The Research And Implementation Of 2D Animation Technology

With the development of two-dimensional(2D) animation techniques,2D animation has a wide range of applications in many fields of entertainment, advertising, education, etc., and has become an indispensable part of people’s lives. The technology of 2D animation is researched in this paper. It mainly includes three aspects:2D picture vectorization, a method of automatically generating 2D animation Intermediate Frames and coloring, and 3D aided 2D animation rendering method2D vector graphics drawing module can draw vector graphics on the system. It is based on computer graphics research-based, and related to image pre-processing and vector representation. Intermediate frames generated automatically and coloring is based on the gradient of 2D shape, and it iterative matching relations between the obtained enclosed areas of inputting key frame, and then interpolate. At the same time, the color information of the initial key frame is transmitted to the each region of target frame, so as to realize the automatic generation of intermediate frames and coloring. According to the theory of differential geometry and 3D graphics,3D aided 2D animation rendering method detects and draws the three feature lines of the 3D model. It can automatically calculate the occlusion relationship between the before and after frames, and ultimately draws the 3D model to in the 2D animation frames.In traditional 2D animation production process, the production of intermediate frames is one of the most time-consuming and laborious links. By combining practice and theory, the specific algorithm of the method of automatically generating 2D animation Intermediate Frames is given in this paper. It can realize in only provides the starting frame and the termination frame automatically generates the intermediate frame, improve the animation production efficiency. Moreover, it can dynamically adjust space position relations of the 3D object, and automatic project produced stylized volume rendering, this method put forward not only enrich the 2D animation material library, but also improve the reuse rate of 3D model.
