Line
|
Path traced by a moving point
|
Outline
|
Defines a two-dimensional shape
|
Countour line
|
Lines we draw to record the boundaries we perceive of 3-D forms
|
Directional line
|
Direct our eyes around an image and/or suggest movement
|
Implied line
|
Lines we pick up on that aren't actually there, close proximity of objects can lead to us connecting them
|
Shape
|
A 2-D form that occupies an area with identifiable boundaries created by line, shift in texture, or shift in color
|
Mass
|
A 3-D form that occupies a volume of space
|
Figure/ground
|
F: shape we detach from surroundings and focus on
G: the surrounding visual info the figure stands out from (the background)
|
Positive/negative shape
|
P: shapes we perceive as figures
N: shapes we perceive as ground
|
Modeling
|
Stimulating the effects of light and shadow in order to portray optically convincing masses(3-D form)
|
Value
|
Shades of light and dark/ relative lightness or darkness
|
Chiaroscuro
|
Artists employ values(lights and darks) to record contrasts of light and shadow in the natural world, contrasts that model mass for our eyes
|
Hatching
|
Areas of closely spaced parallel lines
|
Cross-hatching
|
Additional sets of parallel lines laid across the first hatching
|
Color wheel
|
Circular arrangement of hues used to illustrate a particular color theory or system
