An overview of the fundamental concepts and techniques in computer graphics, including graphics primitives, scan conversion algorithms, polygon windowing and clipping, color models, lighting and shading, and curves and fractals. It covers the basic terminologies, mathematical foundations, and programming aspects of computer graphics, with a focus on the opengl library. Display devices, graphics modes, and various input devices like mouse and light pen. It also introduces the concept of display file and display file interpreter, which are crucial for understanding the rendering process. The document aims to equip students with the necessary knowledge and skills to develop elementary computer graphics applications.

Display Devices
- The display device is an
- output device used to represent the information in the form of images (visual form). Display systems are mostly called a video monitor or Video display unit (VDU).
- Display devices are designed to model, display, view, or display information. The purpose of display technology is to simplify information sharing.
- Today, the demand for high-quality displays is increasing.
- There are some display devices given below:
- Cathode-Ray Tube(CRT)
- Color CRT Monitor
- Liquid crystal display(LCD)
- Light Emitting Diode(LED)
- Direct View Storage Tubes(DVST)
