Animation is the rapid display of a sequence of images to create the illusion of movement. Early animation devices included the zoetrope and praxinoscope. In the 1900s, some of the first animated films were created, including "Humorous Phases of Funny Faces" in 1906. Traditional animation involves drawing each frame by hand, while 3D animation uses computer-generated objects that can be rotated and moved in a three-dimensional space. Common animation techniques include traditional, 2D, 3D, motion graphics, and stop motion animation. Popular software used for animation includes Adobe Photoshop, 3Ds Max, Maya, and Cinema 4D.
