Observing from a point of view at a high elevation |
Aerial View |
|
|
The Means by which the illusion of atmospheric distance and depth is created by rendering objects in background space with less edge and value contrast. May also be accompanied by a shift from warmer to cooler hues. softer focus or lighter value |
Aerial/Atmospheric Perspective |
|
|
The reduction or simplification of an image of object to an essential aspect - geometric or organic - of its form or content |
Abstraction |
|
|
The Darkest tone on a form, located on that part of the surface that is turned away from the light source |
Base Tone |
|
|
An italian word light and shade or dark referring to the modeling of volume by depicting light and shade by contrasting them boldly. |
Chiaroscuro |
|
|
A visual area represented by the drawing usually corresponding to a normal person's vision |
Cone of vision |
|
|
a single line that represents the edge of a form or group of forms and suggests three dimensional quality indicating the thickness oas well as height and width of the form it describes; uses subtle over lapping planes
|
contour line drawing |
|
|
In linear perspecting, parallel lines in nature appear to converge as the recede to a point on the horizon line into the picture plane |
Convergence |
|
|
In linear perspective, the phenomenon of more distant objects appearing smaller |
Diminution |
|
|
An arrangement in which positive and negative shapes alternatively command attention. Also known as a positive/negative relationship |
figure/ground relationship |
|
|
Drawn by hand with out any other aid than your own fingers |
Freehand drawing |
|
|
a total mental picture or conception of a form |
Gestalt |
|
|
The actual flat surface of a drawing, synonymous with a drawings opaque picture plane. In a 3D illusion, ground also refers to the area behind an object |
Ground |
|
|
After the Highlight and quarter tone, the next brightest area of illumination on a form - parallel to the rays of light |
half tone |
|
|
In a linear perspective , the line on which all vanishing points are positioned. More accurately described as eye level. |
Horizon Line |
|
|
The placement of images in a 2D format |
Layout |
|
|
After highlight, the next light value of illumination on a form |
Light tone |
|
|
the basic tonality of an objects surface. Regardless of incidental lighting effects or surface texture |
Local Value |
|
|
In Composition: to block forms with the purpose of achieving an overall organization of visual weight |
Massing |
|
|
The Area between the foreground and background of a drawing |
middle ground |
|
|
A method of drawing which delineates form through the use of a variety of values - a range of tones from light to dark |
modeled drawing |
|
|
a method of representing hierarchy of space in a drawing. Overlapping occurs when one subject obscures from view part of a second object |
Overlapping planes |
|
|
a structural description of form in which its complex curves are generalized into major planar zones |
planar analysis |
|
|
the physical vertical and horizontal dimensions of the paper surface |
picture frame |
|
|
the flat, 2D surface on which a drawing is made |
picture plane |
|
|
denotes the illusion of 3D or movement into the picture plane as it relates to the flat, 2D nature of the picture plane itself. We refer to this as plastic space in contrast to perspective space. |
Plastic |
|
|
The relatively weak light that bounces off a nearby surface onto the shadowed side of a form. |
Reflective light |
|
|
A way in which to represent and judge the spatial position of an object in 3D illusionistic space so that forms drawn smaller appear farther away and forms that are drawn larger appear closer |
Relative Scale |
|
|
A relatively flat space, having weight and width but limited depth |
shallow space |
|
|
the visual measurements of objects and spaces between objects |
sighting |
|
|
in linear perspective, the fixed position a person occupies in relation to the subject that is being drawn |
Station point |
|
|
The actual physical structure of texture of the drawing paper containing degrees of smoothness, gloss, or roughness |
surface |
|
|
The flat actual surface area of a drawing which is the product of the length times the width of the drawing paper support |
2D space |
|
|
the changing visual identity of values in juxtaposition, sometimes called value contrast |
Value pattern |
|
|
the potential of any element or area of a drawing to attract the eye |
visual weight |
