The first comptuer animation to win an academy award was Tin Toy in 1988. 2D Computer Animation Computer animation is often depicted as stop motion animation in which an object is drawn somewhere in a buffer out of view and then placed on the display to be seen. With this process repeated very rapidly in realtime the effect of motion is achieved. This effect is evident in cartoons and platform videogames like Super Mario Brothers where the scenery which represents the larger world in the videogame gradually goes by giving the appearance that the character is walking or running past the objects in the scene. Scaling is a transformation in which the object's size changes making it bigger or smaller.
Rotation is a transformation in which the object's orientation is shifted.
All of these transformations can be applied to 3D animation. In representing objects in the 3rd dimension, depth is used in which certain objects appear before other. One way of managing depth in 3D graphics is to apply what is known as the painters' algorithm to objects in a scene. The objects would be drawn in the scene in the same order that a painter would paint them. If an image of a person looking at a tree outside through a window was to be drawn, first the tree would be drawn then the wall with the window in it would be drawn followed by the person assuming that the colors would not mix together.
