What is four-dimensional animation?

A two-dimensional image is an image on a plane. Two-dimensional animation is an improvement of traditional manual animation. By inputting and editing key frames; Calculating and generating an intermediate frame; Define and display the motion path; Color the picture interactively; Produce some special effects; Realize the synchronization of picture and sound; Control the recording of sports series and so on.

three-dimensional animation

Also known as 3D animation, it is a new technology with the development of computer software and hardware technology in recent years. Three-dimensional animation software first establishes a virtual world in the computer. Designers build models and scenes in this virtual three-dimensional world according to the shape and size of the objects to be represented, then set the motion trajectory of the model, the motion of the virtual camera and other animation parameters according to the requirements, and finally assign specific materials to the model, and light it as needed. When all this is done, the computer can automatically calculate and generate the final picture.

The way 3D animation technology simulates real objects makes it a useful tool. Because of its accuracy, authenticity and unlimited maneuverability, it is widely used in many fields such as medicine, education, military affairs, entertainment and so on. In the production of film and television advertisements, this new technology can give people a refreshing feeling, so it has been welcomed by many customers. Three-dimensional animation can be used to make special effects (such as explosion, smoke, rain, light effects, etc.). ), special effects (crash, deformation, illusory scenes or characters, etc. ), advertising product display, title flying and so on.

Compared with real advertisements, three-dimensional animation advertisements have the following characteristics:

Can complete the shot that the real shot can't complete.

Production is not affected by weather season and other factors.

The technical requirements for producers are higher.

Strong modifiability and easy control of quality requirements.

The shot with high real cost can be realized by three-dimensional animation to reduce the cost.

You can complete the real shooting of dangerous scenes through three-dimensional animation.

Non-reproducible shots can be simulated by three-dimensional animation.

Products that can beautify the display.

There is no physical restriction on the expressive force of the picture, so the camera in the virtual world of 3D animation can be regarded as an ideal movie camera, and the producers are equivalent to directors, photographers, lighting engineers, artists and scenery designers. The final picture effect only depends on the producer's level, experience and artistic accomplishment, as well as the technical limitations of 3D animation software and hardware.

The production cycle is relatively long.

The production cost of three-dimensional animation advertisement is in direct proportion to the complexity of production and the required truth, and it increases exponentially.

Although the entry threshold of 3D animation technology is low, it takes years of unremitting efforts to master and skillfully use it, and at the same time, it is necessary to constantly learn new technologies with the development of software. In all forms of film and television advertising production, the technical content is the highest. Because of the complexity of 3D animation technology, the best 3D designer is unlikely to be proficient in all aspects of 3D animation.

Three-dimensional animation is a close combination of art and technology. In the production process, on the one hand, we should fully realize the technical requirements of advertising creativity; On the other hand, it is necessary to re-create the art in the aspects of picture tone, composition, light and shade, lens design combination and rhythm control. Compared with graphic design, 3D animation has more concepts of time and space. It needs to learn from some laws of graphic design, but it is more created according to the laws of film and television art.

When we say four-dimensional space, we actually mean three-dimensional space plus time. Just like three-dimensional animation, things are three-dimensional, and with time, three-dimensional space is also moving. This is the concept of four-dimensional space.

One: zero dimension, one dimension, two dimensions, three dimensions.

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

Second: the fourth dimension: time

The three-dimensional world is static. When the three-dimensional world changes based on time, four-dimensional space is produced. If time is regarded as an axis, any point on this axis is a three-dimensional space, that is, countless three-dimensional spaces are assembled according to the time axis to form a four-dimensional space.

In four-dimensional space, time is linear. Although the future is unpredictable, there is only one source and one future. No matter what will happen in the next second, there is only one coming future.

Similarly, after ignoring the three-dimensional properties, we will find that any four-dimensional object is represented as a line segment on the time axis.

Three: Time plane

Suppose countless time axes are assembled together, what will it constitute?

A time plane. This time plane is a five-dimensional space, which is composed of countless four-dimensional spaces along an axis.

However, please don't ask me what the standard of this axis is, because I am a four-dimensional life, 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 five-dimensional space should span different time axes. At any time line, you can only observe some of them.

Four: Jump between time axes.

Suppose a four-dimensional life wants to jump to other time axes, then it must first become a five-dimensional life. Obviously, in the process of jumping, it will appear on two time axes at the same time, which has met the requirements of five-dimensional life.

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

So: you didn't change history, but changed your current timeline.

Five: Infinity and Eternity

Although human beings can imagine the concept of infinity, we can't see what a five-dimensional world looks like.

Although human beings can understand the concept of eternity, we cannot create an eternal thing.

Although I can conceive a model of the whole five-dimensional space, I don't know what you, my love, are thinking now.

Although I can't create eternal things, at this moment, my thoughts about you have become eternal.
