Research on Computer Aided Design Method of Hand-Painted Art Animation

摘要

The creation of hand-painted animation emphasizes the use of exaggerated techniques to draw animation roles and performance animation role changes in the unique way to abstract the role of artistic features, so that the creation of animation is full of artistic appeal. The traditional hand-painted animation because of its low efficiency of creation, seriously affected the creation of high-quality animation works. With the computer technology widely used in animation creation, around the low efficiency of hand-painted animation, there have been many Computer-Aided Creative hand-painted animation methods. But these methods have several significant problems although can improve the efficiency of animation creation, but reduce the role of artistic expression, it is difficult to highlight the hand-painted animation common abstract exaggeration and other key features. For example, in the creation of hand-painted animation creation of three-dimensional animation technology, based on video streaming animation and reuse of materials used to create hand-painted animation. The introduction of new ideas and new methods, but the low efficiency of animation creation, such as the creation of animation in the introduction of traditional Chinese art elements. With the middle frame method of semi-automatic generation technology to produce animation, which can meet the user to fully express the idea of the heart, in a natural way to define and describe the animation, highlight the role of the art features, but the production efficiency of these methods is still very low. Cartoon role modeling method based on multi view hand drawing. Geometric modeling of role is a key issue in computer role animation. According to the characteristics of cartoon character creation, the role model is expressed as a hierarchical structure which contains grid and skeleton, and the complex cartoon role model is created by combining multi view hand drawing and domain knowledge. Firstly, combined with the surface optimization and surface subdivision algorithm, a grid model matching the multi view hand drawing is created, and then the skeleton subspace model of the grid is established by using the thermal diffusion algorithm. The method adopts the modeling method of batch processing, consistent with the traditional animator’s convention of. Thus, without loss of the artistic features of the animation role, how to effectively improve the animation production efficiency, and provide a good interactive and creative interface for end users, has become a major problem currently facing the development of animation. The research of this paper revolves around how to solve this problem. At present, the research on computer aided animation creation in the semiautomatic generation method of middle frame research and other methods are very different and it not only meet the painters to express the idea of the heart in the definition and description of animated characters, and to highlight the role of abstract art features exaggerated. At present, the main problems of this method are as follows: the correspondence between frames and the interpolation problem between corresponding points are large, poor maneuverability, and the efficiency of animation creation needs to be improved. Based on the intermediate frame generating method, this paper presents an efficient and natural hand-painted animation interactive design method, the algorithm of determining the corresponding relationship between the elements through the key frame, and based on the sequence of the corresponding relationship between the interpolation to generate intermediate frame algorithm, and developed a software prototype to achieve the above algorithm. This method can emancipate painter from time-consuming animation creation, into the animation art creation, the creation of animation art features to highlight the role of abstract exaggerated, and improve the efficiency of animation creation, creation provides the conv
