How can an infinite view volume be changed into a finite view volume? a) By changing the length of window boundaries b) By changing the angle of projection c) By changing the size of the window d) By specifying positions for one or two additional boundary planes
Answer: d Explanation: An infinite view volume can be changed into a finite view volume by specifying positions for one or two additional boundary planes. These z,-boundary planes are referred to as the front-plane and back-plane of the viewing volume. The front and back planes are parallel to the view plane at specified-positions zfront and zback.
