Verisimilitude of 3D face modeling can be strongly enhanced by taking into account skin wrinkles. However, there are two difficulties to model real and natural wrinkles: one is the location of wrinkles and the other is the shape of wrinkles. For the first problem, an algorithm for locating wrinkles through extracting feature curves based on photo is presented; For the second problem, a shape control function is proposed considering the properties of real wrinkles, which could provides intuitive parameters for easily modulating the depth and the width of wrinkles, and express the attenuation and impact of one wrinkle on its surrounding surface. The experiment results by applying the method to a 3D face model show that it not only has the advantage of verisimilitude as the photo, but also has the feature of natural ripple which is deeper and wider in the middle than in both sides.
