| Abstract: | In this paper, we present an efficient approach to performing motion retargetting on a new creature's skeleton that is generated by taking advantage of hierarchical evaluation. A meta-skeleton is created by means of crossing over two source skeletons. We use the mutation and survival principles to reproduce the next-generation skeleton to accomplish motion transitions in a seamless and smooth manner. In addition to the skeleton construction of a new creature by using the hierarchical evaluation, motion analysis is a required process to preserve the original motion attributes of the source creatures. Spacetime constraints, degree of freedom, and principal component analysis are taken into account in the proposed method in order to prevent unexpected artifacts. The experimental results show that the proposed method enables motion behaviors of the target creature to be shown in between the two source creatures. As a result, the proposed technique can effectively produce a new virtual creature's skeleton with plausible motion data, and is applicable to working for 3D digital games and computer animations. |
