<h1>Computer Graphics</h1> | |
<p> | |
Computer graphics are graphics created using computers and the representation of image data | |
by a computer specifically with help from specialized graphic hardware and software. | |
The interaction and understanding of computers and interpretation of data has been made | |
easier because of computer graphics. Computer graphic development has had a significant | |
impact on many types of media and have revolutionized animation, movies and the video | |
game industry. | |
</p> | |
<h1>Overview</h1> | |
<p> | |
The term computer graphics has been used in a broad sense to describe "almost everything on | |
computers that is not text or sound".[1] Typically, the term computer graphics refers to | |
several different things: | |
</p> | |
<ul> | |
<li>the representation and manipulation of image data by a computer</li> | |
<li>the various technologies used to create and manipulate images</li> | |
<li> | |
the sub-field of computer science which studies methods for digitally synthesizing and | |
manipulating visual content, see study of computer graphics | |
</li> | |
</ul> | |
<p> | |
Computer graphics is widespread today. Computer imagery is found on television, in newspapers, | |
for example in weather reports, or for example in all kinds of medical investigation and surgical | |
procedures. A well-constructed <a href="http://en.wikipedia.org/wiki/Chart">graph</a> can present | |
complex statistics in a form that is easier to understand and interpret. In the media "such graphs | |
are used to illustrate papers, reports, thesis", and other presentation material.[2] | |
Many powerful tools have been developed to visualize data. Computer generated imagery can be | |
categorized into several different types: two dimensional (2D), three dimensional (3D), and animated | |
graphics. As technology has improved, 3D computer graphics have become more common, but 2D computer | |
graphics are still widely used. Computer graphics has emerged as a sub-field of computer science | |
which studies methods for digitally synthesizing and manipulating visual content. Over the past | |
decade, other specialized fields have been developed like information visualization, and scientific | |
visualization more concerned with "the visualization of three dimensional phenomena (architectural, | |
meteorological, medical, biological, etc.), where the emphasis is on realistic renderings of volumes, | |
surfaces, illumination sources, and so forth, perhaps with a dynamic (time) component".[3] | |
