This document provides an introduction to animation, including its definition, thought processes, types, production process, and software/tools used. Animation is defined as the art of movements that are drawn between each frame, rather than what exists in each frame. The key types discussed are 2D, 3D, stop motion, VFX, and experimental animation. The production process involves pre-production, production, and post-production stages. Creative and critical thinking are essential thought processes for animators.
