The last decade has seen a revolution in software engineering tools and techniques. This revolution has been fueled by the ever-increasing complexity of the software component of delivered systems. Although the software component of delivered systems may not be the most expensive component, it is usually, however, “in series” with the hardware component; if the software doesn’t work, the hardware is useless

The term computer graphics refers to the generation,representation, manipulation, processing, and display of data by a computer. Computer-generated images may be real or imagined, animated or still, two-dimensional (2-D) or three-dimensional (3-D).Today most computers, particularly those in the PC,Macintosh, or workstation categories
