Ringlets are the curls that form in the hair.
They never go out of style . Some people are fascinated by them and try to create them, although others lament their natural existence and try to eliminate them when they spread throughout their hair. We are talking about loops , those curls or curls that form in the hair and give a very particular appearance.
For example: “When I was little, my head was full of curls,” “The model surprised by changing her look and abandoning the curls,” “A curl fell right between her eyes, giving her a very nice appearance.”
The loop concept, however, can also be used in other areas. Different elements that have a curly appearance , similar to a helicoid , can be mentioned as a loop. It is even possible to refer to loops that are named for their operation and not for their appearance .
Loop in programming
In the field of programming , a loop is a structure that allows the repetition of statements on many occasions. When the programmer stipulates a certain condition and said condition is met (that is, it turns out to be true), the execution of the loop occurs, which will only stop when the condition is no longer met.
What is the advantage of including a loop in programming? This type of structure allows an action to be repeated over and over again, without the need to copy identical code. This way the final code is cleaner and can be modified more easily.
That which has a curly appearance can be called a loop.
Its importance for simulation
The loop is not only convenient in certain cases, but is mandatory in others. Nowadays, thanks to advances in technology , video games often include various types of particles, which are small graphic objects used to simulate water, fire, sand, earth and magic effects, among other things that were previously animated by hand. and they could not interact dynamically with the rest of the objects.
In most cases, especially in products that pursue realism, several hundred particles or more are needed moving and reacting to events in their environment individually; If a loop were not used to control them, the same code would have to be repeated for each of them, something that no one in their right mind would do. The example of particles, although only the most knowledgeable programmers delve into its territory for the creation of special effects and the simulation of elements, is very suitable to understand the usefulness and potential complexity of a loop.
Even if a scene has thousands of water particles, for example, each one with its own life cycle, experiencing different things and adopting different aspects and sizes, we must not forget that they all start from the same class, from the same type of object, for which they share properties and functions. In other words, if they are all instances of a class called "water", then they will have the same possibilities and the same "capabilities", their behavior will be based on the same code, even if the results are different each time.
Loop Utility
A loop in which a large group of particles is controlled offers each one the same functions, the same lines of code.
However, depending on the state in which each one is, they will travel one path or another within the loop, and that is why it is likely that some will evaporate, others will soak a character's clothing, and others will, for example, scatter. on the grass. This shows that although a loop can do the same thing on each turn, within it there can be direct or indirect conditions that multiply the possibilities.
For telecommunications , meanwhile, a subscriber loop (also known as a local loop ) is the section of a cable run that connects the telephone exchange with the home of the person who uses the service.
