Instance Property

colorFringeIntensity

The blend factor for fading the color fringing effect applied to the rendered scene.

Declaration

@property(nonatomic) CGFloat colorFringeIntensity;

Discussion

Color fringing applies an effect that separately blurs the color components of each rendered pixel, adding subtle rainbow edge effects to the rendered scene that simulate the effects of chromatic aberration in a physical camera. Higher values for this property result in brighter, more vivid color fringing, and lower values create a subtler effect. The default value of 1.0 leaves the color fringing effect at its most vivid.

This property controls a fade between the color fringing effect and the otherwise-normally-rendered image. The colorFringeStrength property controls the breadth of the color fringing effect.

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