The purposes of this study are (1) to develop an analysis method and digital tool for finding Visibility characteristics on 3D terrains and (2) to examine their compatibility to actual analysis. Preceding research softwares for space analysis mostly focus on interior spaces and flat exterior areas though a substantial number of recent architectural projects in domestic land are planned at non-flat areas. This study is derived from the proposed incompatibility between the analysis condition and real environment. Theories and technologies of Isovist, NURBS DEM and Algorithmic Script supported the development process. The developed method and computer application measure Visibility Connection, Visibility Connection Ratio, Clustering Coefficient and Control especially essential for evaluating pedestrian circularity and surveillance potential. Also, T-shaped models arranged in various slope directions and a real topographical form were analyzed for testing the performance of the developed. The produced result appears that the analysis method and computer application are applicable to the Visibility Analysis of 3D terrain.
