UV noun explanation! ! ! ! ! !

There are two meanings, one is ultraviolet and the other is UV coordinate.

1, ultraviolet

UV (ultraviolet ray) refers to ultraviolet rays, which are divided into vacuum, low-frequency long wave, medium-frequency medium wave, high-frequency short wave and ultra-high frequency. Ultraviolet refers to the invisible radiation with the wavelength between 400 nm and 10 nm in the electromagnetic spectrum.

180 1 year, German physicist Ritter discovered that the outer layer of ultraviolet spectrum can make photographic film containing silver bromide sensitive, so he discovered the existence of ultraviolet rays. Ultraviolet rays can be used for disinfection. Excessive ultraviolet rays entering the human body can lead to skin cancer.

2.UV coordinates

Texture coordinates usually have two axes, u and v, so they are called UV coordinates. U represents the distribution in horizontal coordinates and v represents the distribution in vertical coordinates.

Extended data:

Ultraviolet surface sterilization devices are widely used in food, electronics, semiconductors, liquid crystal displays, plasma televisions, crystal oscillators, precision devices, chemical industry, medicine, health care, biology, beverages, agriculture and other fields. Ultraviolet light source irradiates the surface of food and materials, which has a rapid, efficient and pollution-free sterilization effect, thus maintaining the high quality of your products.

UV maps every point on an image to the surface of a model object accurately, and smoothly interpolates the image from point to point through software, which is called UV mapping.
