1. Basics - Welcome to the world of computer graphics

Basic Concepts 1.1 graphics, the history and related disciplines

1. Computer Graphics

   Research on how to use a computer to show a discipline principles, methods and techniques of processing and graphics generation.

   Computer Graphics is the art or science of producing graphical images with the aid of computer.

   Input : Structure Data output : an image signal

2. Related disciplines

   Data Structure - Computer Graphics -> image signal

   Data Structure <- Computer Vision - image signal

3. Development History

   The first stage

   The second stage: Mature realistic computer graphics raster graphics budding

1.3 describes the function and structure of the system of FIG.

1. Functions of the computer graphics system

   Calculation stored interactive input output

2. Composition of computer graphics system

   Hardware : a display device a graphical input device storage media graphics output device (graphics display subsystem)

   Software : Game -> Game Engine -> graphics standards (OpenGL or DirectX) -> Graphics Driver [-> GPU -> memory] (hardware)
