Realistic 3D Facial Wrinkles Simulation Based on Tessellation

Realistic wrinkles are important for enhancing the realism of 3D facial expression. In this paper, we proposed a combined method to simulate realistic wrinkles generated in facial expressions. By taking physiological mechanism of facial wrinkles into account, we used the muscle model for facial animation to extract the wrinkle region, and then an improved wrinkle model was applied to generate wrinkles on wrinkle region. In the simulation, we subdivided face model using DirectX 11 Tessellation technique. The experiment results of our combined method demonstrated that it can generate realistic wrinkles on a 3D virtual face.
