Introduction computer Graphics:

In this unit, you are introduced to the basics of computer graphics. To begin with we should know why one should study computer graphics. Its areas of application include design of objects, animation, simulation etc.

Though computer graphics gained importance after the introduction of monitors, these are several other input and output devices that are important for the concept of computer graphics. They include high-resolution color monitors, light pens, joysticks, mouse etc. You will be introduced to the working principles of them.

The concept of computer graphics simply means identifying their areas of the screen that are to be illuminated and those that should not be. Most of the regular figures like straight lines, circles etc, are represented by mathematical equations. Given such equations, the first aspect of computer graphics is to convert them to a sequence of points - picture cells or pixels that are to be illuminated (in case of raster graphic display) or simply covert it to a curve that should be traced on the screen. Since many times these jobs have to be very fast and efficient. You will be introduced to a number of such algorithms and also their limitations. 

We also look into the concept of transformations. Whenever as existing is to be moved to a new place or say to be zoomed, the drawing is not done again on the other hand; we only try to transform them. Simple transformation matrices for various operations are also introduced. Further, often we may end up drawing pictures larger than these that can be 

What is computer Graphics?

Computer graphics is an art of drawing pictures, lines, charts, etc

using computers with the help of programming. Computer graphics is made up

of number of pixels. Pixel is the smallest graphical picture or unit represented

on the computer screen. Basically there are two types of computer graphics

namely 

Advantages computer Graphics:

1. It provides tools for producing pictures not only of concrete real world objects but also of abstract, synthetic objects such as mathematical surface in 4D and of data that have no inherent geometry such as survey results.

   2. It have ability to show moving pictures and thus it is possible to produce animations with computer graphics.

  3. With computer graphics user can also control the animation speed, portion of the view, the geometric relationship the object in the scene to one another, the amount of detail shown and on.

  4. The computer graphics provides tool called motion dynamics. with this tool user user can move and tumble objects with respect to a stationary observer, or he can make objects stationary and the viewer moving around them. A typical example is walk through made by builder show flat interior and building surroundings.  In many case it is also possible to move both objects and viewer. 

5. The computer graphics also provides facility called update dynamics. With update dynamics it is possible to change this shape, colour or other properties of the objects being viewed.
