(ABSTRACT)
The personal computer is rapidly finding its way
into the architectural working environment, at this
time however it is used mostly as a drafting tool. This
thesis is an investigation into programing that would
allow the computer to become a design tool.
The issues that are dealt with in this thesis
include an easy to use user interface that will not
inhibit the design process, and develop a system that
will allow design changes and additions to a model in a
three dimensional sketch like ability.
Three dimensional models of paper, clay, wood and
other materials have been used to create designs, and
aid the designer in making decisions. This type of
medium is difficult to make changes, and because of the
scale of such materials it becomes difficult to work on
interior spaces, thus more attention is usually placed
on the exterior design. With the use of the computer
these limitations may be eliminated, and the designer
may create a design from any perspective or view point.
ACKNOWLEDGEMENTS
I would like to offer a special thanks to Robert
Schubert, Dennis Jones and John Wade for their support and
advice throughout this study. I would also like to
recognize John and Dennis's work on the computer that has
inspired me to produce this thesis.
A warm appreciation is extended to my parents for
their support and sacrifices that made this study
possible.
Finally, I am most grateful for
precious loved ones.

INTRODUCTION:
In the last few years the introduction of the
Personal computer has brought Computer Aided Design (CAD)
to the small office and home. As the trend continues in
the next few years we will have mainframe power available
in the Personal Computer. Already many hardware
developers have created plug-in boards with a very fast
drawing speed, and call up graphic functions in firmware.
With the introduction of these boards greater speed, and
more flexibility in programing will be achieved.
At this time there are a great many three dimensional CAD
programs available, many are well suited for engineers,
and draftsmen but there are few that take into account the
needs of the designer. The designer's needs are much
different than that of the draftsman or engineer. The
designer needs a flexible program to use in case of
changes, and a visual program with the ability to observe
and compare. Because designers tend to be visual,
visualization is primary. Aid from the computer will make
the vision of the designer a reality in a matter of
minutes. If the designer is not satisfied with a design
then changes can be made neatly and quickly. The computer
gives instant feedback, which can speed up the entire
design process.

Three dimensional models are an essential tool for
creating designs; however, there are few methods available
that create 3D models quickly. Now with the introduction
of CAD, models are created, transformed, and viewed from
any perspective. CAD has an advantage in that the model
can be viewed from the inside out as well as the outside
in. This will aid the designer in creating new concepts
and better integration of ideas. At the moment there are
several limitations that exist before CAD can be used as a
designing tool. The first and most important being that
most designers are unfamiliar with the use of computers.
Second most programs on the market today are very
difficult to learn and work with. Once the programs
become more orientated to designers and become easier to
use, then more designers will turn to CAD for their
designing needs.
The purpose of this thesis is to create a solid
modeling program that can be used to create architectural
designs, jewelry, furniture and 3D art forms on the
computer.
3
By developing the design program the following
objectives should be accomplished:
Create a 3D design program for my personal use.
Develop a driver for the Matrox SM-640 graphics board.
Develop skills to understand how to program other
graphics boards on the market.
Develop skills in the C programing language.
Gain a better understanding of the computer operating
system (DOS).
Learn general computing skills.
Gain a better understanding of Computer Aided Design.
Be more aware of available computer hardware.
4
The scope of the thesis includes only 3D solid
modeling at this time. Elements that create a model are
handled in the way one would construct a block type model.
The programs methods of designing a model are similar to
that of a sketch book. A designer sketches are not so
concerned with exact dimensions, but more with the
relationships of parts. Changes may be made easily so the
designer can visualize a wider range of possibilities. The
designer has the ability to program in exact dimensions;
however, one of the strengths of the program is the
ability to allow the designer to also make visual
judgments, as in the sketch book. Therefore this program
should not be seen as a drafting tool, but a sketch tool.
MODELING DESIGN PROCESS :
One of the main aspects of this program is its ability
to allow the designer to test the relationships between
elements before making a commitment to their existence in
the work space. This is one of the computers strong
points, but is not fully utilized in most existing CADD
programs. Most other modeling mediums are not as flexible
as well. During the design process these changes and
comparisons are essential to allow
range of possibilities. If the
flexible, that inflexibility may
process.
the designer a full
drawing medium is not
influence the design
The program begins by presenting the designer with an
empty work space, this work space may be increased or
decreased in size at any time. Once the work space as been
defined a location indicator called a cursor is shown at
the origin 0.0, 0.0, 0.0 which is located at the center of
the viewport. The designer is then automatically put into
the object design phase, it is the main working
environment. The object design phase includes:
5
6
Volume Definition --Defines primitive, swept solid, extruded solids and composites
Translation --Defines the location of an object
Solid Description --Defines color, translucency, facets and shading
Transformation
Revaluate
--Defines Modeling transformations that effect the object
--Deletes objects from the work space
These commands allow the designer to move, transform
and define objects in three dimensional space before
making a commitment to include that object in the work
space. In this phase the object will appear only in
wireframe. While in the Comparison Testing phase the
object may be compared with existing objects in the model.
From there the designer enter into the Evaluation Phase.
At this point the designer may accept or reject the
present configuration. If the configuration is
unacceptable the designer may continue with the Object
Creation Phase. If the model is satisfactory the Model
Creation Phase is activated by pressing the space bar"
and the object with all of its attributes is drawn to the
screen and added to the modeling file. The Revaluate Phase
allows the designer to go back and remove any object that
has been added to the model.

GENERAL OVERVIEW OF SYSTEM
The program begins by entering automatically into the
main function. It then defines all global variables, and
sets all graphic attributes, these attributes
include: window size viewport size viewing reference point clipping planes viewing distance lighting direction and intensity shading type color look up table
Once the attributes are set they are stored in a file
called SETUP.D . SETUP.D is called up whenever there are
any changes made to the setup attributes. The main
function also creates COMMAND.D , this is the active work
file, it will contain location of primitives, objects,
modeling transformations, lighting attributes and color
used in creating a model. SETUP.D and COMMAND.D together
make up the Command List, which is used to recreate the
model at another time.
8
Once the main function creates the command list files
it then opens up the keyboard function which gives access
to cursor, drawing and main menu functions, the user will
remain inside the main and keyboard function until the
user exits the system.
The cursor function draws on the screen a 3D
cross-hair that locates the current X, Y,and Z locations.
If a primitive or composite object is chosen the cursor
will take the shape of that object, and draw a fully
shaded representation of that object, once the drawing
command is activated. The drawing function also opens the
command list file and sends drawing attributes to the file
along with the chosen object. After these commands are
sent to the file a permanent work file is created, and the
file is closed. The program then enters back into the
keyboard function, and waits for another input command.

SRTUP FUNCTIONS:
The first part of the Main Function consists of a
function that defines all global variables used in the
program. Once the variables have been defined, they are
then assigned values, and set to the modeling attribute
function, which sets the graphic screen to the assigned
values. The program then creates two files SETUP.D and
COMMAND.D SETUP.D is responsible for all initial
attributes and viewing commands. COMMAND.D is responsible
to record all changes of the initial attributes and
additions of objects with there locations. Together they
are called the Command List. The Command List when passed
through the program will recreate any drawing or model
previously created on the screen.
After the Command List files have been set up the
program enters into the menu setup function. This function
displays the main menus accessible from the keyboard. At
this point the program enters into the keyboard function
which wait for the users input. The keyboard function is
the most active function in the program, and can branch to
most any other function in the program. The main branches
include: menu branch, translation branch, and drawing
branch.

TRANSLATION FUNCTION:
One of the most important and most used functions is
the Translation Function it allows the user to move an
object freely on the screen, calculate distance from the
last entry and stores X, Y and Z locations. The
Translation function is actually a group of separate
subfunctions that are accessed through the "num" key pad.
Each key will activate a specific function that will move
the object in a particular direction, they are as follows:
KEY FUNCTION
moves z axis negative 0 moves z axis positive 1 moves x axis negative & y axis negative 2 moves y axis negative 3 moves x axis positive & y axis negative 4 moves x axis negative 5 6 moves x axis positive 7 moves x axis negative & y axis positive 8 moves y axis positive 9 moves y axis positive & x axis positive

move {Z+) L.__.roove (Z-)
Each time a key is pressed it will automatically move
the cursor or object in the chosen direction. At the
bottom of the screen there is a constant read out of the
present coordinate location, as well as the last modeling
origin entered.
COORDINATE INFORMATION
XD=0.00 X=0.00
YD=0.00 Y=0.00
ZD=0.00 Z=0.00
ROTATION INFORMATION
RX=O:O RY=O:O RZ=O:O RX=O:O RY=O:O RZ=O:O
Once the proper coordinates have been located the
space" bar should be pressed, this will enter into the
Drawing Function, and record the object and its location.
The Command used for translation is MDTRAN rx, ry, rz. The
rx, ry and rz represent relative X, Y and Z coordinates.
For example : MDTRAN 50.0, 0.0, 0.0 will move the drawing
point to 50.0, 0.0, 0.0. If it is entered twice the active
point would be 100.0, 0.0, 0.0.

DRAWING FUNCTION
The Drawing function is very closely tied to the
Translation Function, Cursor Function and Main Menu
functions. Whenever a change in status of the
coordinates, cursor shape or modeling attributes are made,
the drawing function records these changes in the Command
List. After a Command List of objects and modeling
attributes is created, the model can be recreated at
another time. The Drawing Function and Main Menu functions
act together to const~uct the Command list. The Drawing
Function is activated by pressing the "Space" bar, once
this is done the XOR drawing mode is turned off and the
shading attributes are set. After this is accomplished the
cursor Flag is checked to see which primitive or solid is
to be drawn at the active coordinate location. Next the
rotation attributes are arranged so that the proper order
of execution will take place. Then COMMAND.D file is
opened and the solid along with its modeling attributes is
written to the file. If any rotation or scaling attributes
are active the modeling matrix most be reset to the
default values, This is because rotation and scaling
effects the entire modeling matrix not just the object as
it may appear when running the program.

MAIN MKNU FUNCTIONS:
From the Keyboard Function eight main menus or
functions are accessible, and they represent eight
specific groups of functions that are used in the creation
of a model. Each group is represented in an abbreviated
form at the top of the screen. {see fig below}
DIMN SOLD MODL ORGN VIEW COLR RMOV WNDW FILE ERAS
The menus and functions are arranged in an order of
most frequent use. Each four letter abbreviation
represents the following function or menu.
DIMN SOLD MODL ORGN VIEW COLR RMOV WNDW FILE ERAS
DIMENSION FUNCTION SOLID MENU MODELING MENU MODELING ORIGIN FUNCTION VIEW MENU COLOR MENU REMOVE OBJECT FUNCTION SET PLAN, ELEVATION OR MULTIPLE WINDOW SENDS OR RECEIVES WORKING FILES ERASES THE ENTIRE SCREEN
The main menus will then branch to more specific
sub-menus. Many of the major functions such as translation
and drawing are even accessible from within the sub menus.
The sub-menus will always return back to the main menu by
pressing "Esc".

21
DIMENSION FUNCTION:
The dimension function allows the user to increase or
decrease the length, height or width of a block primitive
and the radius of a sphere or cylindrical primitive. Once
the function is entered by pressing "d" .The dimension
function will be activated, then the num keys will
control expansion or contraction along the width, length,
height or radius. The amount of expansion is determined by
the value of the grid spacing which can be adjusted by the
plus and minus keys.

EJ2]@] + <~-increase grid space
I a ~ m=J CJ ._____. decrease length __J L__increase length
22
The dimension function works by adding or subtracting
the grid value to the dimension value. Once the value are
defined then they are used in the solid function to
specify a height, length, width or radius, an example of
this is as follows:
PSOLID 4 WIDTH HEIGHT LENGTH
PSOLID - command for solids
4 - sets solid mode to block
WIDTH - defines width value
HEIGHT - defines height value
LENGTH - defines length value
In order to draw a block with a width of 100, height
of 50 and length of 20. The command
PSOLID 4 100.0 50.0 20.0
must be created and sent to the Command List.

24
SOLIDS MENU :
The Solids Menu gives the user access to a set of
functions that will draw a set of primitives, swept solids
or composite solids. The first function will display the
selection of solids available to the user at the top of
the screen like the figure below.
BLOC COLM TUBE SPHR WEDG PYRY RING EXTR LATH MULT
The solids are arranged in an order most frequently
used, and a four letter abbreviation is used to symbolize
each object, the abbreviations are represented as:
BLOC COLM TUBE SPHR WEDG PYRY RING EXTR LATH MULT
BLOCK CYLINDER, COLUMN TUBE SPHERE WEDGE CONE, PYRAMID TORUS, RING, WHEEL EXTRUDED SOLID TURNED SOLID COMPOSITE SOLIDS
In order to activate one of the solid commands press
the first letter of the abbreviation on the keyboard. Once
this is done a value is set to a variable that corresponds
to the assigned solid, and the cursor will become that
solid. The cursor will remain that solid until a change is
made. If the "space" bar is pressed it will activate the
drawing function. The selected solid will then be drawn
to the screen and sent to the Command List along with
other attributes that define the solid.
25
The command used to activate any primitive solid is
PSOLID, then a mode zero to six is used to specify the
type a solid. The following modes are used:
CYLINDER = 0 CONE - 1 -SPHERE = 2 TORUS = 3 BLOCK = 4 WEDGE = 5 TUBE = 6
The mode number is written directly after the solid
command, such as for a sphere. " PSOLID 2 " After the mode
number comes the dimension information. Each primitive has
its own format, they are as follows:
CYLINDER - PSOLID 0' RADIUS, LENGTH CONE - PSOLID 1 ' RADIUS-TOP, RADIUS-BOTTOM, LENGTH SPHERE - PSOLID 2, RADIUS TORUS = PSOLID 3, RADIUS-INTERIOR, RADIUS-EXTERIOR BLOCK = PSOLID 4, WIDTH, HEIGHT, LENGTH WEDGE = PSOLID 5, WIDTH, HEIGHT, LENGTH TUBE = PSOLID 6, RADIUS-INTERIOR, RADIUS-EX, LENGTH
The mode number is activated through the solids menu.
Once the selection is made a number is assigned to
variable that dictates the cursor shape and the primitive
that will be drawn.

28
Because swept, extruded and composite solids require
more information another format is used, for swept and
extruded solids the Command SSOLID is used, the extruded
solid uses mode 1 , and swept solid uses mode 2. Then
following the mode number is a closed 2D vector that is
either extruded along a sweep vector, or rotated around
the Y axis in a counter-clockwise direction. In order to
draw a prism shape, the command format is as follows:
SSOLID 0, NUMBKR-OF-VKRTICKS, X Y POINT SKT
EXAMPLE: for prism with points 0.0, 0.0, 0.0, 100.0, -100.0, 100.0, 0.0, 0.0
SSOLID 0, 4 0.0, 0. 0,
-100.0, 0. 0,
0.0 100.0 100.0
0.0
For Composite Solids the Command List Definition or
Solid Definition commands may be used. They are as
follows:
COMMAND LIST DEFINITIONS
CLBEG num - begins Command List num = {0 ... 256} CLEND - ends current Command List CLRUN num - runs list num
SOLID DEFINITION COMMANDS
SOLBEG num - begins Solid List num = {0 ... 256} SOLEND - ends current Solid List SOLRUN num - runs list num
29
The advantage to using one over the other is the the
Command List is faster and may include any other command
to define an object, while Solid Definition will allow

MODELING MENU :
The Modeling Menu gives access to a set of functions
that will effect certain attributes associated with a
primitive or object. These attributes are presented at the
top of the screen after the user presses the key "m" for
the modeling menu. The modeling menu screen display will
be drawn at the top of the screen, like the figure below,
the set of abbreviations that are displayed will
correspond to a set of modeling functions.

This set of modeling functions will give access to
another set of functions related to the heading, or is
only a single function. In order to activate a command
press the key of the first letter of the word or
abbreviation. If the word represents a function it will be
activated, if it branches to another menu it will present
the user with a new set of functions.
ROTATION FUNCTIONS:
The Rotation Functions branch to sub-functions Rotate
X a.xis, Rotate Y a.xis and Rotate Z axis. Each of the
different axis rotation functions are displayed at the top
of the screen, so that the user may choose by pressing
either the " X" key for X a.xis rotation, the "Y" key for
Y axis rotation,or the " Z" for Z a.xis rotation. Once the
choice is made the program will enter into that specific
rotation function. Once entered into one of three rotation
functions another menu will be displayed. That menu will
consist of a series of numbers that represent different
angles that the object will be rotated on. The " F9" and
" FlO" keys will activate a separate menu cursor that will
rotate the object in real time. This effect will allow the
designer to make a visual choice. If the designer already
knows which angle is to be used the cursor can be place on
the first letter of the menu. This will activate a query
35
function that will receive any angle that is desired. Each
axis rotation function can be accessed from the other
simply by pressing the letters X, Y or Z. This will
eliminate the need to return back to the main rotation
function. Also, translation and grid space commands are
available within each function. This will give the user
the ability to create models freely that would require
multiple rotations of a single element, such as a spiral
stairway. In order to exit back to the main menu the the
"Ksc" should be pressed.
Once a rotation values been set they are stored in a
variable, each axes has its own variable. If the variable
is greater than zero then the rotation commands will be
written with the solid object it defines, and then another
command will also be written to rotate the modeling matrix
back to zero. Here is an example block rotated at 45
degrees on the Z- axis
MD TRAN MDORG MD ROTZ LOCATE PSOLID MDROTZ
0.0, 0.0, 0.0 0.0, 0.0, 0.0 45 0.0, 0.0, 0.0 4, 10.0, 70.0, 50.0--315

37
FACETING FUNCTION:
The Faceting Function has the ability to draw curved
surfaces or solids to a greater or lesser precision. In
this graphic system curved and circular objects are drawn
with a series of lines or planes that represent that
object; therefore, a round column can be represented as a
six sided column in gouraud shading and may be drawn very
quickly with little accuracy, or may be drawn slowly
having sixty sides with a greater amount of accuracy.
Another useful aspect of the Faceting function is the
ability to draw an eight, six or twelve sided column just
by adjusting the faceting angle. If this is the desired
outcome then the Constant Shading Function should be used.
The Faceting Function and shading functions work together
to create different attributes associated with the manner
in which the object is drawn. The Faceting Function is
activated by the modeling menu branch, and access is
achieved by pressing the "m" key, then the "f" key. Once
the faceting function has been entered it will present its
own menu, that menu consist of a series of numbers that
represent the faceting angle. If the "F9'' or "FlO" keys
are pressed they activate a menu cursor that will select
the desired angle.
38
The command for faceting is Dispat 4 num, num may be
any number from 0 ... 7. The higher the number the more
accurate the model and the slower the drawing speed. The
number will also give a particular number of sides to a
circular edge. They are as follows
NUM ANGLE NUMBER OF SIDES TO CIRCULAR EDGE
0 90 4 1 60 6 2 45 8 3 30 12 4 20 18 5 15 24 6 10 36 7 6 60
An example command list for an eight sided column
would be :
DISPAT 4, 2 DISPAT O, 0 LOCATE 0.0, 0.0, 0.0 PSOLID 0, 35.0, 130.0
sets to eight sided circular edge sets to constant shade
locates solid at the origin -- defines solid as a column

GOURAUD SHADING FUNCTION:
The Gouraud Shading function is represented by the
abbreviation GSHADE. This type of shading performs a
blending of all the surface planes so that the object has
a very smooth surface appearance. The Shading Function is
very useful in creating round smooth surfaces. It is also
used in conjunction with the Faceting Function when
drawing time is important, example: a sphere drawn with
gouraud shading at a faceting of fifteen degrees will
appear smooth and round, and may be drawn quickly. At the
same time a sphere drawn at six degree facets will have a
more accurate spherical shape, but it will take over twice
the amount of time to draw. When a model that has several
hundred circular objects in it is being redrawn, it may be
an advantage to use a greater faceting angle in the design
development stage and to use a higher accuracy image for
presentation purposes. In order to activate gouraud
shading the user must first enter into the Modeling Menu
then press the "g" key, this will automatically set the
shading mode and all other objects will be drawn in
gouraud shading until a change is made.
The Gouraud shading command is DISPAT 0 1. Once placed
in the Command list all following objects will be drawn in
Gouraud Shading.

CONSTANT SHADING :
The Constant Shading or Angular Shading function is
represented by the Abbreviation ASHADE. This type of
shading shades each surface patch separately, with this
shading technique all angles facets are made visible. By
using Constant Shading the sphere primitive can represent
a tetrahedron, octohedron, decahedron, dodecahedron and
more simply by adjusting the faceting angle. Cones,
columns, rings and tubes can also be faceted to make a
wide range of primitives that have four to sixty-four
equal sides. In order to activate constant shading the
user must first enter into the Modeling Menu by pressing
the ''m.. key then press the "a" key.
The Constant shading command is DISPAT 0 0. Once
placed in the Command list all following objects will be
drawn in Constant Shading.

TRANSLUCENCY FUNCTION
The translucency function transforms a solid opaque
object into one that has a different level of
translucency. There are five levels of translucency that
may be activated, they are : 100% opaque, 50% opaque, 25%
opaque and 12.5% opaque. Each level then has different
patterns of dithering that the translucency mask is
applied to. The 50% level is the simplest and has two
levels. Below is a diagram showing two complementary
masks on a 2 X 2 pixel area of an image.*
~ ~ LEVEL 1
~ ~ LEVEL 2
0 = DO NOT CHANGE
X = DRAW THE PIXEL
If level 1 is applied then a 50~ translucent object is
drawn. Level 2 will also draw a 50% mask and is the
compliment of level 1. The advantage to this is that the
two can then be combined. For example if a red translucent
object is in front of a yellow translucent object, the
viewer would see orange where the two overlap. If both use
level 1 then one would mask the other and the first drawn
object would only be seen.
45
The 25% mask works on the same method, but has four
different patterns, they are diagramed as follows:
0 = PIXEL IS NOT DRAWN
LKVKL 3
x 0 x 0 x 0 0 0 0 0
I 0 I 0 x 0 0 0 0 0

46
The 25% mask allows four translucent objects to be seen
overlapping each other. One pixel is drawn for every 2x2
pixel area. The values are from level 3-6.
The 12.5% translucency mask values are from 7-14 this
mask allows eight different planes to viewed through each
other, two pixels are drawn for every 4 x 4 pixel area.
LEVEL 7 - 14
the number level selected will draw the
corresponding pixel number.
7 12 14 9 7 12 14 9

14 9 7 12 14 9 7 12
10 13 11 8 10 13 11 8
47
Another advantage to translucency is that the color
table can be increased by blending colors. The 50% mask
allows the blending of two colors in the color table while
the 25% mask would allow four colors to be blended while
the 12.5% eight.
In order to activate this command the modeling menu
must first be entered by pressing "m" then by pressing the
"t" key the translucency menu will be shown. The different
levels of translucency will be displayed at the top of the
screen.
TRANSL 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14
By pressing the "F9" and "FlO" keys the menu cursor
will move to the desired level, or by pressing the desired
"num" key, once selected the "space" bar will activate
that command. The translucency index will not change
unless another selection is made.
The COMMAND LIST format for translucency is as
follows:

SCALING FUNCTION :
The scale functions include scaling on the X, Y and Z
axis. Kach can be performed all at once or separately.
When all three axes are scaled the object will retain the
same proportions as the original object. If one axis such
as the X axis is scaled then only the dimensions on that
axis will be scaled. This is useful in creating new
primitives, example: a sphere or a column can be scaled on
one axis to become more elliptical in cross section.
Scaling differs from the Dimension Function in that the
everything on the axis being scaled is changed after the
function is activated, while the dimension function acts
only on the primitive being drawn. The scaling values
will remain on until the function ls called again.
The Scale Function is activated by entering into the
Modeling Menu by pressing "m" the by pressing "s". Once in
the function a scaling menu will be displayed
SCALE XYZ AXIS X AXIS Y AXIS Z AXIS
Once the selection is made by either the menu cursor or by
pressing the highlighted key, a query will ask the user
for the scaling value.
The COMM.AND LIST format is as follows: MDSCAL 0.5, 0.5, 0.5
This command will scale the X, Y and Z axis by 0.5.

CENTERING FUNCTION
The Centering function acts as a reset button it will
set Scaling and Rotation values to there default values.
It will also set the cursor back to the origin. The
command MDIDEN is used to reset the modeling matrix. Once
it is called all translation, rotation and scaling value
are set to their default values.
ORIGIN SET
The Origin Set Function is closely associated with
rotation and scaling functions. This function allows the
User to set a particular point in which to rotate an
object about, or be able rotate an object on end. Without
this function objects will only be able rotate around
there centroid; however, by being able to move the point
of rotation, complex composite solids may be constructed
quite easily. An excellent example would again be the
construction of a spiral stairway. The same object may be
rotated around the same Y axis while only increasing the Y
value.In order to activate MDORG press the "o" key, this
will save the current location, and enter into access to
the Translation functions. The user may then move the
cursor to desired point. Once this is accomplished the
"space" bar should be pressed, this will record the new
point and the difference between the two points. An
example of a rotated block on end is as follows:

VIEWPORT FUNCTIONS
The viewport function include those functions that
allow viewing transformations, these function do not alter
the model in any way, they only allow the viewer to have
different view points of the model. The program will allow
the user to view the model from any angle, from an outer
or inner perspective. This will allow a walk through
perspective of a model. The functions that are included
are as follows:
ROTATE X ROTATE Y ROTATE Z DISTANCE VIEWPOINT --WINDOW -----
rotates the model view around the X axis rotates the model view around the Y axis rotates the model view around the Z axis determines the distance from the view point determines the point that is being viewed zoom for orthographic projections
These functions work within the file SKTUP.D if any
changes are made to the viewpoint of the model the entire
Command List most be run with the new changes in the setup
file. Kach function will create a Command in the SKTUP.D
file, They are as follows:

COLOR FUNCTION
The Color Functions are a set of functions that
control the color of an object. They are accessed through
the Color Menu Function which is activated by pressing the
"c" key. Once activated it will display the color menu.
WHITE RED YELLOW GREEN BLUE SKY PURPLE
To select the desired color the user then may press
the first letter of that color. All objects drawn after
the selection will be drawn in that color until another
selection is made. After the selection has been made the
color command COLOR num is added to the command list.
Once added to the command list the object will be
recreated in the selected color. Each color represent 32
shades of that color. This will give a very realistic
shading of an object. The maximum colors available on the
screen are 256, however this can be increased by using the
transparency function and blend two to four colors
together. Kach color is coded with a number which
activates the graphics board to that specific color. The
list is as follows:

REMOVE FUNCTION:
The Remove Function purpose is to allow the user to
delete unwanted objects from the screen. The is a very
useful function especially in the design stage when many
changes may be made. The Remove Function is activated by
pressing the "r" key. Once the key is pressed the cursor
will take the shape of a block, this block may then be
move to any location on the screen. When the "r" key is
pressed a second time all objects that are inside of the
block will be deleted from the screen and the command
list. In
capability
order to provide a more accurate deleting
the blocks dimensions may be changed by using
the Dimension Function. The function works simply by
comparing the coordinates of the deleting block to that of
the objects on the screen. Those objects that are within
the blocks boundaries will not be redrawn to the screen.
All curved shapes such as spheres and cones will be given
a rectilinear boundary definition to speed up
calculations. For even faster removal the function may be
set to locate only the centroid or closest object to the
cursor location. An example of boundary definition
removal is as follows:

WINDOW FUNCTIONS :
The Window Functions are a set of functions that allow
the user to move from orthographic projections to
perspective views, also is the ability to set the number
of viewing windows from one to three. The purpose of these
functions is to give the user multiple views of a model.
When in the design stage it is very critical that the
designer be able to view an object from several
perspectives. While in a perspective view it is nearly
impossible to determine the space relationship between two
objects without a undistorted form of measurement such as
a plan or elevation. The multiple window does just that,
it gives a plan, elevation and a perspective view of the
model. A cursor is visible in all three window
simultaneously.
The function are activated by pressing the "w" key,
once this is done the Window Menu will be displayed at the
top of the screen.

FILE FUNCTIONS
The Filing Functions are the designers way of storing
Command Lists of models. The functions consist of two, one
to create a new file and one to display an existing file.
To activate these functions the user must press the "f"
key. Once this is done the menu will query the user, if a
new file will be created or an existing file should be
displayed. A "c" or "r" key should be pressed. After a key
is selected another query will ask for a name. If a file
list is needed press the "f" key, all existing work files
will be presented with a brief description. The file names
may also be filed with a suffix code and put into separate
categories. The Create new file works simply by writing
the existing COMMAND.D List to the newly created file. The
receive function is very similar replaces the existing
COMMAND.D file with the selected file.

CONCLUSIONS :
After undertaking such an extensive project a great
amount of learning and experience has taken place. One of
the biggest lessons has been, that while working with the
computer a whole new world has begun to unfold. The
computer has become the teacher, a very demanding one that
demands a clear structured way of thinking. The computer
language itself is a part of this structure. The structure
of the language itself seems to open up new ways of
thinking, and a greater awareness of the working process
of our own mind. After all it is man communicating to a
machine, and man creating the structure in which to
communicate.
This last year has been my first exposure to
computers and their capabilities, and my conclusions are
quite simple, its simply one of the tools of the future
that will be in almost every working environment,
especially in the designers work space. Those of us who
choose not to be involved with computer, are actually
selecting a very limited future.
If I look at where this program will be in the future
I would predict that there will be libraries of
subroutines available, which this program could utilize,
examples would be complex light shading, and reflection of
67
surfaces. Ray tracing routines which are done on super
computers will be more widely available and a program such
as this one would be able to utilize such routines. The
menu structure and how they accessed be comes a very
important issue, because the menus structure may greatly
effect the design process. Future revisions will examine
and refine the relationship between design process and the
program interface. This program is now dependent on a
very sophisticated graphics board, I selected this option
because at present solid modeling on standard systems is
much too slow. Most of the design work needs to done in
wire-frame, then transferred into shaded objects; However,
with the use of more powerful hardware solid modeling
becomes possible. In a few years this will chanF.e,
personal computer speeds will go up and prices should come
down. Already in one year, computing speed has been
greatly improved, and in a few more years personal
computers may have the speed of a supercomputer. The main
hardware improvements may probably always be speed, memory
and resolution. The Software improvements will focus on
what this thesis has investigated, how we are able to
68
communicate with the computer in terms of design. I
believe this thesis has dealt with many design issues, and
the end result is a program that may be used to create a
3D model in a way that the designer may understand;
however, I must add this is just the beginning. This
thesis is more an expression and investigation of a design
process rather than an end product.
