Two Architectures: Two Compared Geometries

Abstract

Two very different cities (Berlin and Copenhagen), with two different stories and two different environments, have two different architectures, namely, the Reichstag building in Berlin and the Treetop Experience in Copenhagen, that are differentially designed. Two geometric shapes, an ellipsoid and a hyperboloid of one sheet, are used to interpret the different architectures. A common architectural element in both architectures is a spiral walkway that allows for the buildings’ usability without barriers. In this work, the two observed objects are presented in their respective environment, history and purpose. The shapes are interpreted, which reveals their geometric aspects that are associated with the functional and emotional effects of their architectural forms. Parameterization is the main mathematical tool through which the characteristic shapes are studied and mathematically expressed, using Linear Algebra and the Parametric Geometry of surfaces that are ideally close to the studied architectural objects. Moreover, the free and open-source programming language ASYMPTOTE is used for their virtualization, the model’s reliability is assessed, and the analysis of the model’s behavior is presented.
