Perceiving Architectural Space: From Optic Arrays to lsovists
Imagine a rectangle (representing a room) and the space within it. Draw a straight line between any two points on the rectangle; draw another, and another, until the space of the rectangle is effectively filled with criss-crossing lines between all pairs of points. Now choose any point within the rectangle and you find that a large nu mber of lines pass through that point , one of which is shared with another different set of lines pass ing through a point nearby . If we consider these lines to represent light rays (i. e ., photon streams) of varying wavelength and intensity be ing scattered and bounced by the edges of the rectangle (i.e., the walls of the room) , then you have a picture of an optic array-a set of rays that happens to pass through the point of interest.
