The Use of Projective Geometry in Computer Graphics

The ultimate goal of all 3D graphics systems is to render 3D objects on a two—dimensional surface such as plotter output or a workstation screen. The approach adopted by most graphics systems is to perform a central or parallel projection of the objects onto the view surface. These systems have to make use of the mathematical results of projective geometry. This monograph has as its aim the derivation of a framework for analyzing the behavior of projective transformations in graphics system...
