Introduction

The creation process to generate an image of object on a computer display screen requires geometric modeling of that object. Geometric objects have many important characteristics, such as size, shape, location, orientation, and certain spatial relationships to each other.

To describe, measure, and analyze these characteristics consistently and quantitatively requires a frame of reference called a coordinate system. There are many kinds of coordinate systems, each offering special advantages depending on the problem to be solved.

In what follows, we are going to discuss these different coordinate systems and show how the combination of these coordinate systems used to construct a computer graphics display. Moreover, we are going to summarize various mathematical topics that are relevant to computer graphics.
