Describe interactive model of computer graphics and application areas of interactive computer graphics.                                                                                                                                                      

Interactive 3D Computer Graphics  

 Computer graphics includes the process and outcomes associated with using computer technology to convert created of collected data into visual representations. The computer graphics field is motivated by the general need for interactive graphical user interfaces that support mouse windows and widget functions. Other sources of inspiration include digital media technologies, scientific visualization, virtual reality, arts and entertainment. Computer graphics encompasses scientific, art, and engineering function. Mathematical relationships of Geometry define many of the components in a particular computer graphics scene or composition. Physics fundamentals are the basis for lighting a scene. The layout, color, texture and harmony of a particular composition are established with Art and Perception principles. Computer graphics hardware and software are rooted in the engineering fields. The successful integration of these concepts allows for the effective implementation of interactive and thee- dimensional computer graphics. Interactive 3D graphics provides the capability to produce moving pictures of animation. This is especially helpful whine exploring time varying phenomena such as weather changes in the atmosphere, the deflection of an airplane wing in flight, of telecommunications usage patterns. Interaction provides individual users the ability to control parameters like the speed of animations and the geometric relationship between the objects in a scene to one another.

The Building Blocks of Interactive 3D Computer Graphics   

Primitives:  primitives are the basic geometrical shapes used to construct computer graphics scenes and the resulting final images. Each primitive has attributes like size, color, line and width. For two dimensions, examples of primitives include: a line, circle, ellipse, arc, text, plotline, polygon, and spine. For 3D space, examples of primitives include a cylinder, sphere, cube and cone. 3D viewing is complicated by the fact that computer display devices are only 2D. 

Conceptual frame work for interactive graphics  At the hardware level a computer receives input from interactive devices and output images to a display device. The software has three components.

Application program: It is used to create, stores and retrieves from second component.  

Application model  Computer graphics may be used in the following areas: Computational biology, Computational physic , Computer-aided design, Computer simulation, Digital art, Education, Graphic design, Info graphics, Information visualization, Rational drug design, Scientific visualization, Video Games, Virtual reality, Web design.
