This paper presents and briefly describes VISSOP, a visibility-based analysis application dedicated to space syntax methodologies. It has been developed as a set of custom Operator Type Library (OTL) modules, within the Surface Operator (SOP) and geometry context of SideFX Houdini. VISSOP allows to perform two- and three-dimensional visibility-based analyses with high precession and performance. The focus of VISSOP is on the analysis of architectural interior space in order to investigate the relationship between the geometric shape and visual appearance of space and human experience and behavior. To achieve this, it combines geometrical, topological, and image-based methods to calculate a large number of quantitative measures as proposed by various authors in the space syntax literature. In order to take important visual properties such as light and color into account, VISSOP utilizes lightmap and texture baking techniques, as well as saliency detection models from the field of computer vision.
