Description: A primary goal of a computer graphics system is to provide the user with different views of objects. Sometimes the objects that the user manipulates are simple in nature and can be constructed easily with the primitives provided by the graphics support package. However, in most applications areas the user is concerned with more complex objects. The display of three-dimensional surfaces is one such application area in computer graphics and is the area that this study explores. It is the intent of this study to stimulate the reader's interest in the area of three-dimensional surface generation and display. To provide this stimulation, we combine the power of certain mathematical techniques and a high performance graphics environment to design and implement a set of functions that can be used to create, manipulate, and display three-dimensional solid-filled surfaces. Once developed, the reader will not only be able to use these functions to explore the design, representation, and rendering of such surfaces but also will be able to use these functions in other fields that can benefit from their use such as cartography, robotics, computer vision and artificial intelligence.
