Vector Art
is a type of digital art that revolves around the creation of images
(often, by copying another non-vector image), with the use of vector
software.
In
computer drawing and animation, a shape may be created in one of two
ways, either as a raster image, or a vector image. Raster images work
by defining the image in terms of its absolute pixels, eg, a small
square might be defined as 4 rows of 4 pixels wide.
A
vector image would define a square by its essential coordinates. A
triangle, for instance, would be defined by the coordinates of its
three vertices. The advantage of this method is that it requires only
three pieces of information for three corners, rather than a piece of
information for every pixel contained therein.
Vectors
also have the advantage of being infinitely resizable, because the
coordinates can simply be increased or decreased in proportion. As
such, vector graphics often look cleaner and simpler.
Vector
Art is the art of drawing pictures using only vector graphics. Vector
Art is therefore infinitely resizable. It is also highly flexible and
compatible with many mediums, due to its vectorial nature.
Vector
Art often seems posterised, as individual pixels cannot be defined, and
therefore gradients cannot so easily be achieved. Vector Art therefore
often suffers the loss of a gradient, to be replaced with one solid
patch of colour.
Popular
vector programs include Adobe Illustrator, CorelDRAW, Macromedia Flash
and Freehand, Xara X, and Serif DrawPlus
