Learning Event 1:
1. Three-point perspective occurs when none of the object's surfaces
(height, width, and depth) are parallel to the picture plane (fig 3-1).
Three-point is usually needed when the station point is close to a large
object, such as when you are looking up at a nearby ship or tall building.
The horizon in this case is usually very low, or entirely below the object.
If you were looking down from above, the horizon may not appear in the view
a. When constructing this type of perspective, use your artistic
ability to place the vanishing points, particularly the VP for the vertical
A good rule to follow says that small objects will usually look
better if the three vanishing points are well separated.
emphasize the bigness of an object, sharp diagonal lines are important.
Here the closeness of the vanishing points strengthens the bigness effect.
b. Horizontal diagonal lines must end at the eye level line. One line
cannot be higher or lower than the other.
Regardless of their distance
apart, they must be established on the same eye level.
