How to make a three-dimensional high-definition stereogram

1. Pre-production refers to the planning and design of cartoons before using computers to produce them. It mainly includes: literary script creation, sub-shot script creation, modeling design, and scene design.

Literary scripts, which are the basis of cartoons, require visual expressions of text, that is, the content described in the script can be expressed in pictures. Descriptions without visual characteristics (such as abstract psychological descriptions, etc.) are prohibited of. Literary scripts for cartoons come in various forms, such as mythology, science fiction, folk tales, etc. The content is required to be healthy, positive, clear in thinking, and logically reasonable.

The split-shot script is an important step in further visualizing the text. It is the director’s re-creation based on the literary script and reflects the director’s creative vision and artistic style. The split-shot script has the structure: pictures + text, expressing The content includes lens types and movements, composition and light and shadow, movement methods and time, music and sound effects, etc. Each picture represents a shot, and the text is used to describe content such as the length of the shot, lines and actions of the characters.

Style design includes character modeling, animal modeling, utensil modeling, etc. The design content includes the appearance design and action design of the character. The requirements for modeling design are relatively strict, including standard modeling, face drawings, and structures. Pictures, scale drawings, exploded views of props and clothing, etc., are realized through the design of the character's typical movements (such as several emotional character movements that reflect the character's personality and typical movements), and are accompanied by text descriptions. Beyond Architecture multimedia prompts that the shape should be appropriately exaggerated, the character characteristics should be highlighted, and the movement should be regular.

Scene design is the source of scenery and environment in the entire cartoon. The more rigorous scene design includes floor plans, structural breakdown diagrams, color atmosphere diagrams, etc., which are usually expressed in one picture.

2. Fragment production According to the preliminary design, animation clips are produced on the computer through relevant production software. The production process includes modeling, materials, lighting, animation, camera control, rendering, etc. , which is a production feature of 3D animation.

Modeling is when an animator uses three-dimensional modeling software to draw a character model on a computer based on the previous modeling design. This is a very arduous task in 3D animation. All characters and objects appearing in the scene need to be modeled. The soul of modeling is creativity, the core is conception, and the source is artistic literacy. Commonly used software include 3DSMax, AutoCAD, Maya, etc. Common methods of modeling include: polygon modeling—complex models are represented by groups of small triangles or quadrilaterals (not smooth after enlargement); spline modeling—using several spline curves** *Same as defining a smooth surface, characterized by smooth transitions and no sharp edges or wrinkles. It is therefore ideal for modeling and animation of organic objects or characters. Subdivision modeling - a modeling method developed that combines the advantages of polygon modeling and spline modeling. Modeling is not about accuracy but about artistry, like the dinosaur models in Jurassic Park.

Material mapping, the material is the texture of the material, is to give the model vivid surface characteristics, which are specifically reflected in the color, transparency, reflectivity, reflective intensity, self-illumination and roughness of the object. Mapping refers to pasting two-dimensional pictures onto a three-dimensional model through software calculations to form surface details and structures. For specific pictures to be posted at specific locations, 3D software uses the concept of mapping coordinates. Generally, there are plane, cylinder and sphere mapping methods, which correspond to different needs. The material and texture of the model should be consistent with the object properties in real life.

The purpose of lighting is to simulate natural light types and artificial light types to the greatest extent. The lights in 3D software generally include floodlights (light sources that emit light from all sides, such as the sun, candles, etc.) and directional lights (such as searchlights, flashlights, and other light sources with directional illumination).

Animation, based on the shot script and action design, uses the designed shapes to create animation clips one by one in the three-dimensional animation production software. Changes in actions and pictures are realized through key frames. The main picture of the animation is set as key frames, and the transition between key frames is completed by the computer. Most 3D software represents animation information as animation curves. The horizontal axis of the animation curve is time (frame), and the vertical axis is animation value. From the animation curve, you can see the speed, slowness, and jump up and down of the animation settings. Such as the animation curve editor of 3DSMax. The movement of three-dimensional animation is a technology. The changes in the character's mouth shape when speaking, the expressions of joy, anger, sorrow, and walking movements, etc., must conform to the laws of nature. The production must be as delicate and realistic as possible, so animators must specialize in various things. movement rules. If necessary, you can create animations with reference to the changes in the voice, such as making changes in the mouth shape of the speech according to the voice of the speech, so that the movements and sounds can be coordinated. For changes in human movements, the system provides skeleton tools. Through skinning technology, the model is bound to the skeleton, making it easy to produce movements that conform to human movement patterns.

Camera control, using camera tools in 3D animation software according to photography principles, to achieve lens effects designed in split-shot scripts. The stability and smoothness of the picture are the first elements of using a camera. The camera function is only used when the plot requires it, not at all times.

Changes in the camera's position can also create dynamic effects in the picture.

Rendering refers to drawing a complete picture or an animation by a program based on the settings of the scene, the materials and textures assigned to the objects, lighting, etc. Three-dimensional animation must be rendered before it can be output. The ultimate goal of modeling is to obtain static or animated renderings, which all require rendering to complete. Rendering is usually output as an AVI-like video file.

3. Post-synthesis Post-synthesis of three-dimensional film and television animations mainly involves editing previously produced animation clips, sounds and other materials according to the design of the split-shot script and editing them with non-linear editing software to finally generate animated film and television files.

The production of three-dimensional animation uses multimedia computers as tools and is the product of multiple disciplines such as literature, aesthetics, dynamics, and film art. Practical operations require the cooperation of many people, bold innovation, continuous improvement, close integration with social reality, reflection of people's needs, and advocacy of justice and harmony.

Many people have seen day scenes and night scenes in 3D animation, but do you know what day scenes and night scenes in 3D animation are? Three-dimensional animation films are divided into day scenes, dusk and night scenes according to the time to be expressed. Generally, the day view is the main one, supplemented by the night view. Day scenes in 3D animation films are mainly used to show buildings, house types, garden landscapes, etc.; while night scenes in 3D animation films are generally used to show commercial businesses and some garden landscapes, such as gardens, waterscapes, and riverside scenery with special lighting effects. , the peripheral traffic lines are used to render the atmosphere and play a finishing touch.
