UCLA-Computer Science Graphics Overview

I. Hardware

A. Imlac PDS-1

We have 2 PDS-1 graphics consoles each with 8K 16 bit words

of memory.

The display screens are mounted with the long axis vertical.

B. DEC 340

We have a DEC 340 Display Station with a light pen. Associ-

ated with the station are a Rand Tablet and a Lincoln Wand.

There is a display processor which drives the DEC 340 which

reads its instruction from the XDS Sigma 7 memory via dedi-

cated memory port.

II. Software

A. Imlacs

We have not as yet developed any software for the PDS-1.

We have used the Imlac provided text and graphics support

software to utilize the PDS-1's as alphameric and limited

graphics consoles (at 1200 baud).

These are used only with the SEX timesharing system.

B. DEC 340

We have over several years developed a package of Library

routines* which interface to FORTRAN programs for use with

the DEC 340 and its associated devices. This station is

used only with a stand alone system (RAD 75).

Several programs have been implemented using these facilities

among them are:

*SMOG (sub-program manager for On-Line Graphics).

MOSAIC is an experimental computer graphics program

which permits a user to manipulate the parameters of

a fairly complex polar co-ordinate equation. The ob-

ject is to explore the space of interesting images

which can be produced. Library facilities are provid-

ed so that the user can save interesting images. He

can also combine the images in many ways to form mo-

saic-like patterns. An Arriflex 16mm camera can be

driven through the use of this program, and we have

used the system to generate several films which serv-

ed as a basis for video-graphics experiments (TV video-
