Space

  1. 1. SPACE
  2. 2. Space, has been like other elements dealt with in all the earlier assignments but will be dealt with in detail here. The nature of space is rather complex because there are many ways space can be viewed. Space may be positive or negative, flat or illusory, ambiguous, or conflicting.
  3. 3. SPATIAL REPRESENTATIONS ON 2D SURFACES In creating the illusion of three-dimensional space one tends to assume that spatial illusion is concerned with the study and application of perspective. Linear perspective (Fig A and B) is just one of many methods used by the visual artist to deal with spatial representation. Throughout art history the visual artist has represented space in a variety of ways. Space is, actually intangible as compared to texture, pigment, shape etc. However, sensitive use of space is often the most important factor in a composition. The three-dimensional visual artist is primarily concerned with a pleasing displacement of space by form, and the two-dimensional visual artist is primarily concerned with its arrangement on the picture plane or its illusion in the form of depth.

  5. 5. SPATIAL ANALYSIS two-dimensional representation of space Decorative Space Infinite Space Limited Space Intuitive Space Decorative Space – is to work on the surface of the picture plane. Greatly used in graphic and typographic design. A perfectly flat twodimensional surface is extremely difficult to achieve because of figure-ground relationships. The slightest manipulation of line, shape, colour, texture, or value generates a depth illusion.
  6. 6. Infinite Space Infinite spatial concepts have dominated Western visual art from the beginning of the Renaissance to the time of the Industrial Revolution, the beginning of the modern period. A visual art solution that emphasizes infinite space uses the picture plane as a starting point. It is to looking through an open window at a landscape that seems to go to infinity.
  7. 7. Limited Space Contemporary visual artists tend to incorporate many of the elements of both decorative and infinite spatial concepts in their work, resulting in limited space.
  8. 8. Intuitive Space Spatial methods are often used arbitrarily, and in combination when necessary, to achieve the results desired. A rule of thumb is: if the combination works, use it, such is the case with the intuitive spatial organizational concept. Used throughout much of modern visual art history, the visual artist has taken liberties with established rules in order to communicate an intent. The use of intuitive space is often difficult to classify because it uses one or more of the above concepts in combination with various perceptual devices.
  9. 9. Positive and Negative Space Positive space is what surrounds a negative form and negative space is what surrounds a positive form. All positive forms contain positive space, but positive space is not always perceived as a positive form. Similarly, all negative forms contain negative space, but negative space is not always perceived as a negative form. This is because positive space can be a background for negative forms and negative space for positive forms, and backgrounds are not normally recognized as forms which usually exist within a certain degree of isolation. Positive (or negative) space completely or nearly isolated by negative (or positive) forms can be identified as positive (negative) form, but such forms are generally hidden unless we consciously look for them. If they are found frequently and regularly, then the figure-ground relationship is reversible: at one moment we find positive forms and negative space, at another moment we find negative forms and positive space. (Fig. 1a) Fig 1 a
  10. 10. Flat and Illusory Space Space is flat when all the forms seem to lie on the picture plane and be parallel to it. The forms themselves should be flat too, and appear equidistant from the eye, none nearer and none farther. It is possible, however, that we can feel the space surrounding the forms to be very deep, leaving all the forms floating on the picture plane.
  11. 11. In a flat space situation, forms can meet one another by touching, interpenetration, union, subtraction, intersection, coinciding, or just be in detachment, but they can never meet by overlapping. (Fig. 1b) Overlapping suggests that one form is nearer to our eyes than another, Fig 1 b thus rendering the space illusory to some extent. (Fig. 1c) Variations in shape, size, colour, and texture may also destroy the flatness of space, but this does not always happen. Space is illusory when all the forms seem not to lie on or Fig 1 c be parallel to the picture plane. Some forms may appear to advance, some to recede, some to present their frontal views, and some to show their oblique views. The forms themselves may be flat or three-dimensional. The composition area opens up like a window or a stage where the forms are displayed in varying depths and/or at different angles. (Fig. 1d) Fig 1 d
  12. 12. Flat Forms in Illusory Space Forms are considered flat when they have no apparent thickness. Flat forms in illusory space are like forms made of thin sheets of paper, metal, or other materials. Their frontal views are the c fullest, occupying the largest area. Their oblique views are narrowed, and occupy less area. The following are some common ways flat forms can be used in illusory space: a) Overlapping - When one form overlaps another, it is seen as being in Fig 2a - 1 front of or above the other. The flat forms may have no appreciable thickness, but if overlapping occurs, one of the two forms must have some diversion from the picture plane, however slight the diversion may be. (Fig. 2a - 1) Creating depth illusion is to place one image so that it partially obstructs the view of another image. The image that intercepts the visible surface of another image is perceived as being closer to the viewer. The device of overlapping is very strong and will take precedence over other spatial clues. A small image positioned in front of a large image will appear Fig 2a - 2
  13. 13. Transparency Transparency is another form of overlapping that, in addition to creating a depth illusion, often creates a spatial contradiction. It can express two or more spatial positions simultaneously, and it tends to create ambiguity, or what might be referred to as equivocal space. Transparency can also be used to show simultaneously the exterior and interior views of an object.
  14. 14. b) Change in size - Increase in size of a form suggests that it is getting nearer, whereas decrease in its size suggests that it is farther away. The greater the range of change in size present in the composition, the deeper is the illusion of spatial depth. Fig 2b (Fig. 2b) c) Change in colour - On a white background, darker colours stand out much more than lighter colours , thus appearing closer to our eyes. On a very dark background, the reverse is true. If both warm and cool colours are present in a design, generally the warm colours appear to advance whereas the cool ones recede. (Fig. 2c) Colours is used to create an illusion of depth. Generally, intense colours tend to appear closer than do dull colours. Light hues and tints appear closer than darker hues and shades of a colour. Warm and cool colours tend to behave in the same manner. However, this may not always be the case because of the relative characteristics of colour. Fig 2c
  15. 15. d) Change in texture - Coarser textures generally appear closer to our eyes than finer textures. (Fig. 2d) e) Change in view - A form is in full frontal view when Fig 2d it is parallel to the picture plane. If it is not parallel to the picture plane, we can only see it from a slanting angle. Change in view is a result of spatial rotation, creating illusory space though not a very deep one. (Fig. 2e) f) Curving or bending - Flat forms can be curved or Fig 2e bent to suggest illusory space. Curving or bending changes their absolute frontality and affects their diversion from the picture plane. (Fig. 2f) g) Addition of shadow - The addition of a shadow to a Fig 2f form emphasizes the physical existence of the form. The shadow may be cast in front of or behind the form, linked to or detached from it. (Fig 2g) Fig 2g
  16. 16. Volume and Depth in Illusory Space All flat forms can become three-dimensional forms in illusory space with the suggestion of thickness, which just requires supplementary views added to the frontal view. As a threedimensional form is not always seen in full frontality, there are many angles and points of view from which it can be seen and represented on a flat surface convincingly. (Fig. 3a) Fig 3a
  17. 17. There are isometric and other systems of projection in the representation of volume and depth. (Fig. 3b) There are also laws of perspective by means of which we can depict volume and depth with a surprising degree of Fig 3b realism. (Fig. 3c) If we have to represent a cube that has six equal edges meeting each other at right angles, simple systems of projection maintain the equality of the edges and angles to some extent, but perspective which gives a more convincing picture renders most of the equal elements Fig 3c unequal. When a series of cubes is to be represented with one behind another, no decrease in size of the cubes is shown with the various systems of projection, but a gradational decrease in size is shown with perspective. (Fig. 3d) Fig 3d
  18. 18. Plane Representation in Illusory Space Volume is contained by planes which can be represented in various ways: (a) Outlined planes - Planes can be outlined, and the designer may choose any thickness of line for his purpose. Outlined planes in illusory space are usually represented as opaque planes: we cannot see what is behind them. If they are represented as transparent planes, then they may become Fig 4a more like spatial frames. (Fig. 4a) (b) Solid planes - These are planes are without ambiguity. Solid planes, if they are of the same colour, can be used as flat forms to suggest illusory depth, but it is difficult for them to work together to suggest volume. Solid planes with colour variations can effectiveness. (Fig. 4b) represent volume with great Fig 4b
  19. 19. c) Uniformly textured planes - A uniformly textured plane is distinguishable from another which it adjoins or overlaps even if the texture of the two planes is the same. This is because the textural pattern of one plane does not have to spread continuously to the plane adjacent to it. Certain kinds of texture have strong directional feeling which can give emphasis to planes that is not seen frontality but sideways. Densely spaced parallel lines of the same width or regular dot patterns can form textural planes which provide many possibilities for the designer. (Fig. 4c) Fig 4c
  20. 20. d) Gradationally coloured or textured planes Gradationally coloured or textured planes have a different effect in the creation of spatial illusion. They suggest light and shadow patterns or metallic sheens on surfaces, thus enhancing realism to some extent. They are particularly effective in the representation of curved surfaces. (Fig. 4d) Textured planes in perspective should be depicted in such a way that the textural patterns are also seen in perspective. Such textured planes are not uniform but gradational and even radiative (radiating from the vanishing points). Fig 4d
  21. 21. Fluctuating and Conflicting Space Space fluctuates when it appears to advance at moment and recede at another moment. We have already seen a kind of simple fluctuating situation when positive and negative space and reversible figureground relationships was discussed (fig. 5a). Fig 5 a A more dynamic fluctuating situation is illustrated in figure 5b, which can be interpreted either as a shape that is seen from above or as a shape seen from below. Both interpretations are valid. Spatial fluctuation creates interesting optical movements. Fig 5 a M C Escher – Relativity 1953
  22. 22. Conflicting space is similar to fluctuating space yet intrinsically different. Fluctuating space is ambiguous, because there is not a definite way whereby we can interpret the spatial situation, but conflicting space provides an absurd spatial situation which seems impossible for us to interpret. In conflicting space, we feel we are Fig 5c definitely looking down if we only see one part of the design, and we feel we are definitely looking up if we only see another part of the design. However, when the design is seen as a whole, the two visual experiences are in serious conflict with each other and cannot be reconciled. The situation is absurd because it does not exist in reality and can only exist in a two-dimensional space. Somehow it evokes a strange visual tension which offers many interesting possibilities for artists and designers. (Fig. 5c) M C Escher – The Waterfall 1961
