In computer science computer graphics is an art of drawing pictures, lines, charts etc on computers screen. To display a picture of any size on a computer screen is very difficult process. It is simplified by using Computer graphics. Graphics on the computer screen are produced by using various techniques and algorithms.
Non-Interactive or Passive Computer Graphics:
In non-interactive or passive computer graphics, the picture is produced on the computer screen, and the user does not have any control over the image. In simple wording the user cannot make any change on an image. Example: screen savers.
In non-interactive computer graphics use can only see the produced image. The produced image can not be changed by the user. It is one-way-communication between user and computer.
Interactive Computer Graphics:
In interactive Computer Graphics user can make some changes on produced image. In simple user have some kind of controlled over picture. Interactive Computer Graphics require two-way communication between the computer and the user. A User can see the produced image and make change by sending his command by using input device.
- Higher Quality resulation
- More precise results
- Greater Productivity
- Lower analysis and design cost
- Significantly enhances our ability to understand data.
Working of Interactive Computer Graphics:
The modern graphics display is very simple in construction. It consists of three components:
- Frame Buffer or Digital Memory Buffer
- A Monitor likes a home T.V.
- Display Controller or Video Controller:
