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. Observer Cone Of Vision Vanishing Points Relationship (Horizontal Distortion) 59 Now let's look at this...

## Top View Of Condition

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...

To sum up The widths of equal-sized objects which diminish in perspective can be found by means of width guide lines that converge to a point on the horizon line.

Similarly-sized elements above or below are drawn with the aid of vertical guide lines constructed at the...

## Pencil

DIMINUTION In this case, both pencils are again lying down, but parallel to the observer's face (i.e., parallel to the picture plane). The foreground pencil would appear, and so is drawn, longer than the rear pencil. This is again explained by the lines of sight and their points of intersection with the picture plane. Study these lines. Suppose many more pencils were laid out in a similar manner. Would this not be identical with, and explain, the familiar phenomenon of the diminishing railroad...

## Mcauaino Line No

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...

## Side View Of Condition

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.

## 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...

## And Straight Ahead

Glance again at pages 40 and 42, where the cube was viewed by looking down and looking up, and note that the vertical lines do not actually remain vertical in the picture but instead appear to converge downwards and upwards respectively. Many books state arbitrarily that such lines should always appear vertical. Although contrary to the truth of seeing, this rule is laid down in order to simplify matters. But such simplification is helpful only in mechanical T-square and triangle perspective...

## 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. And since they are parallel these lines naturally converge to the same point in perspective the diagonals' vanishing point . 74 Drawing Equal-Sized But Unequally-Spaced Elements - Vanishing Point Of Diagonals Method Suppose you had...

## From Realitytheory

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.

## Picture Plane As Seen By Observer

DIMINUTION In this case, the pencils are lying in tandem on a table top, pointing away from the observer. Again the pencil furthest away appears and is drawn shorter. Why this is so is again explained by the way in which the lines of sight leading to each pencil intersect the picture plane. Lines Of Sight Through Picture Plane Applied To Diminution And Convergence 21

## Q

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.

## How To Draw Perspective Of A Round Steers

Then try drawing four equal quad- rants. Note the ends are always x rounded, never pointed. You might find it helpful to sketch a rectangle around the tick marks. This creates four more guide lines within which the shapes can be judged and compared above . Another good technique is to draw the curve carefully in one quadrant. Then transfer tracing paper works well this shape to the other three quadrants, using the axes as reference lines above . The Center Of A Circle Drawn In Perspective Does...

## William A Smith Painting Redbook Magazine

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...

## Perspective Shadow

Now let's again build two cubes using the existing planes as one side of each. This creates two new shade points 1 and 2 which cast shadow points Is and 2s. The two new top shade lines again cast shadows parallel to themselves, thus forming two new sets of parallel, horizontal lines, each of which converges to its own vanishing point on the horizon. 6. Notice that each cube has a total of only two vertical shade lines. The other verticals that had been shade lines in previous steps are now...

If Junior walked around the bench and looked at the end head-on, the true geometry of the end rectangle would appear. The bench top, though, would strongly converge and foreshorten. Notice...

## Foreshortened Cylinder

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. The horizon line serves all sets of lines on horizontal planes while a vertical vanishing line serves all sets of lines on parallel vertical planes. Both are found in the same manner in fact the drawings above and below are identical except for being turned 90...

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...

The pipes are parallel to face and picture plane , so in all views they appear as true verticals. The vanishing points for horizontals must be at eye level which is also in this case the plane of the central visual ray . The top views below show the method of locating these points. The chains and wires converge and foreshorten. Their vanishing points are equidistant from the cone of vision in top view. Therefore they are equidistant from cube in picture. Note equal angles. Again both sets of...

## Major Axis

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...

## Left Vp

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. In the top view, the observer's right hand points to the vanishing point of the first set of lines, while his left hand points to the vanishing point of the second. Now consider the suitcase one horizontal set of lines has become perpendicular to the picture plane. Therefore the central visual...

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...
