The approach of polygon modeling here is to "cut" or convert them into whatever object they want, starting from an existing three-dimensional model. The process of this modeling is particularly similar to the process of kneading clay by hand.

Music: in the three-dimensional animation, most of music parts are background music and scene music interspersed in the animation, the background music is from the accumulation of music materials at ordinary times, and a professional sound studio can also be invited to perform customized creation of the background music. Scene music is usually collocated with three-dimensional animation content and is a complement to the content.
Sound effect: the sound effect is used for further enhancing the reality and rhythm of pictures and environments, and is a good supplement to three-dimensional animation, the sound effect usually comes from sound effect material websites, the websites can provide rich sound effect materials, and different types of sound effects are completed through the combination and matching of the materials.
Designing a shot script based on the file;
specifically, the shot-cut script means that before the three-dimensional animation production link, each shot is designed and processed in a text and drawing mode on the basis of a file, the shots are marked by the way, and a corresponding file is written under each shot. The lens of the three-dimensional animation is mostly a two-dimensional picture, and some three-dimensional pictures can be inserted according to actual conditions.
In the three-dimensional animation, the efficiency of the whole production link can be improved by creating the shot script, so that an animator can complete the animation with actual requirements in the shortest time through the shot script. During the process of creating shot, attention needs to be paid to the following aspects: design of a shot, design of a scene, design of a picture style, and the like.

specifically, the three-dimensional animation is formed by simple geometric drawing to form complex scene drawing, the overall visual experience can be greatly improved by good drawing power and modeling skills, illustrator is mainly used as a drawing tool, photoshop is used as a processing tool, and C4D is used as modeling software.
Drawing a graph: the three-dimensional animation is called Motion Graphic (Graphic animation) and graphics are the main components of the three-dimensional animation. The required graphics are designed according to the actual requirements of the file and the style of the whole animation.
Drawing a character: the drawing of characters is mainly applied to three-dimensional animation of character animation wind, and a set of characters with the same design style are designed according to the file.
Scene drawing: the scene drawing is mainly realized by the software of the scene drawn in the process of creating the shot script;
making a three-dimensional animation based on the file, the sound, the shot script and the material;
wherein the three-dimensional animation production based on the file, the sound, the shot script and the material comprises the following steps:
importing materials;
specifically, the material is the basis of three-dimensional animation production, and the source of the material is mainly material drawing which is performed by taking a shot script as a bluebook in the early stage and comprises different icons, characters, scenes and the like. It should be noted here that in the process of three-dimensional animation, animation is performed in the form of a layer, so that layered import should be taken care of when a material is drawn and imported. In addition, in order to achieve a good visual effect of the whole three-dimensional animation, elements such as textures, lines and the like are also necessary. The combination and matching of the elements make the whole three-dimensional animation more distinctive.
The method comprises the following steps of (1) making three-dimensional animation, wherein the making of the three-dimensional animation comprises graphic animation, character animation and character animation;
wherein, the graphic animation: the three-dimensional animation has the characteristic of agility, and achieves the effect of ornamental value through the combined transformation of different basic figures such as points, lines, circles and the like. The main mode is realized by the combination of key frame animation in After Effects and related plug-ins
Character animation and: unlike other character animations implemented in software such as FLASH, most character animations in three-dimensional animations are completed through C4D.
Character animation: animation is actually the visualization of the documents, but not all documents are suitable for being displayed by graphics, sometimes some text animation is needed to assist the graphics animation, and the two are combined to achieve the optimal effect.
Clipping the three-dimensional animation through preset clipping software;
in the process of three-dimensional animation production, the effect of post-editing is more reflected in that whether the animation can be synchronized with dubbing is checked, so that an animator is required to render and export the animation once every other time point, and the exported animation is imported into Premiere to detect whether the animation is synchronized with sound, so that repeated modification caused by asynchronous sound and painting is avoided. The frames carry a large amount of information, so that it is important to grasp the rhythm of the frames, and the later editing is a key step for grasping the rhythm. The main mode is to find out the problems existing in the animation production process through clipping software such as Premiere and the like, and to feed back and correct the problems.
