U n it 19 Graphics and design 1 Warm-up 1 Look at the pictures above which were all created on computer. Which ones are three-dimensional? Are there any advantages of creating three-dimensional images?
2 From the pictures, can you suggest which people might use computer graphics professionally? What would they use them for?
3 Can you think of other professionals who use computer graphics? How do they use them?
2 Reading Read through the text and find the answers to these questions.
1 What are 'computer graphics'?
2 What do the acronyms 'CAD', 'CAE', 'CAM' stand for?
3 What are the benefits of using computer graphics in the car industry?
4 What are the benefits of using graphics in business?
5 What is 'computer animation?'
Computer graphics Computer graphics are pictures and drawings produced by computer. A graphics program interprets the input provided by the user and transforms it into images that can be displayed on the screen, printed on paper or transferred to microfilm. In the process the computer uses hundreds of mathematical formulas to convert the bits of data into precise shapes and colours. Graphics can be developed for a variety of uses including presentations, desktop publishing, illustrations, architectural designs and detailed engineering drawings.
Mechanical engineers use sophisticated programs for applications in computer-aided design and computer-aided manufacturing. Let us take, for example, the car industry. CAD software is used to develop, model and test car designs before the actual parts are made. This can save a lot of time and money.
Computers are also used to present data in a more understandable form: electrical engineers use computer graphics to design circuits and people in business can present information visually to clients in graphs and diagrams. These are much more effective ways of communicating than lists of figures or long explanations.
Today, three-dimensional graphics, along with colour and animation are essential for such applications as fine art, graphic design, computer-aided engineering and academic research. Computer animation is the process of creating objects and pictures which move across the screen; it is used by scientists and engineers to analyse problems. With the appropriate software they can study the structure of objects and how it is affected by particular changes.
Basically, computer graphics help users to understand complex information quickly by presenting it in a clear visual form.
К^ЛRead the passage below and complete it. Then listen and check your answers. A basic tool palette A graphics (1) p...................................... is the software that enables you to draw and
manipulate objects on a computer. Each graphics package has its own facilities, plus a wide range of basic drawing and (2) p...................................... tools. The
collection of tools in a package is known as a palette.
The basic shapes which are used to make (3) g...................................... objects are
called 'primitives'. These are usually geometric, such as lines between two points, arcs,
(4) c....................................... polygons, ellipses and even text. You can
choose both the primitive you want and where it should go on the screen.
Moreover, you can specify the (5) 'a......................................' of each primitive, such
as its colour, (6) l...................................... type, fill area, interior style and so on.
(7) i..................................... in a menu. To use one you activate it, by
(8) c...................................... on it. For example, if you want to draw a rectangle, you
activate the rectangle tool and the pop-up options allow you to choose the origin of the rectangle (using the insertion point as its centre or corner) and the possibility of
(9) d....................................... a rectangle with rounded corners.
В Look at the functions represented by the icons in the tool palette below and match them \vith the definitions on the right. Tools Definitions
a) This is used to scale the view. Similar to the command 'Zoom in/out'.
b) This is used to delete the part of the picture you drag it over. It is known as 'Eraser'.
c) This is used to type text.
d) This draws a straight line between two points.
e) This is a paintbrush used to add colour and patterns. It often comes in different shapes.
f) This is used to draw polygons with irregular sides.
g) This is used to draw thin, free-form lines.
h) These are used to select text and images.
i) This draws an arc, or part of a circle.
j) This draws curved, free-form shapes.
k) This is used to draw a circle with two foci, known as an ellipse.
1) These two are used to draw all kinds of rectangles, even ones with rounded corners.
m)This is used to draw a circle.
n) This is used to draw polygons with equal sides.
4 More about graphics A Graphics programs have several options that work in conjunction •with the tools menu to enable the user to manipulate and change pictures.
Look at the facilities in column A and match them with the definitions in column B. В
1 The patterns menu a) Turning an image round.
2 Scaling b) A tool which lets you scale the 'view' of a
picture and edit a small portion of it as if you were working under a magnifying glass. It is very useful for doing detailed work as you can edit the picture one dot at a time.
3 Rotating c) Making the object larger or smaller in any
of the horizontal, vertical or depth directions.
4 Inverting d) A shading technique where two different
colours are placed next to each other; the human eye blends the colours to form a third one. It is also used to show shading in black and white.
6 Slanting f) Reversing the colour of the dots in the
selected part of a picture, so that white dots become black and black dots become white.
7 Black-and-white dithering g) Inclining an object to an oblique position.
В Look at the pictures and label them -with the facility that has been used to change the original. 5 Language work: Gerunds (-ing nouns) A Read the passage below. Underline the gerunds and decide -whether they function as the subject, the subject complement, the object of a verb, or the object of a preposition. You cannot create a picture simply by specifying primitives. Instead, you must specify the primitives and their attributes, then transform them by specifying where and how you want them placed on the screen so they create your picture. Transformation means moving or otherwise manipulating the object by translating, rotating and scaling the object.

What is'desktop publishing'? 'Desktop publishing' refers to the use of personal computers to design, implement and publish books, newsletters, magazines and other printed pieces. Desktop publishing is really a combination of a few different processes including word processors, graphic design, information design, output and pre-press technologies, and sometimes image manipulation. There are also many applications that support these processes, including font creation applications (that allow users to design and create their own typefaces, called fonts) and type manipulation applications (that allow users to modify text in visually creative ways).
Desktop publishing centres around a layout application. A layout application is used to import text from word processing applications, graphics from paint and drawing applications and images from scanning or image manipulation applications, and to combine and arrange them all on a page. They typically can bring in or import many different types of files. It is this ability to manipulate so many different items and control how they are used that makes layout software so popular and useful. This software is usually the last stop before a document is printed. Once composed and designed, these files can be printed onto film by high quality devices, called image- setters, and printed on a traditional printing press.
Because imagesetters are expensive devices, most people cannot afford to buy their own. There are, however, companies called service bureaus that specialize in printing other people's files on imagesetters, just like copy stores make copiers available to others. Service bureaus can offer a variety of equipment and services. Some offer imageset output, laser printer output, colour laser printer output and even slide or film recorder output. In addition, some have colour scanning equipment.

3 Word building Look at the box on the right which lists ways of forming new words in English. Then in pairs, look at these words and decide: - which process of word formation has been applied.
- what part of speech each word is.
- \vhere the stress falls in each word. Underline the stressed syllable(s). 1 upgrade
New words are formed in three main ways in English:
a) adding a prefix to the base: print —> reprint
b) adding a suffix to the base: print —»printer
2 Conversion, i.e. assigning one class to another: print v -н> print n.
3 Compounding, i.e. adding one base to another: finger + print -» fingerprint.
