A multiconsole computer display system has been designed that provides very rich displays at low unit cost. Each BRAD (Brookhaven RAster Display) console can plot tens of thousands of points, or up to 4000 characters at 30 frames per second. After an initial display system investment of $50,000, each display, with teletype, cost less than $3,000. The technique employed is that of programmatically generating a binary image of the desired display in a computer. The image is written on a rotating… Expand

A Computer-Driven Full-Color Raster Scan Display System*
TLDR
The system to be described, which employs raster scan "painting" to provide rich, flicker-free pictures, is an IBM 1130 equipped with 8K of core, a disc, a card reader/punch, and a line printer. Expand
Three-dimensional computer display
A stereographic display terminal has been produced using the raster display (BRAD) recently developed at Brookhaven. The system uses a rotating refresh memory to feed standard television monitors. ToExpand
Scanned-display computer graphics
TLDR
A television-like scanned-display system has been successfully implemented on a Honeywell DDP-224 computer installation and results thus far indicate that flicker-free displays of large amounts of data are possible with reasonably fast graphical interaction. Expand
Microcoded Multiprogramming Display Control Unit
TLDR
A microcoded control unit was used to implement an experimental display system in the Los Gatos Laboratory of IBM’s Advanced Systems Development Division, which presents alphanumeric and graphic images on remote television terminals under computer control. Expand
A scan conversion algorithm with reduced storage requirements
TLDR
The scan conversion algorithm described here uses a linked list data structure to process the lines of the drawing in strips corresponding to groups of scan lines, and shows that storage requirements can be reduced by more than 80 percent while causing less than a 10 percent increase in execution time.

Scan conversion algorithms for a cell organized raster display
TLDR
Two fundamentally different scan conversion algorithms which have been developed to support this display are presented and show that the noninteractive algorithms can significantly reduce display file storage requirements at little cost in execution time over that of a conventional raster display. Expand
All Points Addressable Raster Display Memory
TLDR
This paper presents features of a customized dynamic RAM chip which can readily provide the necessary bandwidth and thus greatly simplify the design of very high performance APA raster scan displays and describes the second port for the video refresh, which makes the primary port available for update almost continuously. Expand
A cell organized raster display for line drawings
TLDR
A display is described which extends the capabilities of this organization to include general graphics, and the feasibility of such a display is shown by deriving the minimum number of patterns required in the read only memory of the character generator to synthesize an arbitrary line. Expand
An algorithm for programming electrostatic plotter type devices
TLDR
An algorithm for generating a display on electrostatic plotter type devices is described, designed to operate in a device independent computer plotting system and has worked very satisfactorily without imposing any restrictions on the users. Expand
