. This allows animated interfaces to be created with relative ease, as no specific code for the animation is required by the developer. Core Animation can animate any visual element, and it provides a unified way of accessing

, Core Video, and the other Quartz technologies. Core Animation rendering can be accelerated by a graphics processor (GPU). Animated sequences execute in a thread independent from the main run loop, allowing application processing to occur while the animation is in progress. In this way, application performance is not affected, and animations can be stopped, reversed, or ''retargeted'' while in progress.
