【摘要】：计算机动画作为计算机图形学与现代艺术相结合的产物,已经在影视、广告、游戏、医学等各个领域获得广泛应用。发展至今,常见的主要有三种类型:关键帧动画、物理驱动动画和数据驱动动画。无论哪种动画制作方法,都离不开角色模型和运动数据两个部分,每一段动画都始于对目标角色进行建模,都终于对运动数据的加载。角色模型节点属性的复杂性使得建模过程繁琐低下,捕获设备成本高昂,且对环境要求过高,捕捉一个动作序列极为不易。人体结构本身的复杂性更使得制作一部自然逼真的动画成为一项耗时耗力的工作,即使借助动画制作软件,对模型和数据进行融合也要耗费大量的时间和精力。因此,了解模型文件和数据文件的格式,借助程序实现自动化融合过程成为了提高计算机动画制作效率的一条出路。本文介绍了计算机动画的制作流程,针对其中最关键的模型文件和运动数据进行探讨解析,了解其文件中的数据存储格式和被调用方式。并依据二者相似的树形组织结构实现自动融合算法,减少该过程的繁琐工作量。最后编码实现仿真系统。
[Abstract]:As a result of the combination of computer graphics and modern art, computer animation has been widely used in film, television, advertising, games, medicine and other fields. Until now, there are three main types of animation: key-frame animation, physical-driven animation and data-driven animation. No matter which animation method, can not do without the role model and motion data two parts, each animation begins to model the target role, and finally load the motion data. Because of the complexity of the attribute of role model node, the modeling process is low, the cost of capturing equipment is high, and the requirement of environment is too high, so it is very difficult to capture an action sequence. The complexity of human body structure makes making a natural animation become a time-consuming and labor-consuming task. Even with the help of animation software, it takes a lot of time and effort to fuse the model and data. Therefore, understanding the format of the model file and data file and realizing the automatic fusion process with the help of the program has become a way out to improve the efficiency of computer animation production. In this paper, the process of making computer animation is introduced, and the most important model file and motion data are discussed and analyzed, and the data storage format in the file and the way to be called are understood. According to the similar tree structure, the automatic fusion algorithm is implemented to reduce the tedious workload of the process. Finally, the simulation system is realized by coding.
