A Blendshape Model that Incorporates Physical Interaction

彬彬

We present a new technique for physically-plausible shape

blending by interpolating the spring rest length parameters

of a mass-spring system. This blendshape method begins

by constructing two consistent mass-spring systems (i.e.,

with vertex-wise correspondence and the same topology) for

source and target shapes, respectively, and setting the two

systems as in their static states. In other words, their edge

lengths equal to the rest lengths of the springs. To create

an intermediate pose, we generate a new mass-spring system

consistent with the source and target ones and set its rest

lengths as linearly interpolated between source and target

based on an interpolation factor  2 [0; 1]. The new pose

is then synthesized by computing the equilibrium given the

interpolated rest lengths. In addition, the mass-spring sys-

tem may interact with other objects in the environment by

incorporating collision detection.

2 The Blendshape Model

We make the assumption that the source and target shapes

have vertex-wise correspondence. To preserve their volumes,

we rst add some additional corresponding vertices inside

the two shapes. Then a common topology is created for the

structure of the volumetric mass-spring systems based on 3D

Delaunay triangulation. Similar to [Choi and Ko 2002], we

used a combination of structure springs and bending springs,

which model the elastic properties of the object's surface and

the bending and

exural properties of the material.
