Animated Surface Pasting

In computer animation, the animator spends a lot of time modeling. Surface pasting is a composition method in which a feature surface is attached to a base surface to provide details on the underlying surface. With surface pasting, the user can quickly and easily model faces and other objects with small details. Thus, surface pasting may be a useful animation technique because it reduces the modeling time. However, it is unclear whether pasted surfaces will have problems such as distortion in animation. In this paper, we generated a key-frame animated short to see how pasted surfaces behave in animation. In general, while pasted surfaces behaved as desired in animation, there are some situations where they behave poorly. Most of these situations can either be avoided or they can be fixed with simple intervention by the animator.
