This document discusses different types of animation techniques. There are three main types of animation: 2D animation which uses the x and y axes and remains static on the screen, 2.5D animation which adds the z-axis through shadowing and highlighting but images remain two-dimensional, and 3D animation which considers all three axes and allows movement towards and away from the viewer. Some specific animation techniques discussed include cel animation where frames are drawn on clear sheets and compiled, computer animation which focuses on color and layers, and stop motion animation where objects are altered and photographed frame-by-frame to create movement. Common file formats for animation are also listed.
