How was the 3D movie made?

When shooting 3D movies, two cameras were used to imitate human eyes. There are some sayings in the industry, such as "bug eye", "human eye" and "giant eye". If you want to take a close-up shot, the two cameras should be as close as the eyes of a fly. Generally speaking, the distance between two cameras is similar to that of human eyes. If you want to take a long view, two cameras should be as wide as a giant's eyes.

According to the shooting distance, there is a formula to calculate how far the distance between the two cameras should be. But it is not enough to rely solely on formulas, but mainly on experience. Sometimes it is possible to put two cameras vertically or obliquely, and then use a mirror to complete the shooting.

Application of 3D technology:

The application of 3D technology is very extensive, including the development and production of cultural and artistic products for visual expression, such as film and television animation, animation and games, the design and production of physical products such as automobiles, airplanes, household appliances and furniture, and the simulation and simulation of the virtual reality of human interaction with the environment. Specifically, it includes: 3D software industry, 3D hardware industry, digital entertainment industry, manufacturing industry, construction industry, virtual reality, geographic information GIS, 3D Internet and so on.
