3. Vector images:
Drawing elements or objects such as lines, rectangles, circles and so on to create an images are based on Vector images.
Animation is the process displaying still images so quickly so that they give the impression of continuous movement. Path animation involves moving an object on a screen that has a constant background e g. a cartoon character may move across the screen regardless of any change in the background or the character.
