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.
The gated system uses a pulsed light source and a synchronized camera that enable long ranges (250m) and high performance in rain and snow. Near Infrared wavelength is 0.75–1.4 µm is smaller and can pass between the typical fog particles. Fog particles sizes are typically 10 to 15 microns and ranges is sizes from 1 to 100 microns. [6]
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 .
The forward-facing camera used for the PlaneView EVS on a Gulfstream G450. An enhanced flight vision system (EFVS, sometimes EVS) is an airborne system which provides an image of the scene and displays it to the pilot, in order to provide an image in which the scene and objects in it can be better detected.

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).
iSight is a brand name used by Apple Inc. to refer to webcams on various devices. The name was originally used for the external iSight webcam, which retailed for US$149, connected to a computer via a FireWire cable, and came with a set of mounts to place it atop any then current Apple display, laptop computer, all-in-one desktop computer, or round surface.
