Physically-based surface modeling using flexible wire frames

Introduces a technique to model the structures and behaviors of flexible, elastic objects. The authors use an imaginary elastic wireframe, which is made of membranous, thin-plate type material, to model the surface structures of flexible objects. They demonstrate that in computer vision research a variety of existing shape reconstruction techniques can be unified into the model by expressing shape constraints as potential energy functions on a flexible image plane. In graphic animation, the authors allow deformation sequences to be generated automatically, between prespecified key frames, the surface structures of which are described by the flexible model. Furthermore, they allow collisions of objects´ trajectories so that the interactions of multiple flexible objects can be simulated.<>
