Depth , from Latin go deep, is the deep quality (something that is deeper than regular, that is extended throughout or that penetrates a lot). The depth also refers to the deep part of something (such as being, for example, a pool).
Let's look at its use in some example sentences: “Be careful: this pool has a depth of almost three meters”, "He went deep into the forest and never came back", "As it descended, the cave seemed to have a growing depth".
The depth allows to name the dimension of the bodies perpendicular to a given surface. On flat surfaces, depth is only an effect that is achieved according to various techniques and to the use of the proportions: "The artist achieved a sense of depth with faint lines and careful use of light", “The depth that the street artist has managed to give his work is truly impressive”.
In a metaphorical or symbolic sense, the depth is the penetration or depth of ideas or thoughts. The deep, therefore, turns out opposite to the superficial . In other words, it is a concept that implies reaching the essence of an issue and not remaining in the apparent: “It is a very deep book, through which the author strips his soul and delivers his most private confessions”, "In an effort to demonstrate their depth, many celebrities ignore the questions of their interviewers and make very forced statements".
It should be noted that the depth of an idea or, in broad strokes, of a person is relative to the appreciation of another individual, so it is not a question of characteristic rigid or static personality. For many, being attracted to fashion and aesthetic trends is a superficial attitude, which pays attention to the material and neglects interior development; In the same way, there is a generalized idea that qualifies those who are passionate about reading as profound.
However, we find it especially difficult for human beings observe our own life from an external perspective, judge ourselves as others do, accept and understand our defects and our weaknesses; therefore, it cannot be pretended that a person who in the eyes of another is superficial, recognizes it, or that someone considered deep and very educated has that same view of himself.
In the graphics generated by computer, the emergence of depth represented a great revolution, both in the film and play industry, although it has also had an impact on science. In this case, however, it is necessary to distinguish between images constructed from points located in a three-dimensional world and stereoscopic projections, that is, that allow viewers to perceive the depth of the scenarios, as if the screen were a window to another reality.
To the confusion of many consumers, both technology They are abbreviated in the same way: 3D. However, stereoscopy is a very old practice, dating from the mid-nineteenth century and consisting of showing each eye a different image, the same scene seen from two slightly different angles, so that the brain is able to recreate the depth Without much effort.
Three-dimensional objects created by computer can be displayed in screens two-dimensional, as in most cases, for two decades: tens of millions of people have been exploring worlds for years whose depth they must understand through their own experience, since conventional monitors do not offer any kind of help to the brain for said calculation.
A deep wound Finally, it is the one that crosses the skin and can enter the body until you reach the muscles and bones: "The depth of the wound forced doctors to operate urgently".
