Patent ID: 7386429

Claim:
A computer-implemented arm joint wrinkle simulation method which generates an object with one or more arm joint wrinkles, said method comprising the steps of: (a) retrieving an image of said object from a data storage area, and (b) simulating said one or more arm joint wrinkles on said object; wherein said object comprises an arm; said arm comprises an upper arm, a lower arm, and an arm joint; said upper arm and said lower arm are connected by said arm joint; an arm joint angle value which indicates the angle created by said upper arm and said lower arm at said arm joint is variable; when said arm joint angle value indicates a first value, a wrinkle image of a first length is generated on or near said arm joint; and when said arm joint angle value indicates a second value, a wrinkle image of a second length which is shorter than said first length is generated on or near said arm joint, wherein said second value is larger than said first value.
