摘要
A method and an apparatus for expressing wrinkles of a skin in real time in character animation are provided to apply skin wrinkle data extracted from one skin wrinkle example character model to a general character model. A normal map module(12) previously models examples of necessary faces, interpolates the examples of the faces, and generates a normal map. A bump map module(14) previously models examples of necessary faces, interpolates the examples of the faces, and generates a bump map. A calculation module(16) adds and synthesizes a corresponding weight value to the faces for synthesizing the weight value to the normal map and the bump map, and obtains the last normal map or the last bump map. A rendering module(18) performs rendering by using the normal map or the bump map to which the weight value is adopted, and expresses wrinkles of a character.
