In order to look solid, a polygon must be “shaded” with color.
This happens when the polygon is rendered. There are several ways to shade a polygon. These have varying degrees of realism and cost. A polygon’s shading depends on its surface properties, the properties and location of the lights with which it is lit. The shading methods (types) available on PictureMaker are constant, flat, Gouraud, and Phong. The latter two are “smooth” shading types.
Industry:Software
A mechanism for controlling the movement of magnetic tape, commonly used to move magnetic tape past a read head or write head, or to allow automatic rewinding.
Industry:Software
A rectangular subregion of the video image that is displayed using local decode. See Local Decode.
Industry:Software
The number of bits of color information per pixel. A system using eight bits per pixel can display 256 (28) colors. A system using 16 bits per pixel can display 65,536 (216) colors. A system using 24 bits per pixel can display over 16.7 million colors. Twenty-four-bit color is often called true color because the human eye can distinguish among approximately six million different colors, or fewer than are available in a 24-bit color system.
Industry:Software
The movement of the electron beam from the right-hand edge of the display to the left-hand edge or from bottom to top.
Retrace occurs during the blanking time. See Horizontal Retrace and Vertical Retrace.
Industry:Software
A half-resolution input signal used by MPEG-1. See Standard Input Format. This is also known as “Source Input Format” and “Standard Interchange Format.”
Industry:Software
The time sequence of the bits (DVB-S) is predefined by convolutional coding and, like the state diagram of a finite automaton, is represented as a trellis diagram.
Industry:Software
The magnetizable particle used in the manufacture of magnetic tape.
Industry:Software
a) Coding where analog input signal is represented by a given number of fixed-width digital samples per second.
Often used for the coding employed in the telephone network. b) A technical term for an analog source waveform, for example, audio or video signals, expressed as periodic, numerical samples. PCM is an uncompressed digital signal. c) This is a form of the digital audio signal used for both CD and laserdisc. It is a serial data stream that is coded for transmission or recording. PCM is also used for many other types of serial data communications.
Industry:Software
A type of key border effect. A shadow key with a character generator appears as if the letters have been raised off the surface slightly and a light is shining from the upper left; a shadow appears to the right and bottom of the characters.
