[60] Vanishing Points Too Far Apart

Distortion due to excessively close vanishing points is a common error because close vanishing points in general are easier to handle than distant ones. So don't let laziness trap you.

But also avoid the opposite extreme. Placing vanishing points too far apart is also wrong because it results in minimal convergence and hence a sense of flatness.

Extreme Realistic Sketch

Such is the case in the drawing above (right). The flatness is the result either of viewing the subject from too great a distance, or of limiting the drawing to objects very near the center of the cone of vision (see side view). How is it corrected? Since other objects or foreground or background features (clouds, trees, room details, etc.) would normally be visible all around the subject, these, if drawn, would give the picture a realistic three-dimensional effect. (The other solution is to "move closer" to the subject — i.e., use closer vanishing points and stronger convergence.)

Drawing Distortion

IN GENERAL: Convergence is minimal at the center of a picture and increases as you approach the circumference of the cone of vision. Beyond this range unrealistic and unacceptable distortion begins to occur. And naturally the further you go, the worse things get (above).


Perspective Drawing Guide

Height Lines

Assuming this is a 6 x 6 x 6-ft. cube, then the guide lines to vanishing points make all posts shown dotted also 6 ft. high. The top guide lines could be called the 6-ft. "height lines."

If we wished to draw a 6-ft. man at point X we would simply extend forward the appropriate bottom guide line and height line.

Suppose the figure were not on an existing guide line but, for instance, at the spot marked ©.

In that case, first draw the ground line to the left vanishing point. Where this intersects the face of the cube draw a vertical line (shown dotted). (This might be still another 6-ft.-high post in perspective.)

From the top of this imaginary post draw another vanishing line. This is the 6-ft. height line for spot ©.

Suppose you wanted to draw something 12 ft. high. Simply double the 6-ft. height and carry around the new 12-ft. height line (lightly dotted).

If the constructions above were imagined as a series of 6-ft.-high picket fences or walls, then the "height line" would be a real thing instead of an imaginary guide line. Here we see more clearly how these lines establish heights as they are "carried around."

Heights Related To Eye Level — 1: Heights When Observer Is Standing

One Point Perspective Buildings

In this case, those persons (1) of about the same height as the observer and standing on the same ground plane would have their eyes at the same level as the observer's (i.e., on the horizon line).

Those (2) a few inches shorter (e.g., most women) would have the tops of their heads approximately at eye level.

Children - let's say 2% ft. tall, about one-half the height of an adult — would naturally have their head-tops about half way up any standing adult figure. Therefore — no matter where they are placed (3) — the distance from the tops of their heads to eye level must equal their body height.

With eye level about 5 ft. from the floor, a 2-ft.-high wastebasket (4) would stand, wherever it were placed, at the bottom 2/5 of a vertical from ground to eye level.

What about the 5-ft. men on 5-ft.-high stilts? The footrests are at eye level, therefore these 10-unit figures (5) would always appear one-half above eye level and one-half below, regardless of where they stood.

The proportions used above for heights related to eye level are all verified in side view. It should be noted though that these proportions can be worked out "in perspective" without this aid. Reviewing the steps above will show this.

2: Heights When Observer Is In Elevated Position [63]

Assume the observer (1) to be 12 ft. above ground (e.g., a 6-ft.-tall man on a 6-ft. ladder). This means all figures standing on the ground would appear below eye level.

The top of anything 12 ft. high, such as a wall, would therefore be level with eye level (horizon line) and would appear as shown in the drawing below.

Drawing Figures Below The Horizon

6-ft. figures (3) standing along this wall would always be one-half the wall's height—i.e., such figures would always stand at the bottom half of a vertical line dropped from eye level. The dotted line is their "height line."

Therefore 6-ft. figures (4) drawn anywhere on the ground would stand at the bottom half of a vertical dropped from eye level.

4-ft. children (5) would stand at the bottom four-twelfths (one-third) of a vertical from eye level.

Proof of this system — and still another way of determining heights—can be had by first connecting the heads and then the feet of any two figures of similar height. These lines, when brought back, will meet at a vanishing point on the horizon line (see dotted lines).

[64] 3: Heights When Observer

Is Sitting

Here the observer's eye level is about 4 ft. above the ground. In such a case, all others who are sitting (1) would also have their eyes at eye level.

Standing figures (2) would always have their heads above eye level. If they were 6 ft. tall then their lower four-sixths (two-thirds) would always be below eye level, and their upper two-sixths (one-third) always abova (I.e., their rib cages would always be at eye level)

A boy (3) exactly 4 ft. high would always have his head at eye level.

Again, if the heads and feet of any two figures of equal height were connected (see dotted lines) these lines would always converge to one point on the horizon line.

Point Perspective Drawing

4: Heights When Observer Is Lying Down

Here the observer's eye level is about 1 ft. above the ground. Therefore objects smaller than 1 ft. would appear below eye level (e.g., most beach balls).

All taller objects would have their 1-ft. level at eye level — e.g., the 6-ft.-tall figures (2) would always appear one-sixth below and five-sixths above eye level.

The 5-ft.-high girl (3) would appear one-fifth below and four-fifths above eye level regardless of location.

The 2-ft.-high dog (4) would always appear one-half above and one-half below eye level.

And the top of the l-ft.-high sand castle (5) would appear at eye level.


Heights Outdoors... And Indoors [65]

Buildings Perspective Drawing

From the roof of a 30-story building all taller buildings will appear above the horizon line while those lower than 30 stories will appear below. (This assumes all buildings have similar floor heights.)

Therefore, the eye level-horizon line will cut across the 30-story level of all buildings that have one.

Naturally the 60-story Pan Am Building in the foreground appears taller than the 102-story Empire State Building because it is closer to the observer. But in both cases their 30-story levels are on the same horizontal plane as the observer's eye level.

Watercolor Interior Perspective

In sketching a room interior, many heights can be found by relating them to wall heights.

If a room is 8 ft. high then somewhere along the rear wall (1) or along one of the side walls (2) tick off 8 equal divisions. A 7-ft.-high door next to (1) or (2) is easily drawn.

Similarly, a door knob 3 ft. above the floor is located by the 3-ft. height line (3).

Suppose we wanted to draw a 6-ft. figure in the foreground. The dotted line (4) would provide the height.

Find the vanishing point of the receding horizontals and note that the eye level of the drawing is at the 4-ft. level. Therefore all 6-ft. figures would appear four-sixths below and two-sixths above eye level, no matter where they stood.

Drawing a 3-ft.-high chair at (5) requires carrying the door knob height across to this point. A 3-ft-high boy (6) could be drawn by "carrying" this height line "around" the vertical at (7). (The guide lines shown use the center vanishing point, but any vanishing point along eye level could be used.) Notice how the boy's height can always be verified by the 3-ft. height line from the left.

The l-ft.-round lamp hanging over the chair from a 1 ft chain is drawn by using the guide lines shown as arrows.

The ground is level, so the eye level-horizon line "cuts" across the same level — chest height — of all the figures

The ground slopes toward the water. The adults standing on the higher ground have their head-tops approximately at eye level (horizon line). The adults standing along the shoreline have their head-tops generally midway between the ground and the horizon line. Note that this changing relationship of head height to horizon line almost exclusively

"explains" that the land is sloping.

In both pictures we know that the cross-ties are really equal-sized elements. Yet diminution makes them appear successively smaller. The rails converging to a vanishing point act as guide lines for the widths of these cross-ties.

The diminution of other "flat" objects, such as boats, cars, people lying on a beach, etc., can be determined by the convergence of similar "width" guide lines.


Sketch the first object (1) in a file.

Converging guide lines to eye level will define "widths" of equally long objects in the same file (2).

Objects outside of original guide lines (3) can be drawn by transferring guide line widths to left or right (e.g., dim. x = dim. x or dim. y = dim. y).

Suppose (say by means of an hydraulic jack) one of the objects (4) were at a higher or lower level. Its width is easily found by erecting verticals from the appropriate points on the guide lines to the new level. (Naturally the same eye level and vanishing point as before would be used when drawing the object.)
