⭐ Core Definition: Vector monitor

A vector monitor, vector display, or calligraphic display is a display device used for computer graphics up through the 1970s. It is a type of CRT, similar to that of an early oscilloscope. In a vector display, the image is composed of drawn lines rather than a grid of glowing pixels as in raster graphics. The electron beam follows an arbitrary path, tracing the connected sloped lines rather than following the same horizontal raster path for all images. The beam skips over dark areas of the image without visiting their points.

Some refresh vector displays use a normal phosphor that fades rapidly and needs constant refreshing 30-40 times per second to show a stable image. These displays, such as the Imlac PDS-1, require some local refresh memory to hold the vector endpoint data. Other storage tube displays, such as the popular Tektronix 4010, use a special phosphor that continues glowing for many minutes. Storage displays do not require any local memory. In the 1970s, both types of vector displays were much more affordable than bitmap raster graphics displays when megapixel computer memory was still very expensive. Today, raster displays have replaced nearly all uses of vector displays.

👉 Vector monitor in the context of Calligraphic projection

Calligraphic projection (also known as vector graphics) is a system for displaying or projecting an image composed of a beam of light or electrons directly tracing the image, as opposed to sweeping in raster order over the entire display surface, as in a standard pixel-based display. Calligraphic projection is presently often used for laser lighting displays, whereby one or more laser beams draws an image on a screen by reflecting the laser beam from one or more mirrors attached to a deflecting mechanism.

Analog oscilloscopes have customarily employed this kind of vector graphics, as did a number of CRT-based vector monitor computer graphics terminals in the 1970s and 1980s, such as the Tektronix 4014 and the Evans & Sutherland Picture System.

Vector monitor in the context of Golden age of arcade video games

The golden age of arcade video games was the period of rapid growth, technological development, and cultural influence of arcade video games from the late 1970s to the early 1980s. The release of Space Invaders in 1978 led to a wave of shoot-'em-up games such as Galaxian and the vector graphics-based Asteroids in 1979, made possible by new computing technology that had greater power and lower costs. Arcade video games switched from black-and-white to color, with titles such as Frogger and Centipede taking advantage of the visual opportunities of bright palettes.

Video game arcades became a part of popular culture and a primary channel for new games. Video game genres were still being established, but included space-themed shooter games such as Defender and Galaga, maze chase games that followed the design established by Pac-Man, driving and racing games which more frequently used 3D perspectives such as Turbo and Pole Position, character action games such as Pac-Man and Frogger, and the beginning of what would later be called platform games touched off by Donkey Kong. Games began starring named player characters, such as Pac-Man, Mario, and Q*bert, and some of these characters crossed over into other media including songs, cartoons, and movies. The 1982 film Tron was closely tied to an arcade game of the same name.

Vector monitor in the context of Vectrex

The Vectrex is a vector display-based home video game console, the only one ever designed and released for the home market, that was developed by Smith Engineering and manufactured and sold by General Consumer Electronics. It was first released for the North American market in October 1982 and then Europe and Japan in 1983. Originally produced by General Consumer Electronics, it was later licensed to Milton Bradley after they acquired the company. Bandai released the system in Japan under the name 光速船, meaning Lightspeed.

The Vectrex, in contrast to other video game systems at the time, did not need to be hooked up to a television set; it had an integrated (vertically oriented) monochrome CRT monitor. A detachable wired control pad could be folded into the lower base of the console. Games came with translucent color overlays to place over the screen. Optional peripherals include a pair of 3D goggles known as the "3D Imager" and a light pen for drawing directly on the screen. The Asteroids-inspired Mine Storm was built into the system.
