Instance Property

bloomBlurRadius

The radius, in pixels, for the blurring portion of the bloom effect applied to highlights in the rendered scene. Animatable.

Declaration

@property(nonatomic) CGFloat bloomBlurRadius;

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. The bloom effect combines selective brightening and blurring effects; this property controls the blur portion of the effect. A value of zero effectively disables the bloom effect, and higher values result in a broader, softer glow. The default value is 4.0 pixels.

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

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