Why is everything in three-dimensional space limited and infinite?

First of all, talk nonsense: 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: instead of changing history, you 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.

Three-dimensional interpretation'

Three-dimensional animation corresponds to two-dimensional animation. Two-dimensional animation is flat, with only the movement effect of up, down, left and right. Three-dimensional animation also has the movement effect of front and back (depth), so it increases the sense of three-dimensional sense and space.

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.

Market Report on the Development of 3D Animation Industry

Market Report on the Development of 3D Animation Industry

3D animation industry is a new industry. Indeed, 3D animation is very promising. Looking at the development of 3D animation, I believe that in the near future, 3D will enter thousands of households, and it will no longer be the monopoly patent of big film studios and professional film and television production companies. In recent years, more and more people are doing 3D and learning 3D, and the trend of 3D platform is changing from high-end to low-end. Without hundreds of thousands of workstations, ordinary home computers can also make very professional 3D works. The charges for 3D animation are becoming more and more reasonable. In the past, the sky-high price of 20,000 yuan/second (advertising standard version) has reached 500 yuan/second, and the 3D architectural and indoor renderings have also dropped a lot. I want to make a fortune by making 3D a virtual fantasy. With the recession of domestic film industry and the impact of foreign blockbusters, how to effectively improve the creative and production level of Chinese people and standardize production standards is a problem that cannot be underestimated in front of peers.

We are faced with opportunities and challenges. How will our development blueprint be planned? It depends on the joint exhibition of senior experts from all walks of life.

First of all, the goals of three-dimensional producers in our industry are not uniform, and there are the following:

1 artistic style, many domestic masters are fascinated by the amazing effects of Hollywood blockbusters from curiosity to hobbies, and strive to improve the level of domestic digital imaging. However, due to the limited conditions, limited capital and technical channels, the dream can not be realized. Or because the film market is depressed, the investment is insufficient, the talents are not concentrated, and they are unwilling to be "licensed" and can't make money.

Making money, 3D animation is a new product, with charming charm and unlimited development prospects, attracting countless explorers to enter the market for gold. Most of them have no art foundation. With amazing acceptance, they learned all the three-dimensional software, and made a lot of money from hardware monopoly in the early stage of the industry, but they are about to face the creative impact and price impact of countless newcomers.

Amateur, it is undoubtedly a good thing to have more enthusiasts to join our cause, but everyone has different factors leading to uneven level. They want to do it well, but there are no conditions! What is even more helpless is that some of them are forced to rush out of the market with low-priced and inferior animation products in order to survive and adapt to fierce commercial competition, resulting in a vicious circle of irregular industries.

Money is earned, food is eaten, and skills need to be improved. What should colleagues do to make the cake bigger together? The space before us is vast, and we have many opportunities:

The traditional industry and agriculture of 1 is no longer the main demand of the people. On the premise of adequate food and clothing, spiritual food is the primary demand of the people. Have you found that modern young people can't live without game consoles, and three-dimensional games won't stop, such as panoramic ring games, and there will be great room for development (making money).

Future movies will no longer be just "flat" screens, but will appear in the form of three-dimensional virtual glasses or panoramic screens, which depends on the passion of three-dimensional artists!

More than 3 are high-end markets, and it is difficult for individuals to produce by teamwork. Let's talk about the three-dimensional needs of ordinary individuals. "Interactive virtual" will be the mainstream way of communication between people in the future. With the rise and popularity of the Internet, there will be perfect 3D browsers, 3D websites, 3D stores, 3D ICQ, 3D chat rooms, 3D online dating and so on. These are the paradise for our individual producers to perform! At that time, there will be countless three-dimensional stores. What to buy? Who will make the products? Whoever does well sells fast! Everyone can make countless three-dimensional beauties and three-dimensional handsome guys, which can be sold to "dinosaurs" and "frogs" each 10! Three-dimensional "Mercedes-Benz" and three-dimensional "BMW", 38 yuan 50 cents buy one get one free!

This is a great opportunity for us to make money!

In that case, I'm afraid even the son of the factory director and the aunt and nephew of the village party secretary will come to learn 3D! It's really tempting.

But then again, the current reality is not optimistic:

1 Let's talk about the game first. Piracy is so serious. After years of hard work, people stole it and didn't make any money. Who will do 3D again?

Virtual movies are difficult to pirate and expensive to make (100 yuan for you to do what you do? It is difficult to find people to invest at present.

Internet has not been popularized in China, and it is conservatively estimated that it will take several years. Stop dreaming! Are you going to eat northwest wind in recent years? Maybe our future will be:

Scene 1:

On the lamppost of the main street, next to the IC phone of China Telecom, and in front of the advertising glass of the back stall, there are several small labels scattered:

Zhongnan Securities Company-Acting for all kinds of ID cards, diplomas and passports for going abroad.

Star entertainment company-long-term urgent recruitment of male and female public relations, 16-25 years old, unlimited experience, specially trained, with a monthly salary of 20 thousand!

Three-dimensional animation-5 yuan every second, door-to-door, electricity: 13245678900 days!

Scene 2:

There is a "popular three-dimensional animation chain store" next to the fine charcoal painting shop. Dialogue:

"Lao shifu! Make a three-dimensional LOGO for my barber shop. "

"all right! Please pay 5 yuan and get it in half an hour. "

-

"Lao shifu true skill! Reward you 10, keep the change! "

"Thank you, thank you, come again next time."

The ultimate scene:

An old man wrote at the bottom of the overpass:

I used to make a living by 3D animation, and I couldn't bear to spend countless money chasing computer upgrades. I devoted my life to creating 3D animation, but the market was ruthless, the Internet dream was shattered, and I went bankrupt and begged for food. I hope your uncles and sisters can donate some money to buy bread. -
