In case that the objects to be displayed is distorted as shown in the picture, if you want to adjust to limit this distortion, the observer must: ( see picture 48)

• Higher the eye level line

• Lower the line of eve level

• Adjusted the view point to set the object within the cone of vision

• Go ahead, stand closer to the surface of the painting

In the following figures, which one the perspective of the cone is drawn

correctly? (See picture 49)

• Figure a

• Figure b

• Figure c

• None of them is correct

Look at this picture and find out its mistake (see picture 50)

• Wrong position of the vanishing points

• Wrong position of the horizon line

• Wrong point of the vanishing points and height of rectangular block

• Wrong determination of the height of rectangular block

What kind of perspective is in this following picture ? (See picture 47)

• Perspective of inclined picture plane

• Two-point perspective

• One-point perspective

• Any point perspective

In perspective of vertical picture plane, a square placed parallel to the ground plane is represented by:

• A square

• An isosceles trapezoid

• A straight line

• Cases of isosceles trapezoid, segment, quadrilateral can all occur

When drawing perspective projection, if the object is outside the field of vision, what happens?

• The perspective projection of the obiect is enlarged

• The perspective projection of the object gets smaller

• The perspective projection of the object is transformed

• The perspective projection of the object remains unchanged

Look at this picture and find out its mistake (see picture 51)

• Wrong position of the vanishing points

• Wrong position of the horizon line

• Wrong position of the vanishing points and the horizon line
