THE SIZE OF THE OBJECT DOES NOT MATTER. FOR INSTANCE, A PRISM OF THIS PROPORTION (below) DRAWN AT THIS ANGLE COULD BECOME A BOOK, AN OFFICE BUILDING, OR EVEN A BILLBOARD. OR, THE EXACT SAME SHAPE COULD BE LAID DOWN TO BECOME A PACKAGE FOR HORIZONTAL OBJECTS OF SIMILAR PROPORTIONS, e.g., A BED, A CIGAR BOX, A GUN, A BOOK, A SWIMMING POOL, ETC. (Note Lines 2 which previously converged to the left now converge downwards. Lines 1 which previously converged downwards now converge to right.)

In a perspective drawing this distortion is eliminated simply by placing the vanishing points further apart. The diagram at right shows that the observer points to increasingly distant vanishing points as he steps back. THEREFORE PLACING VANISHING POINTS FURTHER APART ELIMINATES DISTORTION AT EDGES OF DRAWING. IT MEANS OBSERVER HAS STEPPED BACK AND SEES MORE WITH HIS FIXED CONE OF VISION.

CONVERGENCE PARALLEL LINES APPEAR TO APPROACH EACH OTHER AS THEY RECEDE. In this example, the pencils are lying parallel to one another, pointing away from the observer. They would appear to converge and are so drawn. Why this is so is again explained by the lines of sight. Those leading to the far ends of the pencils (the pointed ends) intersect the picture plane relatively close together. Those to the near ends (the eraser ends) intersect the plane further apart. Another way of visualizing...

Chapter 12 INCLINED PLANES-INTRODUCTION Since the bottom of this box is horizontal, its converging lines always vanish to eye level. An observer pointing in the direction of the box horizontally therefore points to its vanishing line first drawing . So it is with the pivoting box top. An observer pointing in the same direction as this variously-inclined plane points to its successive vanishing lines. Box and box top are parallel, therefore only one vanishing line eye level . Here, the box top...

Suppose we wanted to divide face A of this object into two equal spaces, face B into four equal spaces, and the top into eight equal spaces. BELOW is the solution when each face is viewed head-on. AT RIGHT is the same solution in perspective. STEP 2 Connect point 7 to opposite lower corner and continue to horizon line. This gives us a special vanishing point for all guide lines parallel to this one. STEP 1 From lowest corner of face to be divided draw horizontal line and tick off the number of...

So It Is Accurate As Well As Useful To Think Of The Eye Level As The Vanishing Line For All Horizontal Lines And Planes

What Locates The Vanishing Point Of A Particular Set Of Parallel Lines 29 This is what our observer sees. His eye level is the vanishing line for horizontal lines. Actually, it is a plane seen edge-on. But what located the specific vanishing point Across page we saw that the horizontal sight line aimed at infinity parallel to the tracks points to it. So, very simply the vanishing point of the tracks is the point at which the sight line parallel to them intersects the picture plane. The...

FORESHORTENING LINES AND SURFACES ALWAYS APPEAR LONGEST WHEN PARALLEL TO THE OBSERVER'S FACE i.e., TO THE PICTURE PLANE . AS THEY REVOLVE AWAY FROM THIS POSITION THEY APPEAR INCREASINGLY SHORTER. Why this is so can be understood by noting how the lines of sight intersect the picture plane for each position of the pencil. Note when the pencil appears as a small circle, i.e., when just the eraser or the pointed end is in view, then it is 100 foreshortened and aligned with the central visual ray.

Table Drawn Perspective

The following concept is the basis for most of the aids employed in finding perspective depths The diagonals of any square or rectangle see above will always intersect at the exact center of the figure in other words, at a point equidistant from top and bottom and from left and right edges. Thus, on this ping pong table seen directly from above, the two diagonals will naturally intersect at the net which is equidistant from the ends. Now, when the table is drawn in perspective, where should the...

In Other Words The Observer Simply Points In The Same Direction As The Lines In Order To Find Their Vanishing Point

30 Why The Parallel Pointing Method Of Locating Vanishing Points Is Important In T-square and triangle perspective, this method of locating vanishing points is an essential step. Thus, to draw the object below, we first construct a top view or plan left , showing the object, the picture plane seen as a line and the observer's position. On this plan, sight lines pointing parallel to the object lines are drawn to locate the vanishing points on the picture plane. Other sight lines project the...

We've seen that this important line is straight and horizontal, but what determines its location Very simply IT IS AWAYS ON THE SAME LEVEL AS THE OBSERVER'S EYES. In other words, the observer's eye level - an imaginary plane at the level of the eyes and parallel to the ground dictates the location i.e., the height from the ground of the vanishing line for all horizontals in a given drawing. A side view of the drawing above will show the eye level and the ground plane from their edges and...

But such simplification is helpful only in mechanical T-square and triangle perspective...

One Set Of Horizontals Will Be Indicated By Chains

NOW A QUICK REVIEW We see things, as shown on pages 18 and 19, by means of a central visual ray surrounded by a cone of vision. The central visual ray focuses upon the center of interest, while the cone of vision defines the roughly circular area within which we can see things clearly. Perpendicular to the central visual ray is the picture plane, which may be thought of as a piece of glass or the drawing paper or canvas itself. The observer's face will also be considered perpendicular to the...

Height

An examination of the top view of the first example left and the side view of the second above will show why this works. Note that once the width or height lines are drawn, any set of parallel lines will strike off equally-long rectangles by becoming their diagonals.

By applying the notion of lines of sight through a picture plane to simple views of pencils of equal length, we can more precisely define the visual basis of DIMINUTION, CONVERGENCE, FORESHORTENING, AND OVERLAPPING, and explain diagrammatically why the appearance of an object so frequently differs from its reality.

DIMINUTION - OBJECTS OF EQUAL SIZE APPEAR SMALLER AS THEIR DISTANCE FROM THE OBSERVER INCREASES. These pencils are both standing perfectly upright but not directly in line with one another if they were, the rear pencil would be overlapped and concealed . Pencil B appears smaller than pencil A. This is so because of the manner in which the lines of sight leading from eye to objects intersect or project onto the picture plane.

Thus, the diagrams on pages 28 and 29, showing a flat ground plane parallel to observer's eye level, are realistic and the conclusions drawn from them are valid. In fact, artists have for ages, and in every field of fine and applied art, used the concepts eye level and nature's horizon line interchangeably. In practical terms, this means that as the observer's eye level is raised or lowered, nature's horizon line always accompanies it and appears at the same horizontal level. It also means that...

So it is important to realize that vertical vanishing lines and the horizon line eye level serve the same purpose and are similar in concept. Both contain the vanishing points for parallel sets of lines which lie on parallel planes.

Here, the central visual ray points at something in the sky or at the top of a telegraph pole. The cone of vision barely sees the eye level plane with its lowest sight lines. In the picture therefore, the eye level horizon line is close to the bottom. LOOKING DOWN. Here, the central visual ray points not at the distant horizon but down at the tracks. The cone of vision, therefore, just barely includes the eye level plane. Note the proximity of top sight lines and eye level. In the...

This is true regardless of the angle or position of the ellipse. So don't make the mistake of drawing a foreshortened square and using its center to locate the major axis of an ellipse. The resulting figure would look something like this right . Also, if you wish to draw half a circle or cylinder you cannot draw an ellipse and consider either side of the major axis to be half of a fore- shortened circle. E.g., the figure at left is not half but less. The two at right, however, are each proper...

When the observer shifts his attention to the structure, the railroad ties and black lines become oblique to the picture plane, as do the rails and the fancy lines of the structure, in another direction.

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. 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...
