Abstract
Techniques are disclosed for augmenting hand-drawn animation of human characters with three-dimensional (3D) physical effects to create secondary motion. Secondary motion, or the motion of objects in response to that of the primary character, is widely used to amplify the audience's response to the character's motion and to provide a connection to the environment. These 3D effects are largely passive and tend to be time consuming to animate by hand, yet most are very effectively simulated in current animation software. The techniques enable hand-drawn characters to interact with simulated objects such as cloth and clothing, balls and particles, and fluids. The driving points or volumes for the secondary motion are tracked in two dimensions, reconstructed into three dimensions, and used to drive and collide with the simulated objects.
