Computer graphics: genera ating 2D images of a 3D
world represented in a comp

Main tasks:
modeling: (shape) creating an representing the geometry
nd
of objects in the 3D world
rendering: (light, perspective) generating 2D images of the
objects
animation: (movement) describing how objects change in
time
