1. A method for determining the collective attributes of a set of hairs, the method comprising:

  • determining a volumetric representation of a hair simulation model, wherein the volumetric representation comprises a plurality of volume elements representing the space occupied by the hair simulation model, wherein at least a first portion of the volume elements each encompasses space including at least two non-colliding hairs of the hair simulation model;

    determining a set of target collective attribute values for at least the first portion of the volume elements of the volumetric representation, wherein each target collective attribute value of the first portion of the volume elements is based on at least non-zero numerical contributions from their respective encompassed two non-colliding hairs of the hair simulation model; and

    determining a set of forces for the hair simulation model from the set of target collective attribute values.
