Distance Fog
Distance fog is a technique used in 3D computer graphics to enhance the perception of distance by shading distant objects differently. Because many of the shapes in graphical environments are relatively simple, and complex shadows are difficult to render, many graphics engines employ a " fog" gradient so objects further from the camera are progressively more obscured by haze and by aerial perspective. This technique simulates the effect of light scattering, which causes more distant objects to appear lower in contrast, especially in outdoor environments. Visibility in a natural haze declines exponentially, not linearly, with distance due to scattering. The colour of the light being scattered into the viewing path affects the colour of the haze; blue under blue skies, reddish near sunset, as with alpenglow. These more subtle details are represented in some graphics. "Fogging" is another use of distance fog in mid-to-late 1990s games, when processing power was not enough ...

Fogging (photography)
Fogging in photography is the deterioration in the quality of the image or the negative caused either by extraneous light, other electromagnetic radiation, radioactivity or the effects of a processing chemical. It is seen either as deposition of silver or dyes across all or part of the image unrelated to the original exposure. It can be confused with chemical staining that can be produced from poorly compounded developer, contamination of processing baths or poor washing after processing. Light Light fogging is where unintended light reaches the photographic material prior to processing is seen as dark areas in the negative which tend to occur over the full width of the film including the margins. This can occur to the film in the camera because of a defect in the manufacture or use of the camera and is seen as dark areas in the negative which tend to occur over the full width of the film including the margins. In 35mm film shadowing from the sprocket holes may be seen on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fogging (censorship)
Fogging, also known as blurring, is used for censorship or privacy. A visual area of a picture or movie is blurred to obscure it from sight. This form of censorship is used for sexually related images/scenes, hiding genitals, pubic hair, or sexual penetration of any sort. Pixelization Pixelization (British English, pixelisation) or mosaic processing is any technique used in editing images or video, whereby an image is blurred by displaying part or all of it at a markedly lower resolution. It is primarily used for censorship ... is a form of fogging. In Japan, where it is called ''bokashi'', fogging is employed on most films aired on public television that feature adult content of any kind. This form of editing also appears in television programs where an individual's face may not be shown due to legal or privacy concerns. As it does not contrast with the surrounding image very much, it is arguably preferable over most other forms of censorship. However, unlike other forms o ...

Anti-fog
Anti-fog agents, also known as anti-fogging agents and treatments, are chemicals that prevent the condensation of water in the form of small droplets on a surface which resemble fog. Anti-fog treatments were first developed by NASA during Project Gemini, and are now often used on transparent glass or plastic surfaces used in optical applications, such as the lenses and mirrors found in glasses, goggles, camera lenses, and binoculars. The treatments work by minimizing surface tension, resulting in a non-scattering film of water instead of single droplets. This works by altering the degree of wetting. Anti-fog treatments usually work either by application of a surfactant film, or by creating a hydrophilic surface. Development Anti-fog agents were initially developed by NASA during the Project Gemini, for use on helmet visors. During Gemini 9A, in June 1966, Astronaut Eugene A. Cernan tested NASA's first space suit, and discovered during the space walk that his helmet visor fogg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fogging (assertiveness)
Assertiveness is the quality of being self-assured and confident without being aggressive to defend a right point of view or a relevant statement. In the field of psychology and psychotherapy, it is a skill that can be learned and a mode of communication. ''Dorland's Medical Dictionary'' defines assertiveness as: :"a form of behavior characterized by a confident declaration or affirmation of a statement without need of proof; this affirms the person's rights or point of view without either aggressively threatening the rights of another (assuming a position of dominance) or submissively permitting another to ignore or deny one's rights or point of view." Assertiveness is a communication skill that can be taught and the skills of assertive communication effectively learned. Assertiveness is a method of critical thinking, where an individual speaks up in defense of their views or in light of erroneous information. Assertive people are able to be outspoken and analyze information and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Cigarette
An electronic cigarette is an electronic device that simulates tobacco smoking. It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor. As such, using an e-cigarette is often called "vaping". The atomizer is a heating element that vaporizes a liquid solution called e-liquid, which quickly cools into an aerosol of tiny droplets, vapor and air. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most kinds are reusable. The vapor mainly comprises propylene glycol and/or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on several things including user behavior. Vaping is likely much less harmful than smoking. E-cigarette vapor contains fewer toxins than cigarette smoke. It contains traces of harmful substances not found in cigarette smoke. Nicotine is highly addictive. Users ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fogging (insect Control)
Fogging is a technique used for killing insects that involves using a fine pesticide spray (aerosol) which is directed by a blower. In some cases, a hot vapour may be used to carry the spray and keep it airborne for longer. Fast-acting pesticides like pyrethroids are typically used. This is widely used for sampling or studying insects in the canopy of tall forests which cannot be effectively reached. The floor below the trees are lined with plastic sheets and the fog causes insects to fall in the rain. These are collected for later study in the laboratory. Fogging is also used for controlling insects in closed spaces like greenhouse A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic condit ...s, homes and basements.

Fog Computing
Fog computing or fog networking, also known as fogging, is an architecture that uses edge devices to carry out a substantial amount of computation ( edge computing), storage, and communication locally and routed over the Internet backbone. Concept In 2011, the need to extend cloud computing with fog computing emerged, in order to cope with huge number of IoT devices and big data volumes for real-time low-latency applications. Fog computing, also called edge computing, is intended for distributed computing where numerous "peripheral" devices connect to a cloud. The word "fog" refers to its cloud-like properties, but closer to the "ground", i.e. IoT devices. Many of these devices will generate voluminous raw data (e.g., from sensors), and rather than forward all this data to cloud-based servers to be processed, the idea behind fog computing is to do as much processing as possible using computing units co-located with the data-generating devices, so that processed rather than raw d ...
