Graphical Modeling and Animation of Brittle Fracture

In 1998, the use of simulated motion in several commercial animations demonstrated that passive simulation is a powerful technique for animating secondary motions. This paper augmented techniques for simulation of flexible objects including models for crack initiation and propagation in three-dimensional volumes. By analyzing the stress tensors computed over a finite element model, the simulation determines where cracks should initiate and in what directions they should propagate.

A Morphable Model for the Synthesis of 3D Faces
A new technique for modeling textured 3D faces. Three-dimensional faces can either be generated automatically from one or more photographs, or modeled directly through an intuitive user interface. Users are assisted in two key problems of computer-aided face modeling. First, new face images or new 3D face models can be registered automatically F/X by computing dense one-to-one correspondence to an internal face model. Second, the approach regulates the naturalness of modeled faces, avoiding faces with an "unlikely" appearance.

Teddy: A Sketching Interface for 3D Freeform Design
A sketching interface for quickly and easily designing freeform models such as stuffed animals and other rotund objects. The user draws several 2D freeform strokes interactively on the screen, and the system automatically constructs plausible 3D polygonal surfaces. The system supports several modeling operations, including construction of a 3D polygonal surface from a 2D silhouette drawn by the user.
