Animation involves using computer software and hardware to turn 2D drawings into moving 3D representations. There are several types of animation including traditional animation done by hand, 2D vector animation, 3D computer animation, motion graphics, and stop motion. Popular 3D animation software includes Maya, 3ds Max, and Cinema 4D, which are used to create visual effects for films, TV, games, and more. Free and open-source options like Pencil and Synfig Studios also provide full-featured 2D animation tools.
