CHAPTER 11 — Projections

As discussed in chapter one, 3D computer graphics consists of two activities: (1) Creating an imaginary world inside a computer, and (2) producing two dimensional images of that world from various viewpoints.

Producing a 2D image from a 3D image is an example of projection. This chapter discusses the fundamental notions of projection. The advanced topics are left for your graphics text book.

Chapter Topics:

• Projections in general.
• Projecting on vector onto another.
• Example vector projections in 2D.
• Example vector projections in 3D.
