Anatomically Based Human Hand Model
Irene Albrecht,
This hand model has an anatomical structure, including bones, muscles,
and skin. Bones and skin surface are represented by triangle
meshes. The physics-based hybrid muscle model consists of geometrical
muscles which have an actual geometrical shape enabling them to bulge
during contraction, and pseudo muscles responsible for rotation of the
bones following mechanical laws. A mass-spring system connects skin,
muscles, and bones. Animation of the model is controlled by muscle
contraction values which the muscle model converts into movement of
skin and bones. Resulting animations exhibit anatomically and
physically correct finger movements and skin deformations. New hand
models can be generated from photographs using a feature point based
deformation technique.
