abstract

Animation of articulated shapes, such as humans and animals, is one of the main problems in Computer Graphics and a prospering area of research. Usually, bringing a digital character to life requires a lot of skill and long hours of work from the artist. Recent research in computer animation looks for ways to automate some of the artistic tasks, borrowing techniques from machine learning, physical simulation and more. After a brief introduction on traditional computer animation algorithms, I will discuss a skin deformation framework, suitable for animating arbitrary shapes supplied with an articulated skeleton. The skin animation produced by our system preserves the fine geometric details of the object skin and conforms to the characteristic shapes of the object specified through a set of examples. The system provides the animator with an intuitive user interface and produces compelling results even when presented with a very small set of examples. In addition, it is able to generalize well by extrapolating far beyond the examples.
