We present a physically-based, elastically deformable particle system model that combines the oriented particles used in surface-only models, and the unoriented particles used in volume-only simulations into a bag of particles. Multiple species of particles and predefined interspecies parameters determine elastic material properties. Model dynamic behavior and global shape are determined by the response of its particle ensemble to (i) volume forces and surface forces and torques, and (ii) orienting and shaping forces and torques derived from a distance map.
