Research On Key Frame Pose Of Figure Motion In 3D Animation

With the development of the times and technology, the 3D animation gradually becomes the mainstream in the film and television animation works, and also,it becomes the object of attention and participation to many animators.Therefore, the research on the 3D animation has become an important part of the animation development. The 3D animation is an art of representing movement, how to create and express motion in the most attractive and effective ways has become the core of the animation performance. Key frame pose is the most critical in a role’s action profile modeling, it is a basic unit to constitute the movement of the overall framework,Key frame pose is merits or not directly decides the success or failure of the action.With figure motion key frame pose in 3D animation as the object of the research,the thesis used combining theory with practice as method of research. This article uses the research method of combining theory with practice. First of all, through the analysis of a large number of literature, we summarize the principle and importance of the role’s key frame pose in the 3D animation. Second, this paper analysis some key links in production process of the current key frame pose,and then extracts the key technologies in production of key frame pose. At the same time, in this article,combining with Maya,the mainstream of 3D animation software,it details analysis and verify the production methods of the key frame pose by the case of drunken sword, and discusses difficulties arising from the production process, and gives corresponding solutions.From the Angle of practice, showing how to complete the key Pose in the 3D animation.In this article,after in-depth research of the key frame pose of character in the 3D animation,we get the following conclusions: there is a certain principle in the production of the key frame pose of character, that is to accord with human body structure of balance principle of kinematics, force the transmission principle and three axis principle.On the basis of these,it also possess fluid dynamic line and clear silhouette; the key frame pose of character is vital importance in the animation, its importance is embodied in the three levels, those are the production technology level, animation performance level and film narrative level; On the set of key frame pose, there are several key technologies, that is the selection of reference action,the extraction and regulation of key frame pose,the final observations of the silhouette;Key frame pose mainly has two major difficulties in the process of production, that is the selection of key frame pose and the judgment of role’s trunk curve form.The difficulty in the selection for key frame pose, the author gives the corresponding method. In this article,through in-depth study of key frame pose, and strive to provide animators with some valuable theoretical guidance, as well as the technical skills and experiences.
