二维计算机动画制作新技术

Developmental Trend and New Technology of 2D Computer Animation

二维动画制作过程中,原画、中间动画的制作耗费了大部分制作时间和人力成本.在简要阐述二维计算机动画技术发展的线索和趋势的基础上,介绍了二维计算机动画制作的两种新技术,骨骼操作动作技术和唇语同步技术,并提出了建立基于骨骼操作动作技术的角色类型及其基本动作的骨骼关键帧动画库的设想.这些技术和设想的实施,有可能大幅度提高二维动画制作中原画和中间动画的制作效率.

In the process of 2D animation producing, the design of its original characters and interim movements takes the majority of time and manpower. This paper describes the clue and trend of 2D animation development about how to improve its making efficiency, as well as introduction of the two new technologies of skeleton animation and lip-language synchronization. Moreover, the suggestion to set up characters and animation library based on skeleton animation technology and its skeleton key frame is also presented.
