![]() Projected and Unprojected Surfaces in a Stationary Optic Array These departures from mere background – layout always involve an occluding edge. In solid geometry, a detachqable object is a topologically “closed” surface an aperture is a topologically closed “hole” through a surface or object. However, the environmental layout always in fact includes things like “u>detachable objects, or apertures, or ells in a wall, or cliffs, or overhangs. Like the earth, an enclosed space such as a bare room with floor, walls, and ceiling but without furnishing entials merely these same gradients of texture along with abrupt changes of gradient where the changes of slant of the surfaces occur - the “corners” (Fig. The cloudless sky contains no texture and no gradients. The ambient light from a theoretically bare earth entiails merely decreasing angular size of the optical texture with increasing distance out to the horizon (Figure 9.2 in Senses Considered). There will only be unbroken gradients of the density of optical texture, or tuxture perspective. We note first that an environment consisting only of flat “ground” or “background” will not manifest any kind of occlusion. Surface layouts that do and do not involve occlusion. What are the principles of static and kinetic occlusion?ġ. We should note, however, that the static array is an almost unrealized limiting case, since a human or animal observer is never frozen at a single station point for any length of time, and a completely frozen environment is a fixtion. We should consider both stationary occlusion for a static array and kinetic occlusion for an array containing “motions” (see figure). The “sight-lines” in the cross-sectional diagram herewith illustrate these principles. ![]() This is an extension of the previous Cornell efforts to describe such “motions and transformations.” The stationary structure of ambient light is fairly familiar to us because we know about the “law of the visual angle,” and the “laws of perspective.” The kinetic structure, however, if the term be allowed, is much less familiar.Ĭonsider the principles of optical occlusion, that is, the hiding, covering, superposition, or screening of one thing by another. The possible kinds of “motion” in an optic array have not been fully described only a start has been made (e.g. There is always more information (in the sense of less ambiguous information) in a kinetic array than in a static array. By this I mean what are vaguely called the “motions” in an optic array, arising from either the movements of the observer himself (motion parallax) or the motions of an object in the world. 11) and what might be called its kinetic structure. 208-220) so as to understand the information contained in the light.Īn important problem is to distinguish between the stationary structure of ambient light, as exemplified in the perspectives of an ordinary pictorial array (ch. 187-208 in The Senses Considered as Perceptual Systems) and to try and establish the usual environmental causes of this structure (p. The task of “ecological” optics is to formulate the principles of structure in the ambient optic array from the environment (p. Copies may be circulated if this statement is included on each copy.
