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.
Vector graphics are images created from lines and directions. They differ from raster graphics in that they can easily scale to any size without pixelation, as the lines are redrawn whenever it is resized. Converting a raster, or pixel-based, image is tricky due to the inherent differences in the formats.
