Displaying Three-dimensional Objects on the Screen

Abstract

In the previous chapter we discussed various ways of manipulating three-dimensional objects. We now know how to translate, scale and rotate them, and are, thus, familiar with the transformations necessary to perform quite complex changes on the original object. In spite of our ability to make these alterations, as yet, we cannot display the transformed objects on the screen! In order to do so, we must consider first a few related topics.
