The
Anatomy of a Vector Illustration
Part One
Illustrations created in all major vector drawing programs
have a definite anatomy and share a common pattern. Whether
you use Deneba Canvas™, Adobe® Illustrator®, CorelDRAW
or Macromedia® FreeHand® you will find that this pattern exists
even though each program may define the parts differently.
The purpose of this section of the web site is to take apart
a vector drawing so you can see how it is put together and
able to understand it. In the illustration section is a table
of equivalent terminology to better help you translate
the terms from one application to another. This will clarify
the subject and make it less confusing. You will not be bound
to a single application once this becomes clear to you.
The pattern of vector illustrations is best viewed or
represented as a hierarchy or "tree". The illustration itself
would be at the top and its various parts would descend below
it:
An ILLUSTRATION is composed of vector
OBJECTS each having one or more
PATHS which are composed of
LINE SEGMENTS having
ANCHOR POINTS at each end
Illustration:
Objects:
Paths:
Line Segments and Anchor Points:
In the diagram above the OBJECT shown is composed of a single
closed PATH composed of 19 LINE SEGMENTS and 19 ANCHOR POINTS.
Notice the curved line on the bottom. It is composed of 2 separate
line segments even though it appears to be one continuous smooth
line.
