BA2 Animation - Arcs

 Objects (apart from mechanical devices) often follow a slightly circular path, rather than a straight one. This is particularly evident in the human form, and in animals.

A bad example of arcs in animation would be the original Tekken game. In the cut scenes, character’s joints often move slowly, making the animation look unnatural and odd.

On the other hand, many modern games do this very well. Thinking of Bioshock2, almost everything characters did looked realistic, and natural. Adding greatly to the illusion of life. It seems the quality and realism with arcs, is generally more down to the technical limitations of the time. As time passes, arcs are one of the aspects of animation that tends to consistently improve.
