Animations are a series of images or frames that are displayed in rapid succession to create the illusion of motion. Animations can be created using a variety of techniques, including hand-drawn or computer-generated images, stop-motion photography, or a combination of different methods.

Animations can be used for a variety of purposes, such as entertainment, education, advertising, and more. They are commonly used in films, TV shows, video games, and online media, as well as in scientific and educational contexts.

Some of the key techniques used to create animations include keyframe animation, motion capture, and 3D computer graphics. Keyframe animation involves creating individual frames of an animation and then using software to fill in the gaps between them. Motion capture involves capturing the movements of real actors or objects and using that data to animate digital characters or objects. 3D computer graphics involve creating digital objects and environments that can be manipulated and animated in a virtual space.

With the advancement of technology, animations have become more realistic and immersive, making them increasingly popular among audiences.
