Question

- vanishing point
- orthogonals
- picture plane

Answer 1

Answer:

vanishing point is a point on the image plane of a perspective drawing where the two-dimensional perspective projections of mutually parallel lines in three-dimensional space appear to converge.

The word orthogonal comes from the Greek orthogōnios meaning "right-angled." While this word is used to describe lines that meet at a right angle, it also describes events that are statistically independent, or do not affect one another in terms of outcome.

the surface of a picture drawn in linear perspective regarded as a transparent plane perpendicular to the lines of sight on which the points of objects in the scene may be considered as projected by straight lines drawn from these points to the eye.

Answer 2

Answer:

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. When the set of parallel lines is perpendicular to a picture plane, the construction is known as one-point perspective, and their vanishing point corresponds to the oculus, or "eye point", from which the image should be viewed for correct perspective geometry.[1] Traditional linear drawings use objects with one to three sets of parallels, defining one to three vanishing points
