Abstract
We present a new skin deformation method to create dynamic skin deformations in this paper. The core
elements of our approach are a dynamic deformation model, an efficient data-driven finite difference
solution, and a curve-based representation of 3D models.We first reconstruct skin deformation models
at different poses from the taken photos of a male human arm movement to achieve real deformed skin
shapes. Then, we extract curves from these reconstructed skin deformation models. A new dynamic
deformation model is proposed to describe physics of dynamic curve deformations, and its finite
difference solution is developed to determine shape changes of the extracted curves. In order to improve
visual realism of skin deformations, we employ data-driven methods and introduce skin shapes at the
initial and final poses in to our proposed dynamic deformation model. Experimental examples and
comparisons made in this paper indicate that our proposed dynamic skin deformation technique can
create realistic deformed skin shapes efficiently with a small data size.
