Cell animations, or commonly known as frame-by-frame animation, refers to the process of creating an animated sequence by drawing individual frames or cells. This technique produces smooth and fluid movements that can be used for various purposes, such as in movies, video games, and advertising. There are various other terms that can be used to describe cell animations, including hand-drawn animations, traditional animation, 2D animations, and classical animations. While the term "cell animation" specifically refers to the use of transparent celluloid sheets to create individual frames, the other terms generally refer to the process of creating frame-by-frame animations using traditional and manual techniques.
