Animation is an illusion that is created by quickly cycling through a series of images, each slightly different from the last. The brain perceives the group of images as a single changing scene. In film, this illusion is created by using cameras that record many photographs, or frames, each second. When the frames are played back by a projector, the audience sees a moving picture.
Windows Presentation Foundation (WPF) provides a powerful set of graphics and layout features that enable you to create attractive user interfaces and appealing documents. Animation can make an attractive user interface even more spectacular and usable. By just animating a background color or applying an animated Transform, you can create dramatic screen transitions or provide helpful visual cues.
