Three-dimensional picture pair of a random structure consisting of 50 lines falling at random within a cube. Taken from Noll’s article Computers and the Visual Arts page 9.

" Two perspective drawings obtained from two picture planes and two station points produce what is called a stereographic drawing. Since the two station points are located in slightly different positions, two slightly different perspectives are obtained. When viewed stereoptically. these minute differences in the pictures presented to the left and right eyes are translated by the brain into a depth effect. This figure showsa computer- generated three-dimensional picture pair of a random structure consisting of 50 lines falling at random within a cube. To view the three dimensional effect, place a sheet of paper on edge between the stereo pair. Position your head so that each eye sees only one image. Witha bit of adjustment, the images should seem to converge and appear three-dimensional."
