COMPUTER GRAPHICS

INTRODUCTION
Computer graphics is mainly concerned with producing images or sequences of images (animation) using a computer. The hardware and software systems are used to make these images. Producing these Photo-realistic images is an extremely complicated task, but this field has great demand because of the limitless variety of applications. Computer graphics has grown enormously over the past two decades, and many software systems have been developed for generating computer graphics of various sorts. This includes the systems producing 3-dimensional models of the scene, rendering software for drawing these images, and the associated user interface software and hardware[1].

HISTORY

The field of computer graphics was introduced in early 1960’s with Ivan Sutherland. This began with the development of the very simple software for performing the necessary mathematical transformations to produce simple line-drawings of 2- and 3-dimensional scenes.
As days passed, the capacity and speed of computer technology improved, successively more sophisticated computers were achievable[1].
Now, it is possible to produce images that are practically indistinguishable from photographic images[1].

TYPES OF COMPUTER GRAPHICS
There are two types of graphics:

VECTOR GRAPHICS:
It is Used in display devices of ’60s. The components used are:
• Components:
– Display buffer: stores display list
– Display processor: executes commands
– CRT: beam deflected accordingly
• Advantages:
– smooth lines
• Drawbacks:
– Performance
– no filled regions [2]

RASTER GRAPHICS
Raster is a matrix of pixels representing screen space.
• Primitives stored in buffer (memory) as pixels
• Video controller scans out buffer
• Beam’s intensity determi...
