2. COMPUTER GRAPHICS
 Geometric modeling: creating mathematical models
of 2D and 3D objects.
 – Rendering: producing images given these
models.
 – Animation: defining/representing time dependent
behavior of objects.

4. TYPES OF GRAPHICS
4
 A raster image is a
collection of dots called
pixels.
 Each pixel is a tiny
coloured square.
 When an image is scanned,
the image is converted to a
collection of pixels called a
raster image.
 Most images you see on
your computer screen are
raster graphics.
 Pictures found on the Web
and photos you import from
your digital camera are
raster graphics.
 A vector image is a
collection of connected lines
and curves that produce
objects.
 When creating a vector
image in a vector illustration
program, nodes or drawing
points are inserted and lines
and curves connect nodes
together.
 This is the same principle
as "connect the dots".
 Each node, line and curve is
defined in the drawing by
the graphics software by a
mathematical description.

6. COMPUTER-AIDED DESIGN
 Current Computer-Aided Design (CAD) is used in
the design of tools and machinery and in the
drafting and design of all types of buildings, from
small residential types (houses) to the largest
commercial and industrial structures (hospitals and
factories).
 It can also be used to design objects.

7. ADVANTAGES OF CAD
 Lower product development costs
 Greatly shortened design cycle.
 CAD enables designers to layout and develops
work on screen, print it out.
 It allows users to save it for future editing, saving
time on their drawings.

8. DESKTOP PUBLISHING
 Desktop Publishing is the merger of text with
graphics without using external services. Microsoft
word can be used as a desktop publishing package
through the use of word art, word graphics and
columns.

10. COMPONENTS OF DESKTOP PUBLISHING
 Document Composition software:
 The document composition software enables users
to design and make up the page or pages of a
document e.g. PageMaker
 Typefaces and fonts:
 A typeface is a set of characters that are of the
same type style (Times New Roman, Arial, Courier,
etc.).
