>> a and d are three-dimensional; b and c are two-dimensional

2. What are the advantages of creating 3-D images?

>>3-D images represent objects more accurately; in graphs, they also illustrate different quantities more clearly.

3. Which types of professionals might use the computer graphics(3-D)?

>> a. Business people; b. Archtects; c. Carographers(map makers); d. Car engineer

4. Who else uses computer in their job? How do you use them?

Graphics (1)…design software……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)…drawing and editing……tool. The collection of tools in a package is known as palette.

The various tool in the palette usually appear together as pop-up(7)……menus………in a menu. To use one you activate it by (8)……clicking…on it. For example if you want to draw a rectangle, you activate the rectangle tool and the pop-up options allow you (9)…to…… choose the origin of the rectangle (using the insertion point as its centre or corner) and the possibility of (10) …creating… a rectangle with rounded corner.
