What is 3D movie? Introduction to 3D movie

1. 3D movies are "three-dimensional movies". They use a stereoscope visual display system to recreate the picture to display the left and right eye plane projection images in three dimensions, giving the audience an unrealistic three-dimensional depth to the images. .

2. Technically, two cameras are usually used to shoot images simultaneously to obtain a three-dimensional sense of the left and right sides of the subject. When watching, the viewer's visual cortex automatically combines the images into a single three-dimensional image. Modern computer technology has made it possible to use CGI computer special effects to produce three-dimensional movies instead of traditional dual-camera shooting. You need to wear suitable 3D glasses when viewing.

3. The lens is actually a pair of polarizers with perpendicular transmission directions. The principle is that usually only when looking at objects with two glasses can a three-dimensional effect be produced. If two lenses are used, like the human eye, the image of the movie scene can be captured from two different directions at the same time and made into a positive film.

4. During the projection, two projectors use two polarized lights with vibration directions perpendicular to each other to overlap and project onto the screen. Human eyes watch through the above-mentioned polarized glasses, and each eye can only see A corresponding independent image. It will produce a three-dimensional feeling just like when viewed directly.
