What is the difference between 3D and 2D?

The terms "three-dimensional" (3D or 3-D) and "two-dimensional" (2D or 2-D) are most commonly used with a reference to photo and other graphic image technology such as animation and computer graphics. The difference between 3D and 2D images is that 3D images add depth perception. On the other hand, 2D image has only height and width. The term "three -dimensional" is also sometimes used to describe a physical item such as sculpture or mobile phone, which can be described as three -dimensional art compared to two -dimensional painting. Early 3D technology imitated this process with a double camera or dual lens. Modern computer technology can easily create realistic effects in 3D and 2D. This has an effect on the flattening of the image, reducing or eliminating the effect of depth. Natural vision creates this effect because the eyes are slightly distinguished, allowing the brain to process two different views of the same image. During the end of the 19th century, photographers tried toTo correct this problem with double crank and movement cameras that have been designed to work in tandem. Bringing these "stereoscopic" images through special viewers simulated the effect of seeing a three -dimensional image.

3D and 2D conditions for the first time came into popular use due to the film industry. During the 1950s, Hollywood filmmakers with 3D movies experimented as a marketing trick. These films were made with a variation on the stereoscopic settings of dual cameras. They were expensive to produce and demanded that viewers wear special glasses to experience a 3D effect. Only a few of these films have become a permanent classic, most in the genre of horror/tension, such as House of Wax , Creation from Black Lagoon and Alfred Hitchcock's Dial for Murder

The second wave of 3D films in the 80s had similar results. EarliestMeanwhile, video games also had 2D graphics, but in the 80s and 90s. By the 21st century, computer -generated images (CGI) could create 3D and 2D effects for large and small screens. In 2009, James Cameron Avatar promoted a new wave of Cinematic 3D a combination of top CGI and digital films technology. Soon many of Hollywood films with a large budget followed suits.

In real life, there is another fundamental difference between 3D and 2D visions. The three -dimensional vision contributes to the perception of depth or ability to estimate the distance of the object. This fact was Funny pointed out the TV series Sci -Fi futurama , because one of the main characters of the show Leela has only one eye. Although he is a pilot of interstellar spacecraft, Lela often complains that he does not have a perception of depth. It is irony that Andre de Toth, director of the famous 3D movie House of Wax , also had only one eye and hedid not see in 3D.
