Computer Graphics

Definition

Computer graphics is the art of generating, manipulating, and representing visual content (images, charts, animations, etc.) using computers and programming. It is composed of pixels, the smallest unit of an image displayed on a screen.

Types of Computer Graphics

1. Interactive Computer Graphics – Users can interact with the graphics in real-time (e.g., video games, virtual reality).
2. Non-Interactive Computer Graphics – Pre-rendered graphics where user interaction is not required (e.g., animated movies, presentations).

Applications of Computer Graphics

1. Computer-Aided Design (CAD)

• Used in designing buildings, automobiles, aircraft, spacecraft, textiles, etc.
• Supports wireframe modeling and realistic rendering of objects.
