Overview of Computer Graphics

The term Computer graphics has multiple meaning:

• Field of science, which studies the manipulation of visual and geometric information using computational techniques. Computer graphics as an academic discipline focuses on themathematical and computational foundations of image generation and processing rather than purely aesthetic issues.
• The economic branch which deals with the creating and modification of an image on a screen.
• The images created or manipulated in two or three dimensions (2D or 3D respectively), see 2D computer graphics and 3D computer graphics.

Computer graphics is often differentiated from the field of visualization, although the two fields have many similarities.

Applications of Computer graphics are:

• Digital art
• Special effects
• Visual effects
• Video games

Connected studies of Computer graphics are:

• Computer vision
• Image processing
