Interactive Graphics $ Non- Interactive Graphics

Interactive Graphics

In interactive computer graphics user have some control over the picture i.e. user can make any change in the produced image. One example of it is the ping pong game. The conceptual model of any interactive graphics system is given in the picture below:- The software has three components. The first is the application program; it creates, stores into, and retrieves from the second component, the application model, which represents the graphic primitive to be shown on the screen. The application program also handles user input. It produces views by sending to the third component, the graphics system, a series of graphics output commands that contain both a detailed geometric description of what is to be viewed and the attributes describing how the objects should appear. After the user input is processed, it sent to the graphics system is for actually producing the picture. Thus the graphics system is a layer in between the application program and the display hardware that effects an output transformation from objects in the application model to a view of the model.

Non- Interactive Graphics

A computer graphics operation that transfers automatically and without operator intervention. Non-interactive computer graphics involves one way communication between the computer and the user. Picture is produced on the monitor and the user does not have any control over the produced picture.
