Can anyone tell me the history of 3D? 10

There was a 3D movie in 199x, and there was no fire at that time, mainly because there were no computer special effects at that time, and the picture was not delicate, but it was indeed possible to achieve 3D movies, and it was possible to use polarized glasses, but it didn't seem to be very good for eyesight.

The earliest stereoscopic films: At the end of the 19th century, William Fryce Green of England invented the world's first set of projections and **3D

He projected two images on the screen at the same time, and the audience gained a three-dimensional sense by wearing glasses.

The earliest formal stereoscopic film: MGM's 1936 series of "Audioscopiks" based on the principle of red and green color filters, give.

The audience was given red and green glasses, and the effect was shocking at the time, and the film also won the best Oscar that year.

Nomination for the Short Film Award.

Later: In 1962, Tianma Film Studio invested in the filming, and the famous comedian Chen Qiang starred in "The Adventure of the Magician".

The first 3D film in China. It's just that although 3D movies have a history of many years, they have never become popular.

Note the mainstream. Result: Until 2009, the emergence of an American 3D blockbuster "Avatar" with a global box office of 2.6 billion was shocking.

At the same time, the world has also set off a 3D craze around the world.

Hello, 3D is the abbreviation of three-dimensional, which is three-dimensional graphics. To display 3D graphics in a computer means to display a three-dimensional figure in a flat surface. Unlike the real world, where there is a real three-dimensional space, there is a real distance space.

The computer just looks like the real world, so the 3D graphics displayed on the computer just make people look like the real thing. One of the characteristics of the human eye is that it is near and far small, and it will form a three-dimensional effect. The reason why we can enjoy a three-dimensional image that is really like a real thing is because the difference in color gray scale when displayed on the computer screen makes the human eye have a visual illusion, and the two-dimensional computer screen is perceived as a three-dimensional image.

Based on the knowledge of color science, the protruding part of the edge of a three-dimensional object generally shows high brightness, while the concave part is dark due to the obscuration of light. This understanding is widely used to draw buttons and 3D lines on the web and in other applications. For example, if you want to draw 3D text, you will display a high-brightness color in the original position, and outline it with a low-brightness color in the lower left or upper right position of the comic booth, so that the effect of 3D text will be visually generated.

In the specific implementation, two 2D text of different colors can be drawn in different positions with the exact same font, and as long as the coordinates of the two characters are appropriate, it is completely possible to produce 3D text with different effects visually. Hope mine can help you.

D is the prefix of English dimension, and 3D refers to three-dimensional space. Internationally, Oak Yuxin uses 3D movies to represent three-dimensional films. There are many forms of 3D stereoscopic film production, among which the polarized glasses method is widely used.

It uses two side-by-side cinema cameras, representing the left and right eyes of the human eye, to simultaneously shoot two cinematic images with slight horizontal parallax. During the projection, the two movie films are loaded into the left and right movie projectors respectively, and two polarizers with polarization axes at 90 degrees to each other are installed in front of the projection lens. The two projectors need to run in sync and project the picture on the metal screen at the same time, forming a double image of the left and right images.

When the audience wears special polarizing glasses, the polarization axis of the left and right polarizers is perpendicular to each other and consistent with the polarization axis in front of the projection lens; As a result, the left eye of the audience can only see the left image and the right eye can only see the right image, and the left and right images are superimposed on the retina through the binocular convergence function, and the three-dimensional visual effect is generated by the brain nerves. It shows a coherent three-dimensional picture, so that the audience can feel that the scenery is rushing to the face, or entering the deep recess of the screen, which can produce a strong sense of "immersion".

The most popular 3D film now is "Avatar", and the others are:

BioWarrior 1 2 3 series.

The full 3D animated movie of the United States, the classic of the classic beam wheel, the picture is extremely gorgeous and colorful.

Star Catastrophe is an American 3D animated movie that can be compared to Final Fantasy, but the overall effect is a little more blunt than Final Fantasy, but it's not a great animated movie either.

Gaina" is a work that has created a milestone in European 3D animated films, and is the first fully 3D feature-length animation in Europe. Its picture is more beautiful than "Final Fantasy 7 Advent Son", but it was made in France, and the character design I think is a little awkward.

Dinosaurs 3D graphics are very good, taking you closer to a vivid and beautiful primitive world.
