ABSTRACT
The term computer graphics refers to the generation, representation, manipulation, processing and visual display of data using a computer. Graphics are useful for visualizing physical phenomena and data as well as the volume visualization of complex datasets. Many commercial scientific and engineering software packages have graphics functionality. Software packages would not be possible without the continued development and improvement of graphics algorithms. In traditional graphics systems, image data are modeled and stored as Cartesian coordinates or as vectors. A long-term goal of computer graphics has been the production of photorealistic images, resulting in much research devoted to the area of shading and illumination. Graphics algorithms respond to Graphics input based on logical device categories or by using callback functions. The fields of human-computer interaction and perception play a role in creating packages and images that respond and behave in a reasonable fashion.
