This work plays an important role in the creation of 2d animation and 3d animation. In the actual animation modelling design study, we combined with 2 d and 3 d animation in the characteristics of the different aspects of technology and art, respectively to carry out its characteristic research, provide theory support for the development of animation creation.In the current stage of animation creation, it is mainly divided into two forms: 2d animation and 3d animation. Next, we respectively study the characteristics of these two animation forms in the modeling design.In the creation of 2d animation, its main production forms include traditional animation and computer animation. Among them, the traditional animation has also realized the digital process in the production process. In the modeling and design process of 2d animation original painting, its main features include the following points:In the process of 2d animation original painting modeling design, there are high requirements for the designers creative skills. This is mainly caused by the following two reasons. The first is the high requirement of artistic creation. For the creation of two-dimensional animation, its artistic feature is one of its main advantages. And the process of original painting modeling design is a process of creating animation creativity and script content by means of artistic processing. In this process, the designer must have a good artistic level in order to achieve excellent artistic creation. The second is the high demand for painting technology. In the process of original painting modeling design, in addition to the requirements on the artistry of the creators, the requirements on their painting techniques are also very high. This is mainly because the purpose of the animation modeling design is to establish a reference drawing template for the animation production, providing a guarantee for the improvement of the quality of the animation works.In the research, we summarize its artistic characteristics into the following points. First of all, is the art of modelling concise by simple painting and of the shadow of line, color, artistic expression means will be the main characteristics of animation modelling, make it has the characteristics of concise and bright, is the first art characteristic of animation design. Next is the geometric composition of the shape contour. In the design of 2d animation modeling, the geometric composition of circle, triangle and square are generally adopted in the design of modeling contour. The shape of this kind of outline can make the cartoon image have distinct artistic characteristics, and it is also beneficial for the creator to grasp the morphological characteristics of the cartoon image. Again, the smooth lines of the painting, the 浩天教育网（www.hotessay.cn）-专业留学生作业辅导中心浩天教育网（Hotessay）为留学生提供高效、优质的 essay 写作服务overall art resulting in strong exaggeration. In 2 d animation modelling design, designers usually drawing work with fluent line, and can assure the artistic quality of design, but also can improve the look of a whole shape. At the same time, in the modeling design, sometimes the animation modeling will adopt exaggerated artistic means to design. Finally, bright color treatment. In 2 d animation art creation, use bright color processing service for the main body of animation art, improve the animation modelling artistic quality is a major means of 2 d animation design and methods. Among them, the use of color contrast, light and shadow changes and other artistic means for animation plot service is also one of the main artistic means of animation modeling design.Different from the traditional 2d animation modeling design, the new 3d animation in the modeling design process using the technical means and artistic expression have its unique. In our study, its characteristics are divided into the following contents:The modeling and design of 3d animation is mainly completed through the process of modeling and mapping. This gives it the following technical characteristics. First, the use of computer technology. 3d is completed entirely by computer software in the production process, especially in the process of modeling and mapping, which requires a high level of computer technology from the creators. This requirement not only includes the computer operation technology, but also includes the specialized technology of 3d animation production. Second, high requirements for details. Compared with 2d animation, 3d animation requires more attention to details. This requires that the designers of the animation modeling must grasp the details of the modeling characteristics in the design process, and carry out detailed
