Today, a high quality graphics displays of personal computer provide one of the most natural means of communicating with a computer

It provides tools for producing pictures not only of concrete, ‘real-world’ objects but also of abstract, synthetic objects, such as mathematical surfaces in 4D and of data that have no inherent geometry, such as survey results.
It has an ability to show moving pictures, and thus it is possible to produce animations with interactive graphics.
With interactive graphics use can also control the animation by adjusting the speed, the portion of the total scene in view, the geometric relationship of the objects in the scene to one another, the amount of detail shown and so on.
The interactive graphics provides tool called motion dynamics. with this tool 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 thorough made by builder to show flat interior and building surroundings. In many case it is also possible to move both objects and view
