Real-Time Dynamic Wrinkles of Face for Animated Skinned Mesh

This paper presents a method to add fine details, such as wrinkles and bulges, on a virtual face animated by common skinning techniques. Our system is based on a small set of reference poses (combinations of skeleton poses and wrinkle maps). At runtime, the current pose is compared with the reference skeleton poses, wrinkle maps are blended and applied where similarities exist. The poses evaluation is done with skeleton’s bones transformations. Skinning weights are used to associate rendered fragments and reference poses. This technique was designed to be easily inserted into a conventional real-time pipeline based on skinning animation and bump mapping rendering.
