What is a 3d movie?
I. Concept
1. 2D movies are high-precision movies with mature technology. By means of creating visual images and combining lenses, we can create moving, vivid and concrete images in the space and time of the screen.
2. The 3D stereoscopic cinema is based on ordinary projection digital movies. In the production of film source, the left and right eye images of the film source are displayed in two ways, and each channel of projection images uses two projectors to project related images. Through polarizing lenses and polarized glasses, the left and right eye images of the film source are projected to the audience respectively.
3-D and 4-D dynamic cinemas-compared with 3D stereoscopic cinemas, they are based on 3D stereoscopic cinemas, with various special effects and professional dynamic seats around the audience.
4, 5D movies contain all the functions of 4D cinema, using seat special effects and environmental special effects, with surreal visual experience and special and exciting effects, and simulating actual events with simulated scenes and special organ settings.
2. viewing experience
1. 2D movie viewers can only see one flat screen in an ordinary movie.
2. 3D movies overlap two images, resulting in a three-dimensional effect. When viewers watch with stereoscopic glasses, they feel immersive.
3D and 4D movies (or 4D movies) are new film and television products based on 3D stereoscopic movies and special effects simulation of the surrounding environment, but they are not four-dimensional spaces in the geometric sense. It is to introduce the effects of vibration, blowing, water spraying, smoke, bubbles, smell, scenery and character performance into 3D movies to form a unique performance form.
These live special effects are closely combined with the plot, and the special equipment of cinema chairs creates an environment consistent with the content of the film, allowing the audience to experience the brand-new entertainment effects brought by the film through the multiple physical senses of sight, smell, hearing and touch, which is immersive, thrilling and exciting.
the 4th and 5D movies add dynamic seats and special environmental effects on the basis of the 3D stereoscopic effect, so that the audience's hearing, vision and touch can achieve the strongest sense of realism, just like being in a movie.
Extended data
3D principle:
People look at the same object with their left and right eyes, and the images formed on the retina are not exactly the same. After the two images are synthesized by the brain, they can distinguish the front and back, the distance and the distance of the object, thus generating stereoscopic vision.
The principle of stereoscopic film is that two cameras imitate the visual angle of human eyes and shoot at the same time, and two projectors are simultaneously projected on the same screen for the left and right eyes to watch, thus producing stereoscopic effect.
When shooting stereoscopic movies, you need to put two camera stands on a special tripod head with adjustable angle, and shoot at an angle that is in line with human eyes.
The synchronization of the two cameras is very important, because even an error of a few tenths of a second will make the left and right eyes feel uncoordinated; Therefore, you must hit the board when shooting, so that you can find the synchronization point when editing.
when showing a stereoscopic movie, two projectors are placed in a certain way, and the two pictures are projected on the same screen point to point in a completely consistent and synchronous manner.
a polarizer must be added in front of the lens of each projector, one is a horizontal polarizer and the other is a vertical polarizer (or diagonally crossed), so that the screen will reflect different polarized light into the eyes of the audience.
When watching movies, the audience should also wear polarized glasses, and the polarization direction of the left and right lenses must be matched with the projector, so that the left and right eyes can filter out the pictures that are not polarized.
only the corresponding polarized light image can be seen, that is, the left eye can only see the picture projected by the left machine and the right eye can only see the picture projected by the right machine. After these pictures are synthesized by the brain, stereoscopic vision is produced.
