The representation of perspective requires calculations of proportions.
Perspective is the art that is dedicated to the representation of three-dimensional objects on a two-dimensional (flat) surface with the intention of recreating the relative position and depth of said objects . The purpose of perspective is, therefore, to reproduce the shape and arrangement with which objects appear in view.
Both this technique and the work or representation that is executed through this art are known as perspective. For example: “In this painting we see the perspective of a mountain from its base” , “The drawing teacher congratulated me on the work, although he advised me to pay special attention to the perspective” .
How perspective is represented
A common way to calculate proportions and make a correct representation of perspective is to use a pencil as a ruler , and it consists of the following steps: choose the object that you want to use as a parameter for the drawing and then, with your arm outstretched, , the pencil is taken with the tip facing up and the tip is aligned with the top of the object, while the finger marks the bottom. This technique helps calculate the proportions of various objects to transfer them to paper.
By using 3D design programs, artists don't have to worry about calculating perspective; However, through the ingenious use of the camera and its features, it is possible to create effects such as accentuating the size of certain elements , or falsely decreasing depth (making objects appear closer to each other in the z axis).
Perspective can be associated with point of view.
The point of view
By analogy to these notions, the point of view from which a given issue is considered is called perspective. In this sense, it is about the personal judgment or subjective vision of a subject: “From my perspective, the researcher's decision was the correct one,” “The president's perspective on the bilateral conflict is very different from that held by his ministers.” and advisors.”
Since living beings go through a complex and, in some cases, extensive development , it is understandable that our perspective is modified more than once throughout our lives. Based on our growth on a physical level, which causes us to see the world from different heights during the first years, the same situation will not have the same impact on a child, a teenager or an elderly person. Experiences provide us with elements that gradually alter certain concepts, which inevitably leads to a change in our way of understanding the environment and reacting to the events that surround us.
Many people fondly remember how much taller the Christmas tree seemed at age three , or how much bigger our childhood house looked; It is difficult for us to understand why our parents had fewer defects, what has caused the winters to no longer be as cold as before, or why we no longer have such a fluid relationship with a person who used to be very close to us. No one prepares us for such disappointments, and not everyone is prepared to tolerate them; However, looking at the world through different perspectives is natural and, no matter how hard it is for us to accept it, necessary .
The rest of the animals experience these changes as much as we do and, observing their lives, it is very easy to understand the urgent need to modify certain concepts in order to overcome the threats of the outside world . When a baby fox crosses paths with a boa, for example, it does not always have the cunning to move away quickly; However, this being that at first may seem funny and striking will become a clear threat when he learns the relevant lessons from his mother.
