Some factors affecting the perception of space between forms
In creating a convincing sense of recession, diminution and the sense of distance between forms a combination of factors is required. (See Kenneth R. Adams, ‘Perspective and the Viewpoint,’ Leonardo, Vol., 5, 1972, pp. 209–17, partic. pp. 209–10. My list is an expansion of Adams’s.) Convergence of orthogonals to a central point and the Albertian diagram (Fig. 118) to control diminution are but two of these. Obviously, not all of these are necessary to a particular image. The presence of human figures is a precondition.
The following is a list of these factors.
1 View through a ‘window’ or frame.
2 Base of ‘window’ (as minimum) aligned with floor.
3 Masking and overlapping.
4 Figures inhabiting buildings/landscape.
5 Partial views of buildings.
6 Convincing massiveness of buildings/landscape.
7 Geometric perspective:
i orthogonal convergence to a point.
ii figures in scale with buildings/surroundings.
iii geometrically controlled diminution.
8 Foreshortening of figures and parts of figures; simple anamorphosis.
9 Light and shade.
10 Atmospheric perspective.
11 Graduated levels of relief (sculpture only).
12 Binocular parallax (sculpture only).
13 Movement parallax – actual (relief sculpture) or implied (painting).
