Carrying on from the post on Classical Geometries in architecture, this post collects some of the contemporary computational geometries in architecture:

CONTEMPORARY AND PARAMETRIC GEOMETRIES IN ARCHITECTURE

Carrying on from the previous list of historical geometries in architecture, it’s time to look into contemporary geometry typologies. These increasingly depend on mathematics and scientific theories like Systems Thinking, but the list below does not go into these in detail but will give you a broad overview of some of the concepts.

Parametric Geometries

CARTESIAN COORDINATION SYSTEM

The 17th century also saw the invention of a method to describe forms in a 2 or 3-dimensional space using numerical coordinates. Starting at an origin point, (in 3D) three mutually perpendicular axis (x, y and z) form a three-dimensional numerical grid. The combination of topology, vectors, and the co-ordinates are the basis of any Computer Aided Design space.

Parametric geometry

CALCULUS TO TOPOLOGY

In the 17th century Calculus, the mathematical study of continuous change, leads to new evaluation of forms and form calculation.

Topology is distinct from geometry within mathematics. Topology engages in the properties of geometric objects with continuous deformations, such as pulling, pushing, twisting, stretching, crumpling and bending, but not assembling, stacking, cutting or adhering like classical geometries.

Spline control

SPLINE

Originally a long thin strip of wood used by boat builders to draw smooth shapes. A spline is at its core a polynomial line controlled by variable points. The curve does not have a uniformly straight or circular segments as each segment between control points will be affected by points beyond the immediate control points. For this reason, splines and spline-based surfaces are considered by many as the fundamental parametric design language.

Single Surface Geometry

SINGLE SURFACE

The Möbius strip has been mentioned before as a classical geometry. This is a simple ruled geometry where a strip of 2D surface is joined into a continual rotated surface. A surface that is effectively one sided. Klein bottle is the 3-Dimensional version of the same mathematical concept. The idea of single surfaces has been prevalent in parametric design approaches with attempts at breaking down clear distinctions between building elements (wall, floor, ceiling etc.)

The geometry in architecture is an essential parts for designing a strong structure scientifically. Being a architecture designer, I have learned something about geometries in architecture from online discussion platform such as this website. But currently, I have been performing as a manager director at Chatroulette Italiana site and help people with video chat facilities for the adult group of people. By the way, I appreciate your efforts on writing this wonderful post on geometries in architecture.

Parametrische Formen sind das Herzstück der Archimatix-Modellierung. Ein Großteil der Formenerzeugung in der realen Architektur wird durch Formen bestimmt, die dann extrudiert, gepfeilt und wiederholt werden. In diesem Sinne sind architektonische Formen eine Abkehr von skulpturalen Formen wie organischen Körpern, Automobilformen oder geologischen Formationen, die eher topologischer Natur sind und am besten mit 3D-Booleans und Bildhauerwerkzeugen aus Maya und ZBrush modelliert werden. Ein Großteil der Architektur hingegen lässt sich mit Grundriss- und Schnittformen digital beschreiben. In Archimatix sind Pläne und Schnitte normalerweise parametrische Formen. Ich mag diese Studie, da sie mir bei der Gestaltung dieser Website geholfen hat.
