Instance Property

colorFringeStrength

The magnitude of color fringing effect to apply to the rendered scene.

Declaration

var colorFringeStrength: CGFloat { get set }

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 create a more pronounced color shift, creating wider rainbow fringes; lower values spread colors across shorter distances, creating a subtler effect. The default value of 0.0 disables the color fringing effect entirely.

This property controls the breadth of color fringing. The colorFringeIntensity property controls the blend factor between the color-fringed and the otherwise-normally-rendered image.

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