We evaluated the relationship between spatial layout and a range of social, economic, and environmental phenomena in the castle district of Daegu by using space syntax theory. The results are as follows : 1) In 1920, the topological center of the street network was concentrated in the northern area of the district and spread towards the southern area in 2009. 2) Winding alleys has been reduced, and the topological depth in the castle district became more shallow from 1920 to 2009.3) The configuration characteristics of the street network is related to the composition of the buildings and land use in the castle district of Daegu, which we determined from the results of a correlation analysis.

A pair of two perspective views of an object called as stereopair reproduces an image without distortion called cardboard effect or puppet theater effect only when the left-side view and the right-side one are observed from each center of perspective projection just separated horizontally by observer’s interocular distance. Then, the virtual location and form of the reproduced image are same with the actual location and form of the original object regardless of location of screen on which the stereo-pair is projected. As a stereoscopic television is assumed to be observed from three time’s far of height of the screen, each shape of the left-side view or the right-side one on any screen is similar respectively and the parallax between the left.side view and the right-side one is different according to the location of the screen. Appropriate parallax to reduce the load of observer’s eyes should determine the optimum location on a screen. Descriptive geometrical constructions show that a stereoscopic television should be equipped with the screen which has the same width and height to reproduce 3D.images without distortion.
