Patent ID: 7307633

Claim:
A method for deforming a character model in response to a collision, the method comprising: predetermining a set of skin impulse responses for a set of skin points having positions directly defining a polygonal surface representation of the character model, wherein each skin impulse response defines the displacement of at least a second skin point of the character model in response to the displacement of a first skin point; selecting a first subset of a set of skin points as a first set of skin collision points for a first collision; determining a final collision response for the first collision from the predetermined set of skin impulse responses and the first set of skin collision points; applying the final collision response to the set of skin points; and rendering the surface defined by the set of skin points according to the final collision response to create at least a portion of a rendered image; wherein at least one of the predetermined set of skin impulse responses is adapted to be used to determine final collision responses for two or more collisions.
