[citation needed] Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by ...
A vanishing point is a point on the image plane of a perspective rendering where the two-dimensional perspective projections 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 ...
Reductio ad absurdum, painting by John Pettie exhibited at the Royal Academy in 1884. In logic, reductio ad absurdum (Latin for "reduction to absurdity"), also known as argumentum ad absurdum (Latin for "argument to absurdity") or apagogical arguments, is the form of argument that attempts to establish a claim by showing that the opposite scenario would lead to absurdity or contradiction.
In painting, photography, graphical perspective and descriptive geometry, a picture plane is an image plane located between the "eye point" (or oculus) and the object being viewed and is usually coextensive to the material surface of the work. It is ordinarily a vertical plane perpendicular to the sightline to the object of interest.
Silverpoint is one of several types of metalpoint used by scribes, craftsmen and artists since ancient times. Metalpoint styli were used for writing on soft surfaces (wax or bark), ruling and underdrawing on parchment, and drawing on prepared paper and panel supports. For drawing purposes, the essential metals used were lead, tin and silver.

In some parts of the United States and Canada, some confusion may result as the ...
