LCD (Liquid
Crystal Display):
A type of display used in digital watches and many
portable computers. LCD displays utilize two sheets of polarizing material with
a liquid crystal solution between them. An electric current passed through the
liquid causes the crystals to align so that light cannot pass through them.
Each crystal behaves like a shutter, either allowing light to pass through it
blocking the light. The benefits of DVI LCDs, in addition
to those of DVI CRTs, are:
Light map:
Specific texture which simulates lighting effects
according to the origin of the light source.
Lighting:
A mathematical formula to approximate the physical
effect of various sources of light striking objects. Typical lighting models
use light sources, the object's position & orientation and surface type.
