ISRO | ISRO CS 2013 | Question 79
In graphics, the number of vanishing points depends on
(A) the number of axes cut by the projection plane
(B) the centre of projection
(C) the number of axes which are parallel to the projection plane
(D) the perspective projections of any set of parallel lines that are not parallel to the projection plane
Explanation: A vanishing point is a point on the image plane of a perspective drawing where the two-dimensional perspective projections (or drawings) of mutually parallel lines in three-dimensional space appear to converge.
So, (D) is the correct option.
