In the perspective of the 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

In reality, the two points A and B are equal to the height of the observer's eye level, if A is located closer to the observer than B, in the perspective of the vertical picture plane, we have:

• a. The point perspective A is higher than the point of perspective B

• b. The point perspective A is lower than the point of perspective B

• c. The point A perspective is as high as the point of perspective B

• d. It depends on whether the perspective is 1 gathering point or 2 gathering points

In reality, two points A and B are equal in height and both are higher than the observer's eye-level, if the distance from A to the picture plane is smaller than the distance from B to the picture plane. (condition is that the vertical picture plane is between the observer and points A, B), in the perspective of the vertical picture plane, we have:

• a. The point perspective A is higher than the point of perspective B

• b. The point perspective A is lower than the point of perspective B

• c. The point A perspective is as high as the point of perspective B

• d. It depends on whether the perspective is 1 gathering point or 2 gathering points

In reality, two points A and B are equal in height and both are lower than the observer's eye level, if the distance from A to the picture plane is smaller than the distance from B to the picture plane. (condition is that the vertical picture plane is between the observer and points A, B), we have:

• a. The point perspective A is higher than the point of perspective B

• b. The point perspective A is lower than the point of perspective B

• c. The point A perspective is as high as the point of perspective B

• d. It depends on whether the perspective is 1 gathering point or 2 gathering points

On the perspective of an inclined picture plane, what is the perspective of two straight lines parallel to the ground plane but not parallel to the picture plane?

• a. Converge at a point on eye-level

• b. Duplicate

• c. There is no common point

• d. Cut at a point above eye level

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

In perspective projection, what is the picture plane used for?

• a. On the picture plane, we draw the perspective projection of the object

• b. On the picture plane, we place the object to draw perspective

• c. The picture plane is used for the observer to stand up

What perspective projection systems are there?

• a. Inclined picture plane and vertical picture plane

• b. Only Inclined picture plane

• c. The only vertical picture plane

What are the characteristics of the 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

In which situation, the perspective of the inclined picture plane is used?

• a. When the observer looks straight, the axis of the cone of vision is parallel to the ground

• b. When the observer looks up, the axis of the cone of vision looks upwards.

• c. When the observer looks down, the axis of the cone of vision looks downwards

• d. Both cases when the observer looks up or down, the axis of the cone of vision looks upwards or downwards.
