Fog display. A fog display, fog screen, vapor screen or vapor display is a system that uses haze machines or water vapor to create a semi-transparent wall, or "curtain" of suspended particles which trapped in a thin sheet ( laminar flow) of air and are illuminated by a projector, [1] in order to produce a display whose images seem to float in ...
Fog collection is the harvesting of water from fog using large pieces of vertical mesh netting to induce the fog-droplets to flow down towards a trough below. The setup is known as a fog fence, fog collector or fog net. Through condensation, atmospheric water vapour from the air condenses on cold surfaces into droplets of liquid water known as ...
Heliodisplay. The Heliodisplay is an air-based display using principally air that is already present in the operating environment (room or space). The system developed by IO2 Technology in 2001 uses a projection unit focused onto multiple layers of air and dry micron-size atomized particles in mid-air, resulting in a two-dimensional display ...
A marine radar with automatic radar plotting aid ( ARPA) capability can create tracks using radar contacts. [ 1] The system can calculate the tracked object's course, speed and closest point of approach [ 2] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass. Development of ARPA started after 1956, when the ...
A liquid-crystal display ( LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly [ 1] but instead use a backlight or reflector to produce images in color or monochrome.
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. [ 6] Many of these devices will generate voluminous raw data (e.g., from sensors), and rather than forward all ...
Volumetric display. A volumetric display device is a display device that forms a visual representation of an object in three physical dimensions, as opposed to the planar image of traditional screens that simulate depth through a number of different visual effects. One definition offered by pioneers in the field is that volumetric displays ...
Distance fog is a technique used in 3D computer graphics to enhance the perception of distance by shading distant objects differently. [1] 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 ...
