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 ...
At the top right corner is a monocular for assisting the alignment of the two heads. Free-space optical communication ( FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. "Free space" means air, outer space, vacuum, or something similar.
The nanometre ( SI symbol: nm) is a unit of length in the metric system equal to 10−9 metres ( 1 1 000 000 000 m = 0.000 000 001 m ). To help compare different orders of magnitude, this section lists lengths between 10 −9 and 10 −8 m (1 nm and 10 nm). 1 nm – diameter of a carbon nanotube.

In computer graphics, level of detail ( LOD) refers to the complexity of a 3D model representation. [1] [2] [3] LOD can be decreased as the model moves away from the viewer or according to other metrics such as object importance, viewpoint-relative speed or position. LOD techniques increase the efficiency of rendering by decreasing the workload ...
Draw distance. The influence of different draw distances (Higher distances show more area.) In computer graphics, draw distance ( render distance or view distance) is the maximum distance of objects in a three-dimensional scene that are drawn by the rendering engine. Polygons that lie beyond the draw distance will not be drawn to the screen.
Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. [1] [2] It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces. However acoustic tweezers are generally small scale devices which operate in a fluid medium and are ...
The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.
