Among the analysis methods of spatial structure, qualitative method
adopts personal experience or opinion while quantitative one adopts
surveyed data as ground of argument.
Recent research has shown tendency to move from qualitative one
to the other and in western countries, this inclination have appeared
distinctively, especially in Britain and Germany.
Quantitative analysis could be suggested as a method to prove
description or opinion on architectural space scientifically in analyzing architectural spatial structure. Therefore, this study proposes a
method able to quantify the variance of a spatial experiencer's visual
spatial experience according to position and movement of him and
develops a computer program as a new analyzing implement used to
assay the spatial visual structure easily and rapidly. This computer
program is carried out on visible area, visible limited line and spatial
releasavity, and then calculates their variable numbers and finally
graphicalizes them. Using these functions, analysis of existing samples
could confirm this analysis method's value and practicality.
Investigation on treaties, proposal of algorithm, computer programming
and analysis of examples have been carried out to achieve this study.
In architectural field, perception of space is broad concept includes
the idea and appraisement of spatial cognition influenced through the
sense-organs. The real value of being could be found in the interaction
between building and perception of human. Among the senses of
human, the sight is the most important factor and the spatial concept
is subordinated or maintained to visual image. Every complex,
separate sense of human is connected to visual structure strongly; it
could be convicted by visual figure and translated by approach in the
method of visual structure. In addition, vision has an advantage that it
is quite uncomplicated to quantify and predictable its result.
Sight is the result of light. Light has the nature to stretch illimitably;
therefore, in order to quantify the sight, the boundary of space should
be set and in this study, the spatial structure is basically quantified
and analyzed in this boundary. Furthermore, the emotion to visual
environment element of observer’s is ignored.
Spatial visible area is an aggregate of all point in visible boundary from viewing point, and the ratio, which a certain convex space has
got in the whole area, could be analyzed by visible-area-variablenumber,
and the shape and the route could also be analyzed by its
visible area graph.
Visible limited variable number is calculated by the ratio of length of
the around of visible area and the sum of visible limited line. Through
this analysis of visible limited line, the visional relation ratio between a
certain convex space and its neighbor could be shown quantitatively.
We could understand the visional connection ratio with the neighbor
convex space by spatial releasavity obtained from the angle of visional
opening and viewing point of certain viewing point. The size of release
angle, whose direction could be analyzed by spatial releasavity vector,
could be obtained by spatial releasavity variable number.
A computer program, activated in AutoCad R14 and developed in
ARX file, is developed to improve the reliability of variable numbers
and to be adopted for practical and rapid analysis. It figures
automatically visible area map and spatial releasavity map, and
calculates visible area variable number, visible limited variable number
and spatial releasavity variable number by selecting its boundary,
visible environmental element and viewing point.
The numbers suggested in quantitative manner, achieve variable
analysis by associating with number of static programs, and with
programs such as word process, graphical editing one, it simulates its
results straightforwardly. Quantitative analysis analyzes and figures
spatial physical structure, and by adopting mathematical concept for
objective and computerized analysis, the result could be substantiated. However, it could not explain every element, therefore, interacted
analysis with qualitative method needs to be adopted.
In this study, the worth and the denotation of setting quantitative
spatial analysis implement and its usability have been studied. This
might be the small start; hence, more quantitative analysis method,
includes 3 dimensional visional structure analyses, should be studied
