Modeling expressive wrinkle on human face

Wrinkles are important for realistic facial animation and modeling because they aid in recognizing human's expressions as well as person's age. Different techniques have been used to generate wrinkles, whether it is fine-scale or large-scale wrinkles. This paper presents a technique on modeling large-scale wrinkles, also known as the expressive wrinkle, on human face by using points instead of triangular meshes. The wrinkle will be modeled on a drawing basis, where users can see the effect directly once the shape and location of the wrinkle has been specified on the 3D face mesh itself. After that, the data involved in modeling the wrinkle are retrieved and processed. A new wrinkle shape function will be introduced to capture the realism of the wrinkle generated where it will be applied during the process.
