3D animation is a technique used to create moving images in a three-dimensional space, typically for films, video games, commercials, and simulations. Unlike traditional 2D animation, where objects and characters are represented in two dimensions, 3D animation allows for the creation of objects, characters, and environments that have depth, making them appear more lifelike and realistic. 3D animation is widely used in movies, television, video games, simulations, architectural visualizations, and product design. Its ability to create lifelike or fantastical worlds makes it an essential tool in storytelling and visual communication. Popular software for 3D animation includes Autodesk Maya, Blender, Cinema 4D, and 3ds Max.
