Object animation is a form of stop motion animation that involves the animated movements of any non-drawn objects such as toys, blocks, dolls, etc. which are not fully malleable, such as clay or wax, and not designed to look like a recognizable human or animal character.
Object animation is considered a different form of animation distinct from model animation and puppet animation, as these two forms of stop-motion animation usually use recognizable characters as their subjects, rather than just objects like static toy soldiers, or construction toys such as Tinker Toys, LEGO brand bricks (Brickfilm), Lincoln Logs, Erector Sets, Playmobil, etc.
Object animation is often combined with other forms of animation, usually for a more realistic effect (e.g., Model Animation or Puppet Animation to add more complex movement or depth to the characters). For example; A toy car can be animated, but is more often animated with a character easily seen driving the car.
The use of animated objects in film has been present since the early days of cinema.
