Hello everyone, Lin Fei to answer the above questions for you, 3D projection production tutorial, 3D projection many people do not know, now let us take a look!

Now schools and companies will use one thing, that is, projectors. Go to see a 3D movie with friends and see that the movie player is also a projection. I think all projections are now in 3D, so I went online to check. Sure enough, it would be great if I bought a 3D projector at home, wore 3D glasses, and enjoyed the 3D effect. Here, we take a look at the popular 3D effects and the principles of 3D projectors.

2, 3D projector mainly uses TI DLP Link technology, its principle is DMD chip output picture at 120MHz refresh rate, left and right eyes alternately used, so that the human eye forms 3D"illusion." Its advantages are simple and easy to operate, and the hardware requirements are relatively low. However, in terms of 3D game compatibility, NVIDIA's 3D Vision technology and 3D suite will support more games.

3. Three-dimensional projection principle

TI's 3D projection scheme uses 3D Link technology, which is three-dimensional. It uses a three-dimensional image data format, inserts synchronization pulses between image frames, and does not require a separate external transmitter. By using the fast-switching (120Hz) feature of DMD, glasses can project images synchronously to achieve 3D effects. DLP chips have the property of switching micromirrors very quickly and can present different pictures for the left and right eyes at the same time, thus forming a 3D picture in the brain.

5. Form

As early as the eve of the last World Cup in 2006, many hotels, discos and bars rushed to buy projectors to attract consumers with large-screen broadcasts. Four years later, the phenomenon that the World Cup drives the sales of projectors, televisions and other commodities will be more obvious. Different from 2006, the 2010 World Cup will be broadcast in 3D for the first time, so 3D has become the focus of competition among major manufacturers.

7. DLP glasses

In the actual use of 3D projectors, you need to wear shutter 3D glasses to watch 3D effects.

9. Advantages

3D TVs are expensive. 3D projectors, on the other hand, are much cheaper. Take a 3D projector for example. Now all DLP projectors have been upgraded to 3D, but the price has remained the same or even lower, from more than 4000 yuan to more than 9000 yuan, and then to the high-end more than 20,000 yuan. Projector projection screen size can generally reach 300 inches, far more than 3D TV screen size of 46 inches to 50 inches.

11. Choice and Purchase

The choice of 3D projector depends not only on parameters and price, but also on the manufacturer's 3D application ability, or the execution ability of the program.

In the actual debugging process, such as how to match the 3D projector with PC and graphics card, how to buy the corresponding 3D glasses, how to choose the 3D playback software, how to set the parameters of software and hardware, and even the order of booting before and after, all need the help of experienced engineers to debug good 3D effects. New projectors with 3D decoding function can play 3D movies directly without using software conversion and debugging, and this technology has been applied to miniature projectors.

14, well, the above is to introduce you to the principle of 3D projector. Do you understand? If you want a clear picture, you need to buy an expensive projector. Now many places need 3D effect display for students to practice, which will improve the teaching effect. There are also many places where the main 3D effect. The popularity of 3D allows us to see the world more three-dimensionally. If the compiled software helps you, you'll be happy. I hope everyone will continue to pay attention to us.

This article is finished and I hope it helps everyone.
