Context

The use of high performance workstations has resulted in much of the graphics work, previously carried out on specialised computer systems, being done on desktop workstations. As these workstations become more powerful, the need is increasing for more complex graphical systems, additionally the standard graphical applications are now migrating to the mass markets, the need for cognisant students is increasing. This module provides the student with an understanding of the techniques used in producing the computer graphics used in many different areas of commerce and industry. Particular emphasis is placed on understanding 3D graphics and the fundamental requirements for extending the 2D model to 3D.
