Vector animation is a term used to refer to animation in which the art or motion is controlled by vectors rather than pixels. Vector animation often allows cleaner, smoother animation because images are displayed and resized using mathematical values instead of stored pixel values.
In vector graphics, the file that results from a graphic artist's work is created and saved as a sequence of vector statements. For example, instead of containing a bit in the file for each bit of a line drawing, a vector graphic file describes a series of points to be connected. One result is a much smaller file.
