The
Anatomy of a Vector Illustration
Part Four - Summary |

|
The anatomy of a vector illustration has an exact, finite
pattern. There are only so many parts to it. It is summarized
below:
| 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 |
ANCHOR POINTS fall into two categories:
1. Those having CONTROL HANDLES and
2. Those having NO CONTROL HANDLES
Line segments with points having control handles are curved.
Line segments with points having no control handles are straight.
An ANCHOR POINT can have either:
1. ONE CONTROL HANDLE or
2. TWO CONTROL HANDLES
There is really only ONE handle per
SIDE of a point because points between consecutive line segments
are shared.
Points with both handles in line with each other are called
SMOOTH POINTS. All other points (except for the specialized
ones - "symmetrical node" and "connector point") are generally
referred to as CORNER POINTS.
Objects have stroke and fill properties. Stroke (or outline)
properties apply to the path of an object and fill properties
apply to the area enclosed by the path.
Objects may be:
1. Grouped or
2. Formed into Composite Paths or
3. Combined into new objects
Paths are either:
1. Open or
2. Closed
That's it!
The whole purpose of this was to drive home the point that
there is an anatomy to a vector illustration. It has an exact
pattern. It is finite. It is simple and all vector illustrations
from the simple to complex will reveal this pattern.
