3D games and 3D movies

Well, I accidentally saw someone posting to ask this question. Then, I thought deeply and found that I couldn't understand it either.

Therefore, sort out the information collected on the Internet.

Thx to the authers

3D games and 3D moviesThere is a fundamental difference. 3d movies use the distance between two eyes to bring your glasses into an immersive effect! 3D games only allow you to view the scenes, people, or things in the game from various perspectives! In a sense, it is more difficult for 3D games to be immersive!

Games involve modeling, while movies involve environments and various reasons. The focus of the special effects of the game is modeling and action details, while the focus of film and TV is to make the audience visually feel and lifelike.

The two production methods are different from the use of software. Movies are usually produced after being produced, therefore, there are high requirements for rendering, lighting, and action details-they must be combined with real-time scenes. As for why watching 3D movies with glasses, this is becauseThe reason why human vision can tell the distance depends on the gap between two eyes.. A person's eyes are separated by about five centimeters. Apart from aiming at the front, the two eyes will not look at anything at the same angle. Although the gap is very small, the brain uses this tiny gap through the retina to produce a depth of distance and a stereoscopy. Although one eye can see an object, it is difficult to tell the distance between the object.

However, 3D games need to be produced through various engine modeling software, which is not required by film and television.

About 3D in the game.In layman's terms, 1d, or flat games, refers to games such as Tetris and 90 tanks. The whole game is on a plane, and 2D games are games such as DNF, 3D means that a player-controlled role can view the surrounding environment 360 degrees in any direction in a single space, such as CS?
In fact, we usually do not talk about 1D 2D, but are talking about people, such as first-person shooting games and second-person role-playing games.

3D games change the image dimension from a two-dimensional plane image to a three-dimensional perspective image. What you see is a three-dimensional perspective. Simply put, the image has a stereoscopic effect. 3D movies are visually 3D, and the images you see have a space view.

In fact, when watching a 3D movie, we wear a polarization mirror. The light that follows the grating cannot pass through other directions, and the 3D movie can also be watched without glasses, but it is very fuzzy and uncomfortable to watch. Blu-Ray DVD is a new type of light burning technology. Compared with the current red laser DVD, the shorter wavelength of Blu-ray can make the distance between the time rail and the Light Rail closer, in this way, more optical tracks can be burned on the same disk area to accommodate more content.

Principles of 3D movies

The human eyes are about 6 cm away from each other. Therefore, apart from the objects in front of the human eyes, the two eyes must have different angles, in the brain, this difference can automatically form the difference between upper and lower, left and right, front and back, and distance, thus generating three-dimensional vision. Therefore, if we can make different sides of the same scene and image (with only tiny parallax) to make the eyes look at each side, we can automatically form a three-dimensional image of this scene in the brain. The shooting, production, and projection of 3D movies are the process of simulating human eyes to observe the scenes. It uses two movie cameras to take a picture of the same scene at a distance between two eyes (about 65mm), so as to get a picture from different angles (left and right eye images ), during the screening, the image will be displayed on the screen at the same time, and two overlapping images will appear on the screen. When watching 3D movies, the audience only needs to wear three-dimensional glasses"

【

The use of polarized light is equivalent to filtering between the left and right sides of the glasses. The left and right eyes see different things through the glasses, and the visual difference between the two eyes produces a stereoscopy.

],

This allows the left eye to see the left image, the right eye to see the right image, and then the brain will automatically reproduce as a three-dimensional image at your fingertips.

What is 3D movie?
Currently, in cinemas, we mainly play 3D films with two different principles,

It is represented by an IMAX large screen stereo movie. This technology is the best, that is, the so-called polarized light technology,

During video playback, two parallax images are synchronously displayed using two projectors with a polarized mirror, that is, the images that should be viewed by both the left and right eyes.

Therefore, if 3D polarized glasses are not electrified, what you see on the screen is a duplicate image,

The audience's 3D glasses are two polarized lenses. Through these lenses, our left and right eyes can see the parallax images of the left and right eyes displayed on the screen separately to produce a three-dimensional effect.

The screen of Imax cinema is as high as 70-meter-tall, the image is very clear, the 3D effect is strong, and the sound is also great. It is currently the best in stereo cinema.

The other is a red-blue complementary three-dimensional movie, which was previously used in China, the cinema will send a few yuan to the audience to buy the left red right blue filter glasses,

After the image is taken, the left eye will be able to see the red image on the screen, and the right eye will see the blue image, thus generating a three-dimensional image. This stereoscopic film is much worse than IMAX, And the stereoscopy is somewhat worse, however, the cost is low, and it can also be shown on a normal movie screen,

It can bring more human bodies to the visual magic brought about by three-dimensional movies, and because such movies have no restrictions on the screen,

So we only need to buy a pair of red and blue stereo glasses worth a few dollars to watch the three-dimensional movie on the computer. It's really good.

There is also a common technology, such as the principle of hero stereo glasses, which use time division to turn off the left and right LCD lenses alternately, in contrast, the playback software provided by the game synchronizes and alternately plays the left and right eye parallax images on the screen, so we can see the right and right parallax images respectively. as long as the switching speed is fast enough, we can see a three-dimensional image without blinking.

. Therefore, the requirements for computer monitors are high. CRT monitors are required and the refresh frequency must be at least MHz. However, it is very popular because it is easy to work with computers, hero uses this kind of glasses
