Abstract
Visibility graph analysis (Turner et al., 2001) is widely used for the analysis of architectural space and is linked to pedestrian movement distribution or agent based modeling through a number of studies. However, until now spatial relations associated with a visibility graph were simple, very limited and in most cases sub-sampling the affordances of spatial models in question. In this study we use a newly developed analysis methodology, which we call Augmented Visibility Graph Analysis or AVGA, and is based on mixed-directionality graph structures, in order to study a number of hypothetical architectural designs where visibility, accessibility and permeability challenge the existing tools and methodologies. The paper presents the computational problem of analysing spaces that include 'augmented visibilities', areas with 'inaccessible but visible' locations, and through the case studies it demonstrates how the exclusion of some affordances, of the architectural morphology, from the graph representation can dramatically affect the analysis results. AVGA overcomes the limitations of current visibility graph analysis methodologies and allows the analysis of architectural and urban space that includes visuo-spatial and hybrid configurations past the simple 'wall or opening' restriction. The results show how visuo-morphological relations beyond accessibility can be encoded programmatically and how they can shape our understanding of space through computational models.
