QN=1

Which visual law relates to perspective projection ?

• a.

  The farther the distance from the object to the observer is, the smaller the object is

• b.

  The further away the object becomes, the more faint and unclear it will be

• c.

  The human eye has the ability to self-regulate to focus on seeing an object more clearly

• d.

  All above

QN=2

Where is the apex of Cone of Vision?

• a.

  On the Picture Plane

• b.

  On the Groud Plane

• c.

  At the observer’s eyes

QN=3

In the perspective of vertical picture plane, the perspective of a circle placed parallel to the ground plane and at the eye level is shown as:

• a.

  A circle

• b.

  An ellipse

• c.

  A horizontal line

• d.

  All three cases are wrong

QN=4

What are the characteristics of vertical picture plane?

• a.

  The picture plane is inclined at an angle greater than or less than 90 degrees to the ground plane

• b.

  The picture plane is parallel to the ground plane

• c.

  The picture plane coincides with the ground plane

• d.

  The picture plane is perpendicular to the ground plane

QN=5

What is the characteristic of perspective projection of two lines that are parallel but not parallel to the picture plane ?

• a.

  There is a common vanishing point

• b.

  There are two vanishing points

• c.

  There are countless vanishing points

• d.

  There is no convergence

QN=6

What is the characteristic of the inclined picture plane?

• a.

  The picture plane is parallel to the ground plane

• b.

  The picture plane coincides with the ground plane

• c.

  The picture plane is perpendicular to the ground plane

• d.

  The picture plane is not perpendicular to the ground plane

QN=7

In the perspective of vertical picture plane, the distance from the horizon line to the bottom of the picture plane is determined:

• a.

  By the distance from the point of view to the picture plane

• b.

  By the distance from the point of view to the object

• c.

  By the distance from the point of view to the ground plane

QN=8

On the perspective of an inclined picture plane, where is the vanishing point of two straight lines that parallel to both the picture plane and the ground plane?

• a.

  Converge at a point on eye level

• b.

  Duplicate

• c.

  There is no vanishing point

• d.

  Cut at a point above eye level

QN=9

What is diminution ? Choose the correct statement.

• a.

  Diminution - objects of equal size appear smaller as their distance from the observer increases

• b.

  Diminution - objects of equal size appear bigger as their distance from the observer increases

• c.

  Diminution - objects of equal size appear as equal as their distance from the observer increases

QN=10

It is based on the fact that lines of sight intercepted by an opaque object simply stop, so that objects beyond are partially or totally concealed (literally “blocked off”). The result is a strong sense of foreground and background planes, forwardness and beyondness, in other words, DEPTH. What does “it” mention?

• a.

  Diminution

• b.

  Overlapping

• c.

  Convergence

• d.

  Foreshortening
