A television-like scanned-display system has been successfully implemented on a Honeywell DDP-224 computer installation. [...] Key Method The scanned image is stored in the core memory of the computer, and software scan conversion is used to convert the rectangular coordinates of a point to the appropriate word and bit in an output display array in core storage. Results thus far indicate that flicker-free displays of large amounts of data are possible with reasonably fast graphical interaction. A scanned image…Expand
Scan conversion algorithms for a cell organized raster display
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.

VISION II: a dynamic raster-scan display
This paper describes a digital video display system architecture with dynamic graphics capabilities and the hardware design and implementation derives from the author's thesis work at the University of Illinois. Expand
A cell organized raster display for line drawings
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
A scan conversion algorithm with reduced storage requirements
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.

Digital video display systems and dynamic graphics
It is shown how dynamic graphics capabilities can be provided if systems adhere to one or the other of two possible architectures, and examples of such systems are presented. Expand
Computer generation of colored planar patterns on TV-like rasters
Two different and complete schemes of colored pattern generation (CRPG) are given as examples and solutions are derived from using known algorithms embedded in a frame especially designed to meet the constraints. Expand
Computer-generated spectrogram displays for on-line speech research
A program to generate and display spectrograms on a computer-controlled scanned-display television monitor is described. The program features computation of power spectra for selected time segmentsExpand
Architectures and algorithms for parallel updates of raster scan displays
The symmetric square organization which allows the access of square regions of the display is advocated which is shown to be indeed better than the scan-line organization. Expand
Computer-Generated Spectrogram Displays n-Line Speech Research
Spectrograms suffer from intensity and spatial resolution limitations relative to conventional spectrograms, but their rapid generation and flicker-free display makes their use appropriate in a man-computer interactive environment to complement aural evaluation of digitally synthesized or processed speech signals. Expand
An interactive system for page layout design
A prototype interactive page layout system is described in which textual and pictorial information can be manipulated under computer control on a scanned color display, suitable for designing both the individual advertisements and complete pages of directories or newspapers. Expand


Scientific Applications: BRAD: the brookhaven raster display
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 upExpand

A computer technique for producing animated movies
This paper describes a computer technique used for the production of animated diagram movies that involves the basic steps of coding and checkout, production computer run, and optical printing from the master film thus produced. Expand
Laboratory computers: Their capabilities and how to make them work for you
An introduction to laboratory computer operating systems to serve as a starting point for someone intending to create his own system to show how a specific system may be developed by modifying and incorporating features of existing systems and by modifying standard Programs supplied by computer manufacturers.
