I. Pre-production, refers to the use of computer production before the animated film planning and design, mainly including: literary scriptwriting, screenplay creation, modeling design, scene design.
Literary script, is the basis of the animated film, the requirements of the text expression of visualization that is, the script describes the contents of the screen can be used to show that does not have the visual characteristics of the description (such as abstract psychological description, etc.) is prohibited. Literary scripts for animated films are in various forms, such as myths, science fiction, folktales, etc., and are required to be healthy, positive, clear and logical.
Sub-shot script is an important step in the further visualization of the text, is the director of the re-creation of the literary script, reflecting the director's creative vision and artistic style, the structure of the sub-shot script: drawings + text, the expression of the contents of the lens, including the type and movement, composition and light and shadow, the movement mode and time, music and sound effects, and so on. Each picture represents a shot, and the text is used to explain the length of the shot, the characters' lines and actions.
Modeling design, including character modeling, animal modeling, artifact modeling design, design content, including the character's appearance design and action design, modeling design requirements are more stringent, including the standard modeling, turn surface diagrams, structural diagrams, scale drawings, props and clothing decomposition diagrams, etc., through the character's typical action design (such as a few with the mood of the character action reflects the character's personality and typical action), and with text description to achieve. And attached to the text description to realize. Beyond the building of multimedia tips modeling can be appropriate to exaggerate, to highlight the characteristics of the character, the movement in accordance with the law.
Scene design is the source of scenery and environment in the whole animated film, the more rigorous scene design, including floor plan, structural decomposition diagram, color atmosphere map, etc., usually with a picture to express.

The second segment production according to the pre-design, the computer through the production of relevant software production out of the animation clips, the production process for the modeling, material, lighting, animation, Camera control, rendering, etc., which is the production of three-dimensional animation features.
Modeling, is the animator according to the previous modeling design, through the three-dimensional modeling software in the computer to draw the character model. This is a three-dimensional animation in a very heavy work, the need to appear in the role and the scene of the object to be modeled. The soul of modeling is creativity, the core is the idea, the source is art literacy. Usually use the software 3DSMax, AutoCAD, Maya and so on. Modeling common ways are: polygonal modeling - the complex model with a small triangular surface or quadrilateral grouped together that (not smooth after zoom); spline curve modeling - with several spline curves **** with the definition of a smooth surface, the characteristics are Smooth transitions, no steep edges or wrinkles. This makes it ideal for modeling and animating organic objects or characters. Subdivision Modeling - A modeling method that combines the advantages of polygonal modeling and spline curve modeling. Modeling is less about precision and more about artistry, as in the case of the dinosaurs in Jurassic Park.
Material mapping, material that is the texture of the material, is to give the model vivid surface characteristics, specifically in the object's color, transparency, reflectivity, reflective intensity, self-luminous and roughness and other characteristics. Mapping refers to the two-dimensional picture through the software calculations to the three-dimensional model, the formation of surface details and structure. For specific pictures to be pasted to a specific location, 3D software uses the concept of mapping coordinates. Generally, there are plane, column and sphere mapping methods, which correspond to different needs. The material and mapping of the model should be consistent with the properties of real-life objects.
Lighting, the purpose is to maximize the simulation of natural light types and artificial light types. Lighting in three-dimensional software generally have floodlights (such as the sun, candles and other light sources emitting light from all sides) and directional lights (such as searchlights, torches and other lighting direction of the light source).
Animation, according to the screenplay and action design, the use of the designed modeling in the three-dimensional animation software to produce an animation clip. Action and screen changes through the key frame to realize, set the main picture of the animation for the key frame, the transition between the key frame by the computer to complete. Most of the 3D software represents the animation information as an animation curve. The horizontal axis of the animation curve is the time (frame), the vertical axis is the value of the animation, you can see from the animation curve on the animation setup of the fast, slow, slow, up and down jumps. Such as 3DSMax animation curve editor. Three-dimensional animation of the movement is a technology, in which the characters speak mouth changes, happy and sad expressions, walking movements, etc., are in line with the laws of nature, the production should be as delicate as possible, realistic, so the animator to specialize in the study of a variety of things in motion law. If necessary, can refer to the change of sound to produce animation, such as according to the voice of the speech to produce the speech of the mouth changes, so that the action and sound coordination. For the human movement changes, the system provides a skeleton tool, through the skinning technology, the model and the skeleton binding, easy to produce the human movement laws of action.
Camera control, in accordance with the principle of photography in the 3D animation software using the camera tools, to achieve the lens effect of the design of the screenplay. Stability and smoothness of the screen is the first element of the use of the camera. The camera function is used only when the plot requires it, not all the time. Changes in camera position can also create a dynamic effect on the screen.
Rendering is the process of creating a complete picture or animation from a program based on the settings of the scene, the materials and textures given to the objects, and the lighting. Three-dimensional animation must be rendered to output, modeling the ultimate goal is to get static or animation effects, and these need to be rendered to complete. Rendering is usually output as an AVI type video file.

Three, post-synthesis film and television three-dimensional animation of post-synthesis, mainly the animation clips, sound and other materials, in accordance with the design of the screenplay, through the editing of the nonlinear editing software, and ultimately generate the animated film and television files. Animation movie and television files.
Three-dimensional animation production is a multimedia computer as a tool, a combination of literature, aesthetics, dynamics, film art and other multidisciplinary products. In practice, it requires multi-person cooperation, bold innovation, continuous improvement, close integration with social reality, reflecting people's needs, advocating justice and harmony.
Three-dimensional animation of the day and night scene many people have seen three-dimensional animation, so you know what is three-dimensional animation of the day and night scene? Three-dimensional animation movie according to the time to show different into: day scene, dusk and night scene. Generally, the day scene is the main one, and the night scene is the supplementary one. Three-dimensional animation film is mainly used to show the day scene of the building, house type, landscape, etc.; and three-dimensional animation film is generally used to show the night scene of the commercial business, part of the landscape, such as special lighting effects of the gardens, water features, riverside pan peripheral along the riverside, peripheral lines, in the rendering of the atmosphere, to play the role of the punctuation.
