A Multi-resolution Approach for Adapting Close Character Interaction
Abstract and Figures
Synthesizing close interactions such as dancing and fighting be-tween characters is a challenging problem in computer animation. While encouraging results are presented in [Ho et al. 2010], the high computation cost makes the method unsuitable for interactive motion editing and synthesis. In this paper, we propose an efficient multiresolution approach in the temporal domain for editing and adapting close character interactions based on the Interaction Mesh framework. In particular, we divide the original large spacetime optimization problem into multiple smaller problems such that the user can observe the adapted motion while playing-back the move-ments during run-time. Our approach is highly parallelizable, and achieves high performance by making use of multi-core architec-tures. The method can be applied to a wide range of applications including motion editing systems for animators and motion retar-geting systems for humanoid robots.
