Art Flashcards
Perspective
The art of drawing solid objects on a two-dimensional surface so as to give a realistic impression
A technique for giving an illusion of space to a flat surface
Empirical (useful) perspective
A system of perspective that, unlike linear perspective, relies on direct observation rather than a system of rules
Linear perspective
A system for representing deep space from a single point of view, it is based on the premise that things that are close appear larger than those things that are farther away. Lines will converge systematically to a vanishing point
Atmospheric perspective
A means for achieving the illusion of three dimensional space in a pictorial work of art. Sometimes called areal perspective, it is based on the fact that as object recede into the distance, their clarity of definition and surface contrast diminish appreciably
Horizon line
The line formed by the apparent intersection of the plane established by the eye level with the ground plane. Often described as synonymous with eye level. There is only ever one horizon line
Vanishing point
The point at which lines converge in a drawing
Foreshortening
A technique for producing the illusion of an object’s extension into space by contracting its form
One-point perspective
Linear perspective with just one vanishing point typically in the center of the scene
Multi-point perspective
A scene could have multiple vanishing points depending on the complexity of the subject, and the vantage point from which it is viewed. In third point perspective there are two vanishing points on the horizon and one either below or above the horizon
Ground plane
The horizontal surface below the horizon.
Orthogonal lines
Lines which are directed toward a vanishing point
Orthogonal means right angle; refers to right angles formed by lines such as the corner of a cube shown in perspective
Transversal lines
Refer to upright, vertical objects. If we are viewing frontally, they will run straight up and down and not meet a vanishing point.
Picture plane
The actual flat surface, or opaque pane, on which a drawing is produced. Also refers to the imaginary construct of a transparent plane that always remains parallel to the vertical plane of the artist’s face. The artist draws on paper what he or she sees beyond the plane as though the view were flattened on the plane
Foreground
The closest zone of space in a three-dimensional illusion
Middle ground
The intermediate zone of space in a three dimensional illusion
