exam #2

Question 1

ellipse

Answer 1

symmetrical foreshortened view of a circle

Question 2

major axis

Answer 2

x axis of ellipse

Question 3

minor axis

Answer 3

y axis of ellipse

Question 4

horizontal ellipses’ proportions are determined by

Answer 4

viewer’s eye level/perspective

Question 5

ellipses become more visible as

Answer 5

it moves further from the eye level

Question 6

matrix

Answer 6

a formative pattern

Question 7

spatial conventions

Answer 7

overlapping, relative position, diagonals, chiaroscuro, atmospheric perspective

Question 8

picture plane

Answer 8

a window through which viewers can experience a convincing illusion of deep space

Question 9

overlapping

Answer 9

shapes that partially obscure other shapes are seen as being closer in space

Question 10

relative position

Answer 10

shapes on a ground plane that are positioned lower in the picture are seen as closer than those higher up

Question 11

diagonals

Answer 11

forms positioned diagonally across the picture appear to recede in depth while vertical/horizontal forms do not

Question 12

chiaroscuro

Answer 12

gradual blending of light and shade to create a 3D illusion

Question 13

atmospheric perspective

Answer 13

closer volumes are generally described with stronger value contrasts/sharper detail while more distant forms have progressively less contrast/softer detail

Question 14

filippo brunelleschi

Answer 14

a Florentine architect and innovator of a mathematical system that allows artists to draw a heightened 3D illusion of form/space called linear perspective

Question 15

linear perspective incorporates

Answer 15

diminution, foreshortening, convergence

Question 16

diminution

Answer 16

objects of equal size appear smaller as their distance from viewer increases

Question 17

foreshortening

Answer 17

edges and planes appear longest when they’re parallel to the picture plane.

Question 18

convergence

Answer 18

edges and planes that are parallel to each other in physical reality appear to come together toward a common point as they recede in depth

Question 19

station point (SP)

Answer 19

the fixed position of the one eye of the observer, the position form which the subject is seen

Question 20

eye level (EL)

Answer 20

a horizontal plane through the station point, aka horizon line

Question 21

picture plane (PP)

Answer 21

an imaginary transparent plane that sits between the observer and subject, which is always perpendicular to the central visual ray

Question 22

central visual ray (CVR)

Answer 22

the fixed direction of viewing, expressed as a single imaginary line from the station point which is always perpendicular to the picture plane

Question 23

visual ray (VR)

Answer 23

the theoretical path of a light ray; an imaginary straight line

Question 24

vanishing point (VP)

Answer 24

the point where receding parallel lines appear to converge

Question 25

angle of vision (< of V)

Answer 25

the limitation of how much the field of vision is included in the drawing(both height and width)

Question 26

one point perspective (parallel perspective)

Answer 26

when drawing rectangular solids that have facing planes parallel to the picture plane

Question 27

which vanishing point diagram would be best to draw a room interior seen from birds eye view?

Answer 27

the highest line

Question 28

which vanishing point diagram would be best to draw a room interior from the center of the room?

Answer 28

the center line

Question 29

which vanishing point diagram would be best for drawing a room interior from a bug’s eye view?

Answer 29

the lowest line

Question 30

which vanishing point diagram would be best suited to draw a room interior seen from a place that’s closer to a wall on the right?

Answer 30

a line 3/4s down with vanishing point to the right

Question 31

perspective grid

Answer 31

a matrix made up of lines on paper that converge to vanishing points

Question 32

perspective midpoint

Answer 32

can be found with diagonals in a foreshortened square/rectangle

Question 33

two point perspective (angular perspective)

Answer 33

used when drawing rectangular solids/interior spaces viewed diagonally (or turned at an angle not parallel to the picture plane)

Question 34

three point perspective (oblique perspective)

Answer 34

used when vertical edges recede from the picture plane toward a third vanishing point located above eye level (zenith) or below eye level (nadir)

Question 35

zenith

Answer 35

a vanishing point above eye level used in 3pt perspective

Question 36

nadir

Answer 36

a vanishing point located below eye level used in 3pt perspective
