In volumetric lighting, the light cone emitted by a light source is modeled as a transparent object and considered as a container of a "volume". As a result, light has the capability to give the effect of passing through an actual three-dimensional aerosol (e.g. fog, dust, smoke, or steam) that is inside its volume, just like in the real world.
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 are progressively more obscured by haze and by aerial ...
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in video telephony , live streaming and social media , and security . Webcams can be built-in computer hardware or peripheral devices , and are commonly connected to a device using USB or wireless protocol .
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 mid air.

In 2010 Microsoft brought the Kinect to the market, a consumer product that used structured light in the infrared spectrum to generate a 3D mesh from its camera. While the intent was to facilitate and innovate in user input and gameplay, it was very quickly adapted as a generic capture device for 3D data in the volumetric capture community.
They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect is 3 to 12 μm and differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm).

In filmmaking and video game development, it refers to recording actions of human actors, and using that information to animate digital character models in 2-D or 3-D computer animation. [ 5 ] [ 6 ] [ 7 ] When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. [ 8 ]
