关键帧01

摘 要
近几年,计算机图像处理技术有了快速的发展,观众对于数字媒体艺术作品的审美能力显著提高,基于三维动画技术的作品逐渐成为动画行业中的主流,成为各个动画从业者研究的热门技术方向之一。三维动画是一种以立体化的方式表现物体运动的艺术,以更逼真、更高效的方式来表现物体的运动行为是其特点之一。关键帧指的是角色或者物体运动或变化过程中的关键动作所处的那一帧,是构成一套完整动作的决定元素,关键帧的优劣直接决定动作的表现力与可信度。竞技运动,即“比赛性的体育活动”。竞技动作具有极强的节奏感与观赏性,适合于作为对关键帧技术进行研究的素材。
本课题以三维动画中跆拳道竞技动作的关键帧设计作为研究对象,采用参照现实竞技动作的研究方法。首先,通过参考专业书籍以及查阅大量文献资料,明确关键帧技术相关概念与技术难点、总结关键帧制作流程规范;其次,结合Maya关键帧技术与现实中的跆拳道竞技参考视频;最终通过实地制作出节奏流畅,动作逼真的三维动画短片来验证三维动画技术在表现竞技动作方面的可行性。

ABSTRACT
In recent years, with the rapid development of computer image processing technology, the audience’s aesthetic ability for digital media works of art has been significantly improved. Works based on 3D animation technology have gradually become the mainstream in the animation industry, and become one of the hot research directions for animation practitioners. 3D animation is a kind of art to express the movement of objects in a three-dimensional way. One of its characteristics is to express the movement of objects in a more realistic and efficient way. Key frame refers to the frame in which the key action of a character or object moves or changes. It is the decisive element of a complete set of actions. The quality of key frame directly determines the performance and reliability of actions. Competitive sports, that is, “competitive sports activities.”. Competitive movement has a strong sense of rhythm and appreciation, which is suitable for the research of key frame technology.
This topic takes the key frame design of Taekwondo competitive action in 3D animation as the research object, and adopts the research method referring to the real competitive action. First of all, by referring to professional books and consulting a large number of literature, the key frame technology related concepts and technical difficulties are clarified, and the key frame production process specification is summarized; secondly, combining Maya key frame technology with the real Taekwondo competition reference video, the 3D animation short film with smooth rhythm and realistic action is finally produced to verify the performance of 3D animation technology in the competition Movement feasibility..
Keywords:key frame technology; competitive action; animation production
