Computer Generated Visual Media

Two main paradigms in computer generated imagery : The simplest is 2D computer graphics it reflects how you must use pencil and a piece of paper. The image is on the computer screen and the instrument you might use is mouse drawn with a pencil, paintbrush and pen.  The second type is 3D computer graphic, screen becomes a window into a virtual environment ( Setting that can replicate physical existence in places in the real world, as well as in fantasy worlds)
