摘 要: 在计算机图形学中,角色运动重定向技术对于骨骼动画的广泛应用具有重要意义。为了便于人们了解已有的三维角色运动重定向研究成果并引发进一步的研究,文章首先简要介绍了骨骼动画技术与运动重定向;其次回顾了已有的运动重定向技术,并将其归纳为3类方法,通过对每一类方法进行分析,得出了现有研究在非人形角色和拓扑异构角色之间的运动重定向还很薄弱的结论;最后针对目前研究中存在的问题,展望了未来研究工作的主要方向。 |

Abstract: In computer graphics, character motion retargeting is of great importance to the wide application of skeletal animation. In order to facilitate the understanding of existing research achievements in 3D character motion retargeting and to stimulate further research, the paper first briefly introduces skeletal animation techniques and motion retargeting, and then reviews all major motion retargeting techniques that have emerged so far, categorizing them into three types of methods. By analyzing each category of method, it is concluded that existing research is still weak in motion retargeting among non-humanoid characters as well as topologically heterogeneous characters. Finally, the main directions of future research efforts are envisioned to address the problems of current research. |
