In computer graphics, antialiasing is a software technique for diminishing jaggies – stairstep-like lines that should be smooth. Jaggies occur because the output device, the monitor or printer, doesn’t have a high enough resolution to represent a smooth line. Antialiasing reduces the prominence of jaggies by surrounding the stairsteps with intermediate shades of gray (for gray-scaling devices) or color (for color devices). Although this reduces the jagged appearance of the lines, it also makes them fuzzier.
Another method for reducing jaggies is called smoothing, in which the printer changes the size and horizontal alignment of dotsto make curves smoother.
Antialiasing is sometimes called oversampling.
Slang term used to describe the merging of anticipation and disappointment.

A device that controls the amount of light admitted through an opening. In photography and digital photography, aperture is the unit of measurement that defines the size of the opening in the lens that can be adjusted to control the amount of light reaching the film or digital sensor.

In satellite communications, most satellites orbit the earth in elliptical patterns with the earth not in the exact center of the orbital pattern. When a satellite is at its furthest point from the earth, it is at the apogee of the orbit. When a satellite is at its closest point to the earth, it is […]
