Artist-Oriented Real-Time Skin Deformation Using Dynamic Patterns

Abstract

Abstract. In this paper, we propose an easy-to-use real-time method to simulate realistic deformation of human skin. We utilize the fact that various skin deformations such as wrinkles, bulging and protruding bones can be categorized into various deformation patterns. A deformation pattern for a local skin region is represented using a dynamic height map. Users of our system specify a region of the body model in the texture space to which each deformation pattern should be applied. Then, during animation, the skin deformation of the body model is realized by changing the height patterns based on the joint angles and applying bump mapping or displacement mapping to the body model. The pattern deformation process is efficiently executed on a GPU.

Modeling for Deformable Body and Motion Analysis: A Review

“…After this learning process, the synthesizer translates the mesh of vertices to the generation of appropriate shape and proportion of the body geometry through free form deformation method. Oshita and Suzuki [53] proposed an easy-to-use real-time method to simulate realistic deformation of human skin. They utilize the fact that various skin deformations can be categorized into various deformation patterns.…”
