Interpret the evolution of the production process of 3D animation

The development of 3D animation production is an upgrade of the development of computer animation. It is a product of the close integration of technology and art. Compared with flat 2D animation production, Shenzhen 3D animation production also follows the rules of 2D animation production. The difference is that 3D animation proposes The concept of time and space requires that the 3D animation designer have certain technical and artistic qualities in the production process, and we also need to have a more detailed understanding of the following Shenzhen 3D 3D animation production process steps:

三维动画制作


3D animation production

Building a model is the first step in making 3D animation, also called modeling work. In this production process, designers need to use three-dimensional software to perform three-dimensional modeling on the computer based on the story. The modeling process is the process of creating a model. There are two general modeling methods: one is to describe the basic set of animation, then use tools to make the required shape, and finally use related methods to combine the various parts of these models into a complete model, so that the model The establishment can be completed immediately. The second is to use lofting modeling technology, that is, first draw the two-dimensional outline of the object in the animation to obtain the body skeleton of the object, and then place the geometric body on the skeleton to generate the required three-dimensional model.


Make materials and textures;

The model created in the first process belongs to the original carcass, and its shape is similar to the clay tires before the porcelain is fired. Therefore, in the second program of Shenzhen 3D animation production, special "decoration" is required for the model, that is, to create Material map. In order to make the created model more in line with the characteristics of dynamic objects, the designer is required to select appropriate materials to represent the material of the object according to the attributes of the object in the story, so that the color, transparency, and reflectance of the object are in line with the real material of the object. Matching is equivalent to skin grafting for the model. It is also called a sticker, which is equivalent to putting on suitable clothes for the animation object. The designer uses the 3D animation software to paste the corresponding image on the corresponding position of the model, so that the appearance of the produced model is more like a real object.


Third, create lighting.

In Shenzhen 3D animation production, the third procedure is to create lights. Generally speaking, scene lighting is mainly composed of natural light, artificial light, and a combination of natural and artificial light. When making 3D lighting, designers need to understand the type of scene environment in advance, understand the type of environment required by the relevant scene in the storyline, and then determine Main light, auxiliary light, background light, grasp the tone and atmosphere of the scene. Light is an indispensable part of the 3D animation production process. It is not only the main light source of scene lighting, but also an important tool for creating and highlighting the tone and atmosphere of the scene. It can be seen that the appearance design of the overall image of 3D animation is inseparable from the creation of light. Therefore, in the production of three-dimensional lighting, coordinate the cooperation between the three light sources, so as to achieve the initial scene effect with the main light source, to supplement the light to enrich and contrast the depth of field and real effect of the scene.


The modeling of the fourth role and the setting of the framework.

The solid model produced by 3D 3D animation uses model components to build characters, scenes and props, and then generates a 3D model by a computer. Sometimes it is necessary to skip the steps of the solid model, and then create the control points on the 3D model, which can be set by the animator The action of the character. Scenes and characters are colored. The shape of the object depends on the model, and the surface color and texture depend on the coloring. The coloring process of 3D animation is done by "Shaders". Through software like Maya, complex color changes can be made.


Sixth, animation settings.

The so-called animation settings are actually setting key frames on the scene and objects, setting the moments in the animation where the action or scene changes the most as the key frames, and then interpolating by the computer (that is, completing the conversion between key frames). As far as animation control is concerned, the realization of the “moving” state of animation is achieved by using key frames in computer animation production. The same principle is used in 3D animation production. Therefore, more key procedures, namely animation settings, are required.


Sixth rendering

To obtain the dynamic picture of 3D animation, in the 3D animation production software, the last procedure, namely rendering, needs to be completed at this time. The drawing process is the process of calculating and drawing to complete the animation through the program. In this process, the designer needs to input all the information in the scene into the computer, including three-dimensional modeling, texture mapping, lighting information, etc., input into the program for calculation and drawing, and finally draw As a result of the animation, the Shenzhen 3D animation production process can basically be completed after the drawing is completed.
