illumination , from Latin illuminatio, is the action and effect of lighting . This verb refers to light or give birth and always requires a direct object, something or someone to give clarity to. It is known as lighting, therefore, at set of lights that is installed in a certain place with the intention of affecting it visually . For example: "The play was not bad, but the lighting was so poor that you could barely see the actors", “Last night I saw a show from a fountain of Water with amazing lighting effects ”.

The lighting is carried out through various elements and artifacts, as incandescent lamps (also known as light bulbs, bulbs or bulbs), fluorescent lamps or halogen lamps . The latter are especially used in offices, since they consume less energy than conventional ones, and are characterized by emitting a very intense light and little considered with wrinkles and other facial defects that people usually try to hide.

The lighting concept also allows reference to the mystical, experimental or rational inner clarification . Enlightenment, in this sense, implies the acquisition of a new understanding that gives a feeling of fullness.

The intellectual lighting , on the other hand, is to put something in Sure, to get into a subject until it reaches the bottom of it. In this case, there is no mystical aspect, but rational or experimental.

The spiritual enlightenment On the other hand, it is an experience linked to the divine. The subject who attains enlightenment feels the presence of God and finds a new meaning to existence through the peace and the love .

He buddhism consider that a Buddha It is a fully enlightened being that has developed positive qualities and eradicated the negative of its existence. There are different currents within this philosophical and religious doctrine: some consider that any human being can reach enlightenment and become a Buddha, while others argue that only some chosen can access that step.

The lighting effects and the 3d

In the last decade, the role of lighting in video games has gone from being important to essential. It should be mentioned that in the 80s and 90s, mainly in two-dimensional titles, but also in the first experiments with the third dimension, light was not realistically represented, given the technical limitations of computers and consoles. In fact, during the first era of the play industry, the characters and stages lacked any kind of lighting.

As the technology allowed to increase the detail in the graphic elements, the position of the light began to hint by means of static shading of the drawings; in other words, even if there was a lamp somewhere on one level, it did not really affect the characters that passed by her, which left evidence that it was not reality.

Among the first experiments that many developers performed to improve these situations, is the use of a translucent layer of the color of the light that is wanted to represent, that perches on other elements to give the sensation of being illuminating them. Another way to simulate lighting is to change a character's color palette for a lighter or darker one, depending on its proximity or distance from a light source. This last method was widely used in the first litter of three-dimensional games, and was especially convincing in racing titles, since high speed makes it very difficult to analyze the details.

Today, different lighting techniques are used, each with a different purpose, and in the best cases it is possible to create scenes very realistic. While no one has managed to perfectly emulate the true behavior of light, very few people have the technical knowledge to notice it; Moreover, if the artistic direction of the game is very good, it is likely that even experts forget that what they see It's not real.
