Deformable Particle Model (DPM)
Contents
DPM Theory
Deformable particles change shape in response to internal and external forces, as shown in Figure 1. To represent the shape of a deformable particle, many degrees of freedom are needed. In two dimensions, we use a discreet parametric representation of an Ns-sided polygon, where 
, is the k-th vertex position.
