ACKNOWLEDGEMENT

The author wishes to express his appreciation to Mr.

William Thomas of the Electrical Engineering Computer Lab-

oratory for giving freely of his time and assistance through-

out the development of the work presented in this thesis.

I. INTRODUCTION

The aim of any computer graphics system is to maximize

the information transfer between the user and the computer,

preferably in an interactive way. As the applications for

computer graphics displays expand, characteristics of the

"optimum" system become more difficult to establish. "Optimum"

characteristics are a function of the problem to be solved,

i.e., the application. But the user may be further con-

strained" by budget limitations or equipment availability.

At the same time, the equipment manufacturer, although he

would like to offer the "optimum" system to each user, is

more often forced to produce standardized, versatile con-

figurations which will satisfy many requirements. Frequently

then, the user may find his graphics system lacking in one

or more attributes which would be desirable for his ap-

plication.

Attributes which are typical of most computer graphics

systems are [1]

:

(1) Generation of a steady, non-flickering display.

(2)' Generation of typical graphic elements (e.g.,

characters, lines, cursors, etc.).

(3) Performance of certain "routine" editing functions -

such as light pen tracking, erasing, scaling, ro-

tation, and translation.

The functions listed in attribute (3) can be accomplished

with hardware, software, or a combination of both hardware and

software. Those systems which utilize software for performing

the graphics editing function afford the user an opportunity

to "redesign" or modify the existing editor so that it more

closely resembles his "optimum" system. Such a system exists

in the Computer Laboratory at the Naval Postgraduate School.

The purpose of this thesis is threefold:

(1) To discuss design considerations taken

into account in redesigning GATED, the

graphics and text editor presently in

use at the Naval Postgraduate School;

(2) To present RADIK, a graphics and text

editor which more fully utilizes the

capabilities of existing hardware at

the Naval Postgraduate School; aid

(3) To propose implementation of RADIK at

the Naval Postgraduate School.

The thesis is divided into five parts. First, a brief

background of graphics research is presented. Secondly, this

thesis deals with the considerations taken into account when

designing RADIK. This includes a description of the hardware

installed in the computer laboratory of the Naval Postgraduate

School, along with the present editing system, GATED, and its

apparent shortcomings and deficiencies. In addition, the

second section contains a discussion of the XDS 9 300 FORTRAN

graphics package, a set of FORTRAN callable subroutines which

are used to create graphics data blocks and to transmit them

to the display computer.

The third part of the thesis presents RADIK, a software

graphics and text editor which can be used at the Naval Post-

graduate School. RADIK is compared to GATED and objectives

are stated. Results of the work on which this thesis is

based are then presented.

The fourth section summarizes the work and the fifth

proposes implementation of RADIK at the Naval Postgraduate

School. Program listings which were developed during the

design of RADIK are appended for further reference.

II. BACKGROUND

Once computer graphics systems had become a physical

reality, most of the technological research in the field was

devoted to providing improved hardware devices—devices which

could operate more reliably and with higher quality output

—

for printing and plotting information. Very little was done

to produce sophisticated hardware and software techniques to

better match the user to the computer. In the past few years,

however, the emphasis on visual displays has channeled much

research toward improving interaction between man and the

machine. In the early stages of this research, a great deal

of attention was given to the problem of standardizing pro-

gramming languages and developing economical, efficient com-

pilers to translate from programming languages to machine code.

Such work still continues. However, more emphasis is now

being placed on the development of graphics languages.

Much work has been done and many papers been written on

the design of a general purpose graphics language ([2], [3],

[4], [5]). However, the designer of a general purpose graphics

language is faced with a variety of users, each with his own

special applications. In order to satisfy the greatest number

of needs, the designer is forced to create a language which

will not satisfy some needs, and is, therefore, not general-

ized. One suggestion is to design a "super-language", which

would contain subsets for implementation by the various users.

10

The design of such a language, of course, would have to take

into account the fact that different users also have different

hardware. We are faced with the alternatives of a special

purpose graphics language for each user or, perhaps, several

"semi-general" purpose graphics languages, each of which

would accommodate many users. While the work presented in

this thesis was not in the area of language construction or

language design, it should be noted that RADIK provides the

interactive capabilities which most languages strive for,

while requiring the user to use only FORTRAN programming

and function switches to implement them.

III. CONSIDERATIONS IN DESIGNING A

GRAPHICS AND TEXT EDITOR

A. -EXISTING GRAPHICS HARDWARE AT THE NAVAL POSTGRADUATE SCHOOL

In order to understand the problems encountered in at-

tempting to design a graphics and text editor, one must be

aware of the philosophy, data structures, operating proce-

dures, and hardware configuration of the system in which it

is to reside. Reference [6], describes the Computer Laboratory

in detail. Present equipment at the Naval Postgraduate School

includes four computer systems: a medium size, general pur-

pose, digital computer system (XDS 9300), two small graphics

computer systems (AGT/10) , and one analog computer system

(CI 5000) . These systems may be used separately (referred

to as stand alone operation) or in combination with one or

more of the other systems. Figure 1 shows each system and

its communication links to the other computer systems. Note

that the analog and graphics systems each communicate with

the XDS 9300, but cannot communicate with each other except

via the XDS 9 300.

1. XDS 9300

The XDS 9 300 is the main computer in the laboratory.

It has a main (core) memory of 32K words and a magnetic drum

for secondary storage. System operation is controlled at the

operator's console and teletypewriter. Input to the XDS 9 300

is via card reader, teletypewriter, paper tape reader, or

magnetic tape drive while output may be sent to the line •

12

Figure 1. Electrical Engineering Computer Laboratory

13

printer, paper tape punch, teletypewriter, or magnetic tape

drive. The operations and organization of this system allow

real-time inputs via special input ports (some of these ports

are used to communicate with the CI 5000) . This real-time

capability allows the XDS 9 300 computer system to handle, in

addition to the obvious computational applications of a

digital computer system, many other applications. Such ap-

plications include the real-time monitoring, control, or

data reduction of concurrently operating scientific ex-

periments. Furthermore, these applications could also include

graphical display on the AGT/10 . The XDS 9300 may be pro-

grammed in its assembly language (META-SYMBOL) or in FORTRAN.

2. CI 5000

The CI 5000 computer system is an analog computer with

a full complement of digital logic. The analog portion is

primarily used for the solution of differential equations

with the digital logic allowing decision making and switching

to be performed. This system, in the stand-along mode, may

solve a large number of problems in simulation. The use of

the XDS 9 300 and the CI 5000 together allow hybrid computa-

tions. The major application of hybrid computation is in

the modeling of dynamic systems or optimization problems.

3. AGT/10

Each AGT/10 is a small general purpose digital compu-

ter with 8K of main (core) memory and magnetic disks for

secondary storage. Input is from a teletypewriter, paper

tape reader, lightpen, "joystick" type potentiometer, function

switches and variable control dial potentiometers. Output

14

appears on the cathode ray tube, paper tape punch, or tele-

typewriter. These I/O components, along with some special

graphics hardware, make them very effective graphics computers

Their limited storage and lack of a high level language

limits their stand-alone capability somewhat. However, when

the AGTs are used in conjunction with the XDS 9 300, a large

number of interactive, graphical problems may be handled.

B. FORTRAN GRAPHICS PACKAGE

The XDS 9 300 FORTRAN user presently has access to a

number of library subroutines for use in outputting graphics

information to the AGT/10 and GATED. The user is primarily

concerned with the areas of graphics initialization, output,

output with response, and input. Reference [6] contains

detailed explanations of the graphics subroutines as well as

examples of their use.

1. Graphics Initialization Subroutine--DGINIT

This routine must be called before any of the other

graphics subroutines may be called. This subroutine spec-

ifies a FORTRAN integer array as the graphics directory,

causes GATED to initialize its graphics directory in the

AGT/10, and deletes all graphics blocks. This, of course,

causes all graphics displays to be erased from the screen.

A typical call would be

CALL DGINIT (IDEV, IGDIR, NWDIR, IER)

IDEV is an integer variable which can assume the values 1 or

15

2, specifying the number of the AGT being used. IER is an

error flag used by all graphics subroutines. Specific values

of IER denote various error conditions which are listed in

[6] . IGDIR is the first word address of an integer array to

be used as the graphics directory. NWDIR is the dimension of

the graphics directory; it must be one greater than the number

of graphics blocks in existence at any one time. DGINIT zeros

out the directory, whose words are subsequently filled by

other system subroutines. Each word in the directory cor-

responds to a single graphics block. When a new block is

created, the first non-zero word in the directory is filled

with data for that block. As the blocks are created, they

are numbered consecutively in ascending order.

2. Graphics Output Subroutine - GRAPHO

This routine outputs the graphics data block (image

array) to the AGT/10 and GATED for presentation on the

cathrode ray tube. No editing may be performed at the

graphics console on blocks which have been output by GRAPHO.

A typical call would be of the form:

CALL GRAPHO (IDEV, IMAGE, NWORD, IBLK, IER)

IDEV specifies to which AGT/10 the block is being passed.

IMAGE is the first word address of the graphics data block

being output. NWORD is the number of words in that block,

and IBLK is the block number (as referred to in the section

above). Graphics data blocks contain two types of words:

The first (header) word, and as many data words as are needed

to specify the figure which is to be drawn. Figure 2(a)

square. Thus, X; and Y. mustbe between -512 and +511 ifthe figure is to be drawninside the 10" square.'

3. Graphic Output with Response Subroutine-GRAPHR

This subroutine is called with exactly the same para-

meters as GRAPHO. In addition to passing the image array for

display on the cathode ray tube, GRAPHR also causes GATED to

enter an edit mode for the block concerned. The block may

then be edited at the AGT/10 display. The FORTRAN programmer

would normally cause his program to loop until editing opera-

tions were complete.

CALL GRAPHR (IDEV, IMAGE, NWORD , IBLK, IER)

Graphics Input Subroutine - GRAPHI

This subroutine inputs an image array from the AGT/10

to the XDS 9 300.

CALL GRAPHI (IDEV, IMAGE, IBLK, IER)

IDEV, IBLK and IER are as defined above. IMAGE is the first

word address of an integer array where the data block is to

be placed.

5

.

Special Routines

To construct a graphic image requires a great deal of

bit processing. To allow the user to avoid these difficulties,

the functions IHEAD and IPACK were created. In addition there

is a special subroutine, UNPACK, which extracts values from

the fields of the image array words for use as FORTRAN

variables

.

a. Function to Create Header Word - IHEAD

IMAGE (1) = IHEAD ( IDSH , INT)

In this example, IMAGE (1) is the header word'

19

of an image array. IDSH and INT are variables which MEAD

will place in the VM and INTENSITY fields, respectively (see

Figure 2 (a) )

.

b. Function to Create Data Word - IPACK

IMAGE (I) = IPACK (X 7 Y, IDM)

thIn this example, IMAGE (I) is the 1 word in a

graphics data block. X, Y, and IDM are variables which

IPACK will place in the X., Y., and DM fields, respectively.

c. Subroutine to Extract Values from the Image -

UNPACK

CALL UNPACK (IMAGE (I) , X, Y, IDM)

In this case, IMAGE (I) is the i word of a

graphics data block. X, Y, and IDM are variables where

UNPACK will place the values from the X., Y., and DM fields,

respectively. In other words, this subroutine performs the

reverse process of IPACK.

C. GATED, EXISTING GRAPHICS AND TEXT EDITOR AT THE NAVAL

POSTGRADUATE SCHOOL.

1. Philosophy of GATED

The existing graphics and text editor program, GATED,

resides as a permanent file on the system disk packs. It

essentially performs three tasks [6]:

(1) Refreshing the cathode ray tube display.

The screen is refreshed as part of the pro-

gram's major cycle at about 40 frames per

second, except during data transfers to or

from the XDS 9 300. During these data

transfers, no refresh is performed.

20

(2) Communicating with the graphics con-

sole operator. GATED uses the CRT

display, teletypewriter, lightpen,

and function switches to communicate

with the user. The user can create

text and graphics data or edit existing

data. For simplicity one can think of

creating data as editing an empty data

block. During editing of data, the

screen will be refreshed, but data will

not be transferred between the AGT/10

and the XDS 9 300.

(3) Communicating with the FORTRAN graphics

package in the XDS 9 300 (described in

III B. above)

.

GATED divides its data into two sets, graphics and

text. This thesis has concerned itself only with graphics

data, as it has been in that area that the design improve-

ments have been made. The graphics data blocks, as de-

scribed in III B. above and Figure 2(a) , are transferred via

the interface to the AGT/10. GATED displays all of the data

blocks that is has stored in the AGT/10 memory. The FORTRAN

graphics package can only send or retrieve one block of data

at one time. The user can edit (or create) only one block

of data at a time. To edit a block, the following steps

must be performed in the prescribed order [6]:

1. Specify the user's desire to edit data.

21

2. Specify which block is to be edited or that

a new block is to be created. GATED creates

an empty block in the latter case.

3. Enter the edit mode.

4. Edit the block.

5. Terminate the edit mode.

Most of the above steps are accomplished by pushing the

proper function switches . This is worthy of mention in that

it will be shown that RADIK, while preserving the basic

editing philosophy of GATED, allows more flexibility in the

use of the function switches and other hardware devices

(i.e., joystick and variable control dials).

2. Data Structure of GATED

GATED performs the necessary shifting and masking

required to change the 24 bit XDS 9 300 data word into a

30 bit AGT/10 data word (see Figure 2(b)). A zero in

bit 14 of the header word will produce a picture with solid

lines, while a one in bit 14 will produce a dashed figure.

Bits 15-29 are used to specify the amount of intensity with

which the block is to be displayed. Bits 1-13 are unused.

In the data words, bits 1-13 are used for the X co-

ordinate for the endpoint of a line, while bits 15-28 are

used for the Y coordinate of that point. A zero in bit 29

will result in a move to that point, whereas a one in bit

29 will produce a draw. Bit 14 is unused and always set

to zero.

There is a subroutine in GATED (SHRNK) , which is used

to recover unused storage from graphics data blocks. SHRNK

22

searches the graphics data block for two or more consecutive

moves and deletes all but the last move of the set of con-

secutive moves. Since moves are not displayed, no effect

is seen on the screen display, while the memory words pre-

viously occupied by the moves are freed for further utili-

zation. As will be seen later, this subroutine had to be

modified for inclusion in RADIK in order to accommodate a

new graphics block data structure.

3. Control of GATED

The user utilizes the function switches, teletype-

writer and lightpen to provide input to GATED. The function

switches provide controls for branching to various modes and

subroutines which will perform the necessary steps for

creating new data blocks or referencing existing data blocks

and allowing them to be edited. An overlay labeled "GATED",

when placed over the function switches, will indicate what

action will be performed by depressing a particular switch

(see Figure 3) . The upper left hand function switch is

designated FNS1 and the lower right hand switch is designated

as FNS16. [6]

IV. RADIK, AN INTERACTIVE GRAPHICS AND TEXT EDITOR

A. OBJECTIVES

GATED provides for AGT/10 stand-alone graphics operations

as well as XDS 9 300-AGT/10 graphics displays. However, it

is felt that, in both modes, GATED fails to fully utilize

existing graphics hardware. RADIK is an attempt to more

fully utilize available interactive graphics hardware, using

the philosophy and program structure of GATED as a base from

which to build. Specifically, the following goals were

proposed as reasonable objectives for the work presented

in this thesis:

(1) The display hardware is capable of receiving vary-

ing inputs for use in the setting of scale factor, DX (change

in X coordinate) and DY (change in Y coordinate) . GATED,

however, fails to take advantage of this fact and sends values

which always set scale factor to unity and DX and DY to zero.

It was desired, then, to be able to pass scale factor and

DX/DY information from the XDS 9 300 to the AGT/10 as part of

a graphics block.

(2) To utilize the function switches for editing of

graphics displays, both in stand-alone and XDS 9 300 modes of

operation. GATED presently limits the use of the function

switches to those operations denoted in Figure 3 and described

in [6].

(3) To utilize the settings of the function switches,

variable control dial potentiometers and joystick potentiometers

25

as control information for the XDS 9 30 FORTRAN programs.

GATED, although it samples the function switches, does not

interrogate the variable control dials or joystick, and

furthermore, does not have the capability to transmit any

of the above listed information to the XDS 9300.

(4) To make the necessary changes in the XDS 9 300

monitor and FORTRAN graphics package to accommodate objectives

(1) , (2) and (3). This would require modification of the

data structures themselves, as well as writing FORTRAN cal-

lable assembly language subroutines to process the desired

information.

The objectives stated above indicate that the work pre-

sented in this thesis encompassed both the AGT/10 and XDS

9 300 computers. As mentioned in III above, these computers

differ significantly in their design philosophy and operating

characteristics. Since the work required an intimate know-

ledge of the internal structures of each machine, it was

decided that it could best be performed by two people. Ac-

cordingly, the author is responsible for the AGT/10 software

discussed herein, and Lcdr Ralph H. Stowell, Jr., USN , is

responsible for the work performed on the XDS 9 300. Close

communication was required throughout the design process,

however, in order to be able to accommodate alterations on

both sides of the system and to establish the required inter-

face. The major portion of this work, then, consisted of

assembly language (ADEPT) programming on the AGT/10 and as-

sembly language (META-SYMBOL) programming on the XDS 9 300.

FORTRAN programs were used to test and demonstrate the work.

26

B. RESULTS

1. Data Structures

a. XDS 9300

Perhaps the single most important concept upon

which this work relies is the change in the XDS 9 300 data

structure for graphics blocks. In order to transmit scale

factor, DX, and DY as inputs to the AGT/10 graphics and text

editor, a radical change was needed in the configuration of

the image array. The result is that scale factor information

has been placed in the previously unused portion of the header

word, while DX and DY are placed in the second word of the

array, as illustrated in Figure 4(a). Remaining data words

of the block are left unchanged. While this requires one

more word of storage for a given block, the advantages gained

make this cost trivial.

Previously, if the user had desired to change

scale factor or DX/DY, it could never actually be accomplished

Such changes could be simulated, however, by running each

of the data words through a FORTRAN "DO" loop to change the

X and Y coordinates in such a manner as to effectively change

the size or displacement of the figure being displayed. With

the new block structure, only the word with the desired infor-

mation need be modified (i.e., header word or second word)

.

This saves execution time (one assignment statement versus

the "n" assignment statements and conditional branch required

for a "DO" loop), and also, retains the original coordinate

information of the array.

28

To implement such a data structure, new routines

were required to build the graphics data block's first two

words. This was accomplished in the following manner:

(1) The header word was built using a specially

written FORTRAN subroutine, IPAKM, which is listed in COM-

PUTER PROGRAM 1.

(2) The second word was built using the function

IPACK (described above) with parameters DX, DY and zero.

FORTRAN statements for building these first two words of an

image array take the following form:

IMAGE (1) = IPAKM (SKAL, IDSH, INT)

IMAGE (2) = IPACK (DX, DY , 0)

Where SKAL is an octal number in the range 0000 = SKAL = 1776 .

8 8

The choice of this range of numbers is significant and de-

serves further comment. Since 11 bits (bits 0-10) are used

for SKAL, the largest positive number that could be re-.

presented is 3776 . The hardware of the AGT/10 will, in8

fact, translate 3776 into a scale factor of unity. However,8

since one of the desired functions of RADIK was the ability

to magnify a figure as well as scale it down, 1776 _ was

chosen to represent unity to the FORTRAN programmer. In

this way, the user will be able to enlarge a figure to twice

its original size. It should be pointed out that only 11

bits are used for scale factor information; therefore, no

odd numbers can be used, since this might result in setting

bit 11 (and therefore IDSH) to 1, even though a solid figure

is desired. IDSH, and INT are integer variables as described

previously. DX and DY are values in the same range as for

29

X-Y coordinates. The parameter is passed to IPACK for the

second word, since it might otherwise be interpreted as a

draw. No changes were necessary for constructing the re-

maining words of the data block, and either GRAPHO or GRAPHR

could still be used to output the block to the AGT/10

.

b. AGT/10-RADIK

Since the new XDS 9 300 data structures are the

most important single concept upon which this work relies,

they are responsible for much time and effort to facilitate

their use. Since the program structure of GATED was being

used as a base, the new block structure being transmitted by

the XDS 9 300 necessitated extensive program changes in order

to be accommodated by the graphics and text editor. The

physical size of the program (80 pages of listing) dictated

many detailed alterations, mostly in the area of indexing and

indirect addressing. Other factors dealing with the data

structure also had to be considered; whereas GATED had always

set scale factor to unity and DX/DY to zero, RADIK checks

the first and second words of an image array for that infor-

mation and transfers it to the appropriate hardware for im-

plementation. The stand-alone mode of the AGT/10 had to be

considered as a separate problem, since the AGT/10 creates

empty blocks in that mode. In addition to the same indexing

and indirect addressing problems as were encountered in the

XDS 9 300-AGT/10 mode, it was required to set scale factor

initially to unity and DX/DY to zero. In addition, since the

function switches were to be used for performing new routines

30

in both modes, variables which were common to both modes had

to be used when implementing that portion of the work.

2. Routines

Several new routines were written in order to allow

the user to have more flexibility and versatility in FORTRAN

programming and to utilize available hardware control devices

in both stand-alone and XDS 9 300-AGT/10 operation,

a. AGT/10 - RADIK routines.

The portion of the work presented here consisted

of implementing several function switches to perform graphics

editing functions while RADIK is in a graphics wait mode.

Previously, the switches were not used for functions other

than those depicted in Figure 3. The switches and their new

functions are listed below:

FNS1 - translates figure to the left

FNS2 - translates figure to the right

FNS3 - scales figure down

FNS5 - translates figure upward

FNS6 - translates figure down

FNS7 - magnifies figure

FNS8 - rotates the figure

In order for a user to edit a graphics block he

must perform the following steps in order [6]:

1. Select the graphics edit mode.

Depress GRAPHICS EDIT (FNS2) . The message

"GRAPHIC BLOCK SELECT MODE BL0CK1" will appear on the lower

edge of the screen if operating in conjunction with the XDS

31

9300. Otherwise the message "GRAPHIC EDIT REQUEST" appears

at the bottom of the screen.

2. Select the graphics block to be edited.

Depress NEXT BLOCK (FNS5) once for each block to

be skipped. If the desired block has been passed, depressing

PREVIOUS BLOCK (FNS6) will back up one block at a time until

the desired block is reached.

At this point, it is also possible to create a

new block. To do this, depress NEW BLOCK (FNS7) . RADIK

allocates all of free core to the new graphics block. This

new block becomes the next sequential block. When edit is

terminated, the new block will be shrunk to the number of

words actually used, thus allowing the unused words to be

returned to free core.

3. Start the edit mode.

Depress GO EDIT (FNS8) to enable the graphic edit

mode for the selected block. The following message will ap-

pear at the bottom of the screen "GRAPHIC EDIT MODE BLOCK"

followed by the block number. If a block has been output

from the XDS 9 300 via a GRAPHR, these first 3 steps are

performed for the user by RADIK.

4. Graphics editing operations.

It is at this point that the function switches

listed above are enabled for their new editing capabilities.

Figure 5 depicts an overlay for the function switches for use

with RADIK. All of the new functions will be performed con-

tinuously if the associated switch is held down. Depressing

FNS4 will end the editing process (as in GATED) and the. block

will contain the information associated with the figure's

present perspective and position on the screen. If operating

with the XDS 9 300, this information will then be transmitted

to the XDS 9 300.

An interesting difficulty arose during this portion

of the work. While editing, if FNS8 is held down long enough,

one will notice a gradual diminishing in size of the figure

being edited. This is due to the accumulation of small

round-off errors which are inherent in the AGT/10 multi-

plication process. While it appears that the figure is

diminishing in scale, in actuality the scale factor is not

being changed at all; however, each data word's X and Y

coordinates are being altered by minute amounts. While this

is obviously undesirable, the only solution would be to

limit the number of words in a graphics data block so that a

temporary block of arbitrary size could be used to store the

original coordinate data and counteract the round-off errors.

This would not only restrict the user, but would also in-

crease RADIK's storage requirements and execution time. Thei

i

proposed corrective action is to use FNS8 for a short period

of time (not a severe restriction, since most users would

desire less than 360 of rotation for a change in perspective)

,

and then correct the size by using FNS7 to magnify the figure.

The structure of the data words themselves also

gave rise to a minor difficulty during the implementation of

the new editing functions. It was noticed that, when tran-

slating a figure horizontally using FNS1 and FNS2, there was

a very slight change in the figure's vertical displacement.

34

This was due to the method being employed to effect the

horizontal translation. The method consisted of adding (or

subtracting) a small increment to the DX field of the second

word in the graphics block whenever FNS1 (or FNS2) was de-

pressed. However, since only half of the second word is

being used for the DX field, the addition of this increment

would sometimes cause an "overflow" into that portion of the

word which is used for DY. This was solved by extracting the

information from the DX field, incrementing it, and then in-

serting it back into the second word. In this way, the DY

field will not be inadvertently changed.

RADIK also had to be modified due to the addition

of three new routines, VCD, JOYSTK, and SWITCH, to the XDS

9 300 FORTRAN graphics package. As their names imply, these

routines are used to obtain information from the variable

control dials (VCD) , joystick (JOYSTK) and function switches

(SWITCH) . These routines were written as part of the work

for this thesis and are described in IV. 2b. below. The

writing of these routines necessitated modifying RADIK to:

(1) Receive the new routines' request for

information;

(2) Obtain the desired information; and

(3) Transmit the information to the XDS 9 300.

Obtaining the desired information (function switch states,

variable control dials and joystick potentiometer values)

was not a problem. In fact, procedures already existed* to

procure the states of all the above listed devices. What

was needed, then, was a way to communicate the information

35

request and reply between the XDS 9 30 and the AGT/10. This

was accomplished by altering the XDS 9 300 monitor to handle

the new routines in a manner similar to that used for other

library subroutines. In addition, communications routines

were built into RADIK to process the new routines in a manner

similar to GRAPHO and GRAPHR.

b. XDS 9 300 Subroutines

Three subroutines were written to allow the XDS

9300 user to request and receive the status of the variable

control dials (VCD) , joystick (JOYSTK) , and function switches

(SWITCH) . VCD and JOYSTK are written in META-SYMBOL , but

are FORTRAN callable. SWITCH is written in FORTRAN. All

are included in Computer Program 1. The META-SYMBOL routines

have been incorporated into the XDS 9 300 subroutine library

and have been fully tested in a number of programs.

1. VCD

VCD is the assembly language, FORTRAN callable

subroutine which requests and receives the readings of all

six variable control dial potentiometers. A typical call

would be of the form:

CALL VCD (IDEV, IDIAL, DIAL, IER)

IDEV is the number of the AGT being used. IDIAL is the first

word address of an integer array of dimension six, and DIAL

is the first word address of a real array of dimension six.

IER is the error flag used in all graphics subroutines. As

a result of a call to VCD, values of the six variable control

dial potentiometers are placed in DIAL (1) through DIAL (6)

.

36

2

.

JOYSTK

JOYSTK is the assembly language, FORTRAN callable

subroutine which requests and receives the readings of all

three potentiometers which are attached to the joystick.

A typical call would be:

CALL JOYSTK (IDEV, JOY, AJOY , IER)

IDEV is the number of the AGT being used. JOY is the first

word address of an integer array of dimension three, and

AJOY is the first word address of a real array of dimension

three. IER is the error flag used in all graphics subroutines

As a result of a call to JOYSTK, the values of the three joy-

stick potentiometers are placed in AJOY (1) through AJOY (3)

.

Note that both VCD and JOYSTK are called with

what appears to be an "extra" parameter, namely the integer

arrays IDIAL and JOY. This is due to the inherent nature of

the communications link between RADIK and the XDS 9 300. The

analog values of the potentiometers are digitized and trans-

mitted as single words to the XDS 9300. Since an integer

variable occupies one word of storage in the XDS 9300, these

digitized values are first placed in the integer arrays. A

specially written subroutine, XFORM, is then called from

within VCD and JOYSTK. XFORM transforms the single word

digitized quantities into real variables and places them

in the double word real arrays.

3. SWITCH

SWITCH is a FORTRAN subroutine which requests and

receives the status of the 16 function switches. All 16

switches are interrogated to see whether or not they are set,

37

and this information is passed to the XDS 9 300 in the lower

16 bits of a single word. A logical function, CHANGE, is

then used to see whether a particular switch is set or not.

Typical calls to SWITCH and CHANGE would be:

CALL SWITCH (IDEV, ISWITCH, IER)

IF (CHANGE 3, SWITCH)...

In this example, IDEV and IER are the AGT number and error

flag respectively. ISWITCH is the integer variable used

to store the information and 3 is the number of the switch

whose status is being requested. SWITCH and CHANGE, then,

provide a means for using the setting of the function switches

as branching controls for FORTRAN programs.

IV. APPLICATIONS

The results discussed in Section III allow the user much

more flexibility in utilizing the available equipment. Tran-

slation, rotation, and scaling may be performed in conjunction

with the XDS 9 300 or in AGT/10 stand-alone mode. One im-

mediately obvious advantage over GATED is that the user may

now use GRAPHR to transmit a graphics block from the XDS 9 300

whose data words are empty, draw the basic picture on the

screen with the lightpen, and then translate, rotate, and

scale the figure to his specifications before sending the

information back to the XDS 9 300. Previously, the user would

have had to make computations and measurements before writing

his program to obtain the desired picture. Even then, a figure

might not have appeared exactly as desired, so that ad-

ditional time consuming measurements and computations had to

be made. Similarly, the user may now arrange several figures

on the screen in their desired relationships to one another

by use of the function switches to achieve the proper con-

figuration in an on-line, interactive manner as opposed to

lengthy "hit and miss" techniques.

In addition to their editing capabilities, the function

switches, along with the variable control dials and joystick,

can now be used as controls for the branching of FORTRAN

programs. Of course, they may also be used to directly

change a display by assigning the values to a graphics data

block word.

39

Applications of RADIK and the new FORTRAN graphics package

will be limited only by the imagination of the programmer.

No applications have been lost from the existing system and

the new data structures and available hardware open up count-

less new possibilities.

40

V. CONCLUSIONS

A generalized graphics display system, one which would

allow a user with a specialized visual display requirement

to produce the display with relative ease, would have to

meet such general criteria as the following [2]

:

(1) It must be on-line or at least closely appear to

be so. This tends to reduce trial-and-error frustrations

to a minimum.

(2) It must be conversational, in that every user re-

quest is met with a response from the computer. This is

important in that certain operations may not have immediately

obvious results.

(3) It must be versatile by offering facilities both

for constructing pictures out of primitive geometries and

symbolic figures, and for performing transformations upon

such pictures.

(4) It must offer continuity between constructs by

having facility for dynamic storage of partial or complete

pictures, both internal and external to the computer. A

user should be able to store, retrieve, and superimpose

previously drawn pictures.

It is felt that the graphics display system at the Naval

Postgraduate School Computer Laboratory will meet these

criteria, if RADIK is implemented as the graphics and text

editor and the required associated changes are made in the

XDS 9 300 monitor system and subroutine package.

41

If implemented, the largest contribution that the work

presented in this thesis will make to the graphics display

system at the Naval Postgraduate School is the increased

versatility and flexibility of FORTRAN programs in controlling

a display on the AGT/10. This has been accomplished simply

by utilizing more fully the available interactive hardware

configurations

RADIK is an interactive graphics and text editing system designedfor use with an ADAGE AGT/10 graphics computer, either in a stand-alone mode, or in conjunction with an XDS 9300 computer. The thesispresents an overview of desirable attributes and capabilities of aninteractive graphics display system. A description is given of thegraphics display system presently in use at the Naval PostgraduateSchool Computer Laboratory, along with its apparent deficiencies.Objectives for an improved graphics and text editor are presented,in addition to results achieved and problems encountered while de-signing RADIK. A brief summary of results and applications is presentedand implementation of RADIK is proposed. Computer programs developedduring the work are appended for reference.
