What is 3D animation? What is two dimensional, one dimensional? Four dimensional? ）

3D animation is a form of animation based on a 3D model created by computer software. Unlike traditional 2D animation, 3D animation is able to present more realistic and vivid visual effects. In the production process of 3D animation, it needs to go through a series of complex processes such as modeling, material mapping, lighting, animation, and rendering, and the technical requirements are high.

2D animation, also known as 2D animation, is a flat form of animation characterized by the representation of images and characters on a flat surface. Compared to 3D animation, 2D animation is relatively simple to make, but it also has its own unique style and expressiveness.

One-dimensional animation, on the other hand, refers to animation that is represented in one dimension (i.e., left and right or up and down). This form of animation is relatively simple and is usually used to make some simple geometric shapes or text dynamics.

Four-dimensional animation refers to the animation of four dimensions, usually referring to the representation of time and space. 4D animation can achieve a more complex and dynamic effect by adding a time dimension to the 3D animation.

In general, 3D animation, 2D animation, 1D animation, and 4D animation are all different forms of animation, each with its own characteristics and uses.

1. Distinguish from the definition of the four:

1. Definition of one-dimensional space: One-dimensional space refers to the space composed of only points in a line, which only has length, no width and height, and can only be infinitely extended to both sides.

2. Definition of two-dimensional space: Two-dimensional space refers to the plane space composed of only two elements, length and width (x-axis and y-axis in geometry), which only extends to the plane where it is located.

3. Definition of three-dimensional space: Three-dimensional space, in daily life, can refer to the space composed of three dimensions: length, width and height.

4. Definition of four-dimensional space: Four-dimensional space refers to the standard Euclidean space, which can be extended to n-dimensional.

2. Distinguish from the attributes of the four:

1. Properties of one-dimensional space: only length, no width and height.

2. The property of two-dimensional space: there is both length and width.

3. Attributes of three-dimensional space: length, width and height.

4. Attributes of four-dimensional space: three spatial dimensions and one temporal dimension.

3. Distinguish from the scope of application of the four Lu Hui:

1. Scope of application of one-dimensional space: space physics, advanced mathematics.

2. Scope of application of two-dimensional space: mathematics, computer.

3. Scope of application of three-dimensional space: mathematics and physics.

4. Scope of application of four-dimensional space: quantum, cosmic and cosmic science.

2D animation. It is an animation created on a two-dimensional screen. A two-dimensional animation is a picture on a flat surface. Paper, ** or computer screen display, no matter how strong the three-dimensional sense of the picture is, after all, it is only a simulation of the real three-dimensional space effect in two-dimensional space.

Today's computer-generated 2D animation is an improvement on traditional manual 2D animation. Through inputs and keyframes; Calculate and generate intermediate frames; define and display motion paths; Coloring the picture interactively; Produce some special effects; Synchronize the picture with the sound; Control the recording of the movement series and much more.

2D AnimationWhat does 3D animation mean.

3D animation. Also known as 3D animation, it is an emerging technology that has emerged with the development of computer software and hardware technology in recent years. The 3D animation software first establishes a virtual world in the computer, and the designer establishes the model and scene according to the shape and size of the object to be represented in this virtual 3D world, and then sets the movement trajectory of the model, the movement of the virtual camera and other animation parameters according to the requirements, and finally assigns a specific material to the model according to the requirements and lights are added.

When all of this is done, the computer can automatically calculate and generate the final picture.

2D AnimationWhat does 3D animation mean.

The way 3D animation technology simulates real objects makes it a useful tool. Due to its accuracy, authenticity, and unlimited operability, it is currently widely used in many fields such as medicine, education, military, entertainment, etc. In the production of film and television commercials, this new technology has been welcomed by many customers because of its refreshing feeling.

3D animation can be used for special effects production (such as **, smoke, rain, lighting effects, etc.), special effects (crashes, deformations, unreal scenes or characters, etc.), advertising product display, intro flying words, etc.

One: zero-dimensional, one-dimensional, two-dimensional, three-dimensional.

Zero-dimensional space is a point, an infinitesimal point that does not occupy any space, and a point is a zero-dimensional space. When countless points are set and arranged, lines are formed, straight lines are one-dimensional space, countless lines form a plane, and planes are two-dimensional space. Countless planes are juxtaposed to form a three-dimensional space, that is, a three-dimensional space.

Two: The fourth dimension: time.

The three-dimensional world is stationary, when the three-dimensional world changes in time, the four-dimensional space is generated, if time is regarded as an axis, then any point on this axis is a three-dimensional space, that is to say, countless three-dimensional spaces are set according to the time axis, constituting a four-dimensional space.

In the four-dimensional space, time proceeds linearly, although the future cannot be **, but there is only one source, and there is only one future, no matter what will happen in the next second, there is only one future that will happen.

Similarly, if we ignore the 3D properties, we will see that any 4D object behaves as a line segment on the timeline.

Three: Time plane.

What would it make up if an infinite number of timelines were combined?

A plane of time. This plane of time is the five-dimensional space, which is composed of an infinite number of four-dimensional spaces according to a certain axis.

But don't ask me what the criteria for this axis are, because I'm a four-dimensional being, and I can't make a standard for a phenomenon that I can't observe at all.

But we can imagine that an object in a five-dimensional space should span different time axes. On any one timeline, you can only observe a portion of it.

Four: Jumps between timelines.

Suppose a four-dimensional life form wants to jump to other time lines, then it must first become a five-dimensional life form, and obviously, in the process of jumping, it will appear on both time lines at the same time, and then it has met the requirements of a five-dimensional life form.

This fact can be expressed in another sentence: in four-dimensional space, time is linear, and the direction and course cannot be changed. Only in five-dimensional space can you change the direction and course of time.

So: it's not so much that you change history, it's that you change the timeline you're in.

Five: Infinity and eternity.

While humans can imagine the concept of infinity, we cannot see what the five-dimensional world looks like.

While humans can understand the concept of eternity, we cannot create something eternal.

There is no physical limitation of photographic equipment, and the camera in the 3D animation virtual world can be regarded as an ideal movie camera, and the production staff is equivalent to the director, photographer, gaffer, artist, and set, and the quality of the final picture effect only depends on the level, experience and artistic accomplishment of the production personnel, as well as the technical limitations of 3D animation software and hardware.

The production cycle is relatively long.

The cost of producing a 3D animated ad is proportional to the complexity of the production and the degree of realism required, and increases exponentially.

Although the entry threshold for 3D animation technology is low, it takes years of unremitting efforts to master and use it proficiently, and at the same time, it is necessary to constantly learn new techniques as the software develops. It has the highest technical content of all forms of film and television advertising production. Due to the technical complexity of 3D animation technology, it is unlikely that the best 3D designers will be proficient in all aspects of 3D animation.

3D animation is a work that closely combines art and technology. In the production process, on the one hand, it is necessary to fully realize the requirements of advertising creativity in technology, and on the other hand, it is necessary to recreate art in terms of picture tone, composition, light and shade, lens design and combination, rhythm grasp, etc. Compared with graphic design, 3D animation has more concepts of time and space, and it needs to learn from some rules of graphic design, but it is more to create according to the laws of film and television art.

When we talk about four-dimensional space, we are actually three-dimensional space plus time. Just like 3D animation, things are three-dimensional, plus time, to make three-dimensional space move, this is the concept of four-dimensional space.

No matter how you look at a two-dimensional picture, the content of the picture remains the same. In the three-dimensional picture, the scenery in the painting has a front, side and back, and you can see different contents by adjusting the viewpoint of the three-dimensional space.

It should be the realism and three-dimensionality of the animated characters.

For animation, 3D animation should be relatively good, you can think of it yourself, I will consult.

I've never heard of a 1D animation so far; Two-dimensional animation is a paperless animation made by traditional drawings scanned on paper into a computer, flash software, etc., which is a two-dimensional empty kei liquid room, such as the Miyazaki series; Three-dimensional is 3D, Chinese and English, the name is not the same, but the name is not the same as the brother, computer-made, 3D Max or Maya software production, paperless, three-dimensional space three-dimensional animation, such as Dichen Youshiny series, Shrek, Toy Story and so on.

I've never heard of a 1D animation so far; Two-dimensional animation is the traditional paperless animation made by flash software and other paperless animations that are scanned on paper, such as the Miyazaki series; Three-dimensional is 3D, Chinese and English, the name is different, computer-made, 3DMAX or Maya software, paperless, three-dimensional space three-dimensional animation, such as Qingye Disney series, Shrek, Toy Story and so on.
