Transformations in Animations

All animations are made up of a series of different types of transformations. If an animator wants to move a character or object left/right or up/down all they have to do is reflect the object/character in respect to the x-axis or y-axis. An example of rotations and dilations is in animation is in the Spider-Man animated series.  In the cartoon, as he is flying, he rotates a certain number of degrees through the air. Then if he is going away from the camera he dilates a negative amount.
