Convex and Solid-Voids



isometric diagram showing the step by step generation of the street void

Top Left: the outlines of Convex Spaces defined by the division of the topography surface based on vertical boundary facades. Top Center: Boundary Faces Top Right: Convex Voids (heights determined by surrounding facade heights and neighboring CVs). Bottom Left: Flows Bottom Center: Solid-Voids generated by the aggregation of Convex Voids based on vertical and horizontal continuity of paths. Bottom Right: Street-Voids, generated by the aggregation of Convex Voids based on street center lines.



Here we further explain the method and the meanings of the attributes we use in the analysis of the IBX corridor study.

The Convex and Solid Void  methodology was developed at the Design Computing Lab of the Faculty of Architecture, University of Lisbon by Prof. Jose Beirao, Dr. Ljiljana Cavic and Dr.Rusne Sileryte. Rui de Clerk, Joao Neves and Elif Ensari worked on the advancement of the method and expanded its domain of application. See for more information.
