance Property

bloomIntensity

The magnitude of bloom effect to apply to highlights in the rendered scene. Animatable.

Declaration

@property(nonatomic) CGFloat bloomIntensity;

Discussion

A bloom effect adds a soft glow to highlights (areas of bright color) in the rendered scene, simulating the way bright highlights appear to the human eye or a physical camera in a real-world scene. This property controls the strength of the bloom effect; lower values result in a subtle effect, and higher values create very bright glow. The default value is 0.0, resulting in no bloom effect.

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

To enable this behavior, you must first enable the wantsHDR setting.
