Bi/Tri-Linear Filtering

by Dummy Admin

A simple form of texture filtering, point sampling, could be used to scale textures prior to their being mapped onto surfaces in a 3D scene. This technique could easily introduce errors by taking a …

There are parts of the CRT that control the production, flow, acceleration and direction of the tube’s electron beam but leave its shape unaltered. As the electrons accelerate towards the screen, they tend to …

Aperture Grille

by Dummy Admin

Before the three-gun, shadow mask CRT was firmly established as a standard for producing colour CRTs, several other novel systems were developed. One of these was the PDF (Post Deflection Focusing) Chromatron developed at …

Antialiasing

by Dummy Admin

Antialiasing, as the name suggests, is a technique used to combat an effect known as aliasing. When a line is drawn on a piece of paper, its edges appear smooth regardless of the line’s …

Anode

by Dummy Admin

The control grid regulates the number of electrons which are allowed to leave the gun of a CRT by using a negative voltage to repel the electrons. Once free of the control grid’s influence, …

Anistropic Filtering

by Dummy Admin

Anisotropic means “non-uniform shape” and it is because this filtering technique works on non-uniform, or uneven, shaped areas that it is more powerful, and takes much more processing power, than Point Sampling, bi-linear or …

Alpha-Blending

by Dummy Admin

Alpha-blending is a technique which can be used when computer graphics are laid on top of each other and one or more of the objects contain a transparent, or semi-transparent, portion. It ensures that …

ALiS

by Dummy Admin

Developed by Fujitsu as an improvement to the Three Electrode Surface Discharge method of driving a PDP, which it invented in 1984, ALiS (Alternate Lighting of Surfaces) displays are not made up of enclosed …

Active matrix (AM/TFT)

by Dummy Admin

In Super Twisted Nematic LCs, we see how multiplexed addressing allows an array of pixels to be controlled in such a way as to allow a high definition display to be built with liquid …

Display Glossary
