Abstract

We present a muscle model and methods for muscle construction
that allow to easily create animatable facial models from given
face geometry. Using our editing tool, one can interactively
specify coarse outlines of the muscles, which are then
automatically created to fit the face geometry.

Our muscle model incorporates different types of muscles and the
effects of bulging and intertwining muscle fibers. The influence
of muscle contraction onto the skin is simulated using a
mass-spring system that connects the skull, muscle, and skin
layers of our model.
