OBJECTS in SPATIAL FIELDS -Issues for Design -14

A spatial field is a definable extent of reality, occupied by: Physical elements such as objects, humans and other beings, Non physical things like environmental effects, air, illumination, etc. and Ephemeral presences like relationships, geometries, remembrances.

 The SPATIAL FIELD

The spatial field consists of:

1 changing environmental conditions;

2 elements that are distanced from other elements, and so have potent relationships;

3 elements that are adjacent and so allow comparisons of scale or contrast, and have implicit connections;

4  elements that are partly concealed by other elements covering up the cuts, corners, edges and such other definitive elements, and have characteristic scale and distance;

5 elements obscuring the presence of other elements.

ELEMENTS of SPATIAL FIELD

Spatial field and Environment are perceptible totality. A spatial field is perceived as a static event but the changing environment make it a dynamic happening.Changes are necessary in the spatial fields for us to see anything at all”. Other dynamics include, eye and body movements, changes in surroundings, movement of the objects, and shifting position of the perceiver.

The elements in spatial fields have surfaces with colour and texture. The surfaces also have geometric configurations like convex, concave single or double curvatures. The surfaces have edges at the ends and intermediate breaks. The surfaces, present themselves with inclinations towards or away, in vertical, horizontal and other directions from the perceiver.

The elements in spatial fields have forms. The forms are composed of planes that are representations of solids, pretender fill-in-planes between wire networks, or apparent surfaces that are evident between points. These forms have two distinct qualities: have a gravity-based orientation or references, and are perceived in receding perspective. The second quality is highly dynamic, so offers a taste of reality.

The forms can be of lines, such as in wire-frames, within which the surfaces are presumed to dwell, but without the nominative texture or colour. In such hollowed forms, the shadows of the frames complicate the perception of the holistic form.

The forms in spatial fields are compositions of regular or familiar surfaces, so even a partial reveal can disclose the entireness. Where the forms are of continuously and irregularly varying surfaces, then unless entire form is perceptible or from many directions, its totality cannot be known.

The forms in spatial fields often have orientation of sub-segments that depicts a direction or movement. When such directions are congruent, the form gains a momentum. Similar ‘things’ appear to be grouped together. Alternatively we connect several incoherent elements into a form with dominant theme  of the scene.

Scene building or Spatial narratives commence from parts. One takes in few particular sets, rather than searching for the wholeness. The scene or the narratives get built when cognized sets and our past experiences come together. “We do not just see, but look”. In a spatial field scene building occurs by moving along a predefined path, by shifting the elements and by delaying, hastening or filtering the environmental effects. Designers build scenes or spatial narratives by framing the vista with opportunistic framing, occluding certain sections and by modifying the foreground-background contrasts.

Modelling the Elements in spatial field, is posing of objects and people including own self, to make them noticeable. The process first requires the realization and than corrective measures. For realization one needs to perceive the element from multiple cues, which may be similar to many others, close to each other, interconnected, and part of a complex pattern. The corrective measures include perceptual aggregation of a visual scene. Here the edges, if, are breached, need virtual bridges, to form a larger extent and a perceptible whole.

Structuring a pattern from multiplicity of elements is a process carried out in many different environmental conditions, referencing cues and positions of perception. Regions of space are natural zones, and elements occurring in them seem related. Such regions of space have similar environmental exposure, form, extent, or belong to the same perspective. Patterns replicate a form in many scaled versions, similarity of placement, orientation and contextual relevance.

Silhouettes in a spatial field are the edges or boundaries of forms. Edges distinctly delineate or separate the foreground (from background). Extreme silhouettes emerge when the foreground (the form) is extensive and without any details, and the background is vibrant. The vibrant background helps in bridging the breaks that may exist in the form. Distinguishing the foreground from the background is a task difficult for scenes that fall in visual (cone) of perception. Nominally we perceive dark colour to be a deeper element and the lighter colour to be a nearer one, but with silhouette formation a reversal is forced, creating a myth. Silhouettes in nature (sun-set or sun-rise) are short lasting, so elements with back-lit fields are perceived to be transient.

Familiarity in Spatial field is unexplainable connection. Things that are in a foreground are proximate, and so have the first claim of familiarity. The relevance of purpose offers next level of familiarity. But when other elements in the scene compete in terms of size, orientation or distancing, a dilemma occurs.

Stratification of view in a spatial field occurs at many different scales. Stratification is horizontal sectioning and vertical segmentation, and both aided by situation and architectural elements. A person at the interior edge can view the exterior with movement of head and eyes, but from a depth visual limitation is imposed. Similarly skylights allow unchanging sky view whereas a very tall sill level cuts-off the view of the ground.
