Patent ID: 8180613

Claim:
A computer-implemented arm joint wrinkle simulation method which generates an object with 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 arm joint wrinkles on said object; wherein said object comprises an arm; wherein said arm comprises an upper arm, a lower arm, and an arm joint; wherein said upper arm and said lower arm are connected by said arm joint; wherein an arm joint angle value which indicates the angle created by said upper arm and said lower arm at said arm joint is variable; wherein said arm joint is displayed in a manner covered by a fabric image; wherein when said arm joint angle value indicates a first angle value, a first wrinkle image on said fabric image is generated on or near said arm joint; wherein when said arm joint angle value indicates a second angle value, a second wrinkle image on said fabric image is generated on or near said arm joint; wherein said second angle value is larger than said first angle value; and wherein each of said first wrinkle image and said second wrinkle image is expressed by different tones of a same color.
