Perspective Projections - Transformation
In this projection the center of projection is at limited distance. This projection is termed as perspective projection since in this projection faraway objects seem small and also nearer objects look bigger. Notice Figure 15 and 16. Commonly, the plane of projection is considered as Z=0 plane.
