ne ofthe greatest challenges

for people to learn is todraw in correct perspective.

Teachers have struggled for years tofind methods to teach students todraw correct perspective rapidly andeasily. I have found a method thatworks well and is easy to learn. It willwork every time. Even if you have noartistic training, this method willenable you to create drawings withaccurate perspective.

The Box MethodThe box method involves a box orcube. If you can draw a two-dimen-sional square correctl¡ you then can

easily draw a box. If you can draw a

box in accurate perspective, you can

draw an¡hing accurately and in per-spectlve.

It sounds simple, doesn't it? It is sim-ple. It will take some practice. It willtake time to understand what is hap-pening.You will have to practice those

things mentioned in this book. But, ifyou do practice the method, you willfind it is really quite easy.

On the following page is a box that

you must cut out. Do not be afraid-this book is meant to be used! Cut outthat page and cut the figure to assem-

ble the box as shown. You will need to

tape or paste the edges together tohold the final box form in place. You

will use this box to look at and draw

in the upcoming exercises throughoutthis chapter.

Once you have assembled Your box,

you need to find a piece of clear glass

or Plexiglas or vinyl (like a clear

report cover) and a felt tip pen that

you can use to draw on Your clear

piece of material.

This ls ç-hat the æembledbox should look like.

Take your box and set it uP behind

your clear material. Then hold the

clear sheet stationary while you trace

the box on it. Hold everything very

steady. Trace the box exactly as you

see it. Keep your eye in one steadY

position, the box stead¡ and the clear

sheet still. if you don't move anY ofthem, then you can draw the box incorrect perspectlve.

Hint: Don t use both eYes. Shut one

eye. If you use both eyes, you will get

a double image making it difficult todraw.

If you move the box up or down or ifyou move up or down, you will see

different views, or planes, of the toP

and bottom of the box. The view ofthe surface that you see changes as

your eye level changes. This eye level

line is called the horizon line' Thehorizon line is always level and isalways at the level of your eye. Thus,

the view of the top and bottom of the

box changes as you move your eye

level or horizon line.

One-Point PerspectiveOne-point perspective is viewed whenparallel lines appear to converge anddisappear at one point on the horizon.If you hold the box directly in front ofyour eye, you will see one-point per-spective. If you have ever looked downa railroad track while standing in themiddle of the track, you have noticedthat the tracks seem to converge at

one point far in the distance and even-

tually disappear. This is anotherexample of one-point perspective.

There are three different kinds oflines-vertical, horizontal, and per-spective-in perspective drawing.Vertical lines run up and down. Some

are straight and some run angled.Horizontal lines run from side to side

like the horizon. Perspective linesconverge at some point on the hori-zon line. One-point perspectiveincludes all three kinds of lines.

As you draw the box, the surface thatyou draw on (the clear material) is

called a picture plane. The pictureplane is not limited to tracing theimage through clear material; the pic-ture plane could also be the paper youuse as you draw the box.

Chapterl r Perspective 19

Two-Point PerspectiveTwo-point perspective is viewed when,from a given edge, parallel lines con-verge at two single points on the hori-zon line at opposite sides of yourpâper. This perspective is demonstrat-ed by turning the box you just made

so that you are looking at an edge ofthat box. From that edge the sides ofthe box seem to get smaller as theymove away from the eye. The sides

appear to get smaller until they vanishat two different points on the horizonline.

In the examples on the previous page

and below, notice how the edges onthe newspaper machine and on thecereal box appear to get smaller as

they move farther away from you.

Three-Point PerspectiveThree-point perspective is viewedwhen lines appear to converge at threegiven points either to the sides of thepicture plane or at the top or bottomofthe page, depending on where youreye level line is.

Look at the corner of the building inthe following image. As the sides ofthe building go away from you, thetwo parallel edges create lines that willdisappear at a point on the horizonline. As you look up at the buildingyou will notice that the vertical linesthat go up appear to get closer and

closer at the top so that they wouldeventually disappear at a point highabove the building.

Key Principles of PerspectiveThe key principles to remember whendrawing boxes in perspective are:

1. Perspective lines converge at avanishing point.

2. The horizon line is alwavs hori-zonfal.

Vanishing Poinrshould be behind the box

VertÍcaILinesshould bevertical

Chapter 1 r Perspective

3. The nearest angle is 90o orgreater.

4. The sides ofa cube are propor-tional to a square.

Some common errors occur whenyou learn to draw cubes. A few towatch for are:

Exercise 1.1

You need to develop a critical eye so

that you can easily see if a cube is

drawn in correct perspective. Here are

some lines that are three sides of a

square. The fourth side is missing.

You draw in the fourth line so thatthese squares show accurate perspec-

tive. (Hint: Slide a straight edge alonguntil the square appears visually cor-rect to you, and then draw the line.)

The next image depicts many differ-ent cubes within a circle with a hori-zon line. All of the cubes are drawn intwo-point perspective. The cubes

above and below the horizon linebegin to distort because of the per-spective drawing. Whenever you drawthings in perspective, it is helpful toimagine that you are drawing withinthe limits of a circle. If you drawbeyond that imaginary circle, then the

cubes begin to appear so distortedthat they won't seem real.

Drawing One-Point Boxes

You have three kinds of lines in one-point perspective-vertical lines, hor-izontal lines, and perspective lines. Ifyou seem to have trouble drawingthings correctly, draw the box as

though it were transparent so that youcan see the hidden sides, edges, andcorners. Then erase the hidden lines,

once you have everything drawn cor-rectl¡ thus leaving a solid box.

In one-point perspective, the fartheraway from the central vanishingpoint, the closer to the outer edge tothe circle, the more distortion. Thisdistortion that occurs when you nearthe outer limits of the circle is morepronounced with one-point perspec-

tive than with tr¡¡o- and three-pointperspective.

ffi*dBoxes outside of circleapper dlstorted

Drawing Two-Point Boxes

Drawing in two-point perspective is

the easiest of all perspective drawingfor most people. You have only twokinds of lines-perspective lines orvertical lines. If you have troubledrawing things correctl¡ draw thebox as though it were transparent so

that you can see the hidden sides,

edges, and corners. Then erase thehidden lines after you have drawneverything correctly.

Drawing Three-Point Boxes

There is only one kind of line inthree-point perspective-perspectivelines. If you have difficulty drawingthree-point perspective boxes correct-ly, draw the box as though it weretransparent so that you can see thehidden sides, edges, and corners. Afteryou have everything drawn correctl¡erase the hidden lines.

The boxes inside the following circlelook like you are looking down onthem. To reYerse the point of view,simply turn this book upside down.The boxes will then look like you are

beneath them.

Dividing a SquareAs shown in the following example,diagonal lines drawn from corner tocorner of a square cross in the exact

middle of that square. A line drawnfrom the middle of the square to thevanishing point bisects the edge at

midpoint. If you draw a line from thecorner through the midpoint of theside, this line will cross the bottomline of the square giving you the loca-tion of the far corner of the nextsquare. This principle is used to helpdivide a square into equal segments orto enlarge a square in equal segments.

Below is a square drawn in perspective.You are above the square looking down on it.Using the dlagonal to diUde the square appl¡esin perspective also.

2nd Divislon

The lower half of the next exampledemonstrates a square drawn in per-spective. In this drawing, you are

into quarters. You will need to drawthe hidden edges (sides of cubes away

from you that you don't see) of the

cubes in order to know where todivide them.

Units of MeasurementA cube can act as a standard of mea-

surement. The cubes shown here are

all the same size, but they appear to be

different sizes because of the sur-roundings-the woman, the tiny per-son, the man, the shoe. These differ-ent cubes can represent different unitsof measurement such as one inch, one

foot, one mile, and so on depending

on the surroundings that create scale.

The following box is divided intoequal units. The box measures 10

units tall x 5 units wide x l0 unitsdeep. If the units were not specified,

you could still determine the propor-tion because the box is half as wide as

it is tall.

Draw this cubeas5x5x10.

Draw this cubeasl0xl0x5.

Exercise 1.7

Chapter 1 r Perspective

Adding SquaresThe same principle of using diagonallines to find the exact middle of the

sides of a box also enables you to drawmore than one square in perspective.

Begin by finding the exact middle ofthe square, and then extend a linefrom the corner through the middleof the far side. Where that line inter-sects, the bottom perspective lineshows you the length of the nextsquare in perspective, as shown in thefollowing example.

Squares drawn in perspective appear

to diminish in size. You can find the

correct rate that they diminish bydrawing the diagonal lines to find the

center of the far edge of the square.

Draw another diagonal line from the

corner of the square directly throughthe midpoint of the edge and down towhere it finds the bottom corner ofthe next square.

Multiplying Squares

These squares drawn in perspective

easily can become cubes. The same

principles that apply to the square

apply to the cube or box. Iust stack

cubes on top ofone another or next toone another to draw larger, morecomplicated objects.

The me method ttEt works ln two dimenslons will alswork in thre dlmensions.

To draw other squares, cubes, or boxes

in correct proportion, first use the

diagonal to find the center of the side.

Draw a line from the center of the side

to the vanishing point-this bisects

the far side exactly in half. Draw a linefrom the corner through the center ofthe far side to where it intersects withthe bottom perspective line of the

box. This intersection between the

Chapterl r Perspective 33

diagonal through the side to the bot-tom gives you the size of the next

square or box in succession.

Exercise 1.9

Use tracing paper to draw the cube

shown here. Draw 3 cubes in every

direction-in front, behind, above,

below, to the right, and to the left-from the original cube.

i

Page 21: rapid-viz_15-53

34 Rapid Viz ¡ Third Edition

A¡other principle that you will finduseful when multiplying squares isthat diagonal lines converge at a singlevanishing point. The following illus-tration demonstrates how this works.The boxes must be equal in size(squares in this example), and thesides of the box must be parallel.

You can apply this principle to drawobjects in perspective. If you candetermine diagonal lines of boxes, youcan then find the far corner and canadd more boxes quickly. The followingcube is taken from the previousexample of many cubes drawn in

Adding Boxes VerticallyParallel lines (sides of a flat surface

that sets at an angle such as a rooftopor open box lid) converge at a singlepoint. You could use this knowledgeto help you draw the rooftop of a

building. The lines that form the side

of that roof, when extended, converge

Rapid Viz r Third Edition

at a vanishing point directly above thevanishing point on the horizon line.This point above the horizon line is

called a trace.You will find it useful toknow that these lines do converge at a

point above or below the vanishingpoint on the horizon line.

So far we have concentrated oncubes-boxes with equally sized sides.

However, you also need to be able todraw different sized boxes. You can

create odd sized boxes by butting twoor more cubes together, as shown inthe following examples of assorted

box sizes.

Exercise 1 .12

Practice applying the principlesyoúve learned by creating odd sized

boxes. Strive to draw accurate per-spective without having to draw all ofthe hidden sides, vanishing points,and converging lines. You shouldbecome so familiar with how thingsshould look when drawn correctlythat you can do it right the first time.

Different ViewsNow that you have learned how todraw boxes and squares, you can take

it to the next level by using those boxes

to create different images. Whendrawing buildings for architecture,you show different views of the pro-posed building-front view, side view,

and top view. These views are as if youplaced your building within a glass

box and then traced the appropriateview. If you look down, directly on topof your box, you see the top view ofthe building. If you look at one side,

you see the side view, and so on.

You need to learn how to convert

those three different views into a

three-dimensional object. Rememberthat these different views are as

though you were peeling away the

sides of a box with an object drawn onthe sides of that box. They are flatviews of a three-dimensional object.

Place the object inside a transparentbox. The views are drawn on the sides

of the box, and then the box is

unfolded.

Drawing a ChairIf you can draw a cube, then you can

apply the cube method to draw otherobjects. For example, I created a chairby beginning first with a cube and

then erasing the lines of the cube so

that all that remains is the chair.

Exercise 1.17

Draw 5 chairs using the cube tech-

nique. Begin by completing the 2

drawings started in the followingexample, and then create 3 of yourown from scratch.

Drawing a BuildingDrawing the exterior of a building is

accomplished by using the same prin-ciple as drawing previous objects. Youstack different squares or cubes nextto one another to form a basic build-ing. Use the principles of diagonal

lines to find how to correctly stackyour cubes in perspective. Then createthe different angles, views, and sur-faces for the building.

The following example is a building Iconstructed using cubes to help draw

the final view of that building. It wasdone simply by extending cubes. Westarted with one cube and thenextended cubes in different directionsto get the other sides and surfaces ofthe building.
