Nowadays, smooth, curved surfaces are very common in architectural solutions, and proper design of repetitive patterns on such surfaces is a real challenge for architects and designers. This paper presents various algorithmic approaches to pattern design and distribution, based on examples of existing solutions and on the authors’ designed algorithms and didactic experiences. Algorithmic studies are based on Rhinoceros for NURBS (Non-Uniform B-Spline) modelling and on the Grasshopper plugin for graphic algorithm editing. This approach to the topic combines geometry, aesthetics, flexibility and IT techniques, that are very useful in case of pattern distribution. The examples present algorithms that help in clear definitions and the realization of the designer’s intentions to achieve accurate results. KEYWORDS: pattern, surface, mapping, tessellation.
In this paper, the authors test genetic algorithms as geometric and design issues’ solvers to explain and explore the possibilities of this computing technique in design and research. The tests and explanations are based on three classical geometry problems of the Ancient Greece and on a pattern distribution algorithm, created by the authors and inspired by the definition of Lebesgue covering dimension. The basic tools for research are: Rhinoceros, the Grasshopper plug-in and the Galapagos tool. The tests prove that, as a result based on computing techniques, genetic algorithms can be used to find solutions without the implementation of analytic methods. This advantage of evolutionary computing can be very useful in case of complex issues, where implementation of analytic methods reveals itself difficult or even impossible.
The relationship between cultural and geographic parameters in algorithmic design -sample algorithm Zależność między parametrami kulturowymii geograficznymi w projektowaniu algorytmicznym -przykładowy algorytm
AbstractThe article presents selected issues related to the role of cultural and geographic parameters in architectural and urban design. The author defines the groups of parameters and analyses a relationship between them and its influence on design process. The relationship between the groups of parameters is presented at the example of evolutionary algorithm that searches for proper location for Roman military camp. Presented algorithm is an example of possible usage of the relationship between the groups of parameters in modern algorithmic design where cultural factors are used for evaluation of geographic parameters.
Keywords: cultural and geographic parameters, algorithmic designStreszczenie Artykuł przedstawia wybrane zagadnienia związane ze znaczeniem parametrów kulturowych i geograficznych w projektowaniu architektonicznym i urbanistycznym. Autor definiuje grupy parametrów oraz analizuje zachodzącą między nimi zależność i jej wpływ na proces projektowania. Relacja pomiędzy grupami parametrów została przedstawiona na przykładzie algorytmu poszukującego lokalizacji dla historycznego obozu rzymskiego. Prezentowany algorytm jest przykładem możliwości zastosowania zależności pomiędzy grupami parametrów we współczesnym projektowaniu algorytmicznym, gdzie czynniki kulturowe mogą zostać wykorzystane w celu ewaluacji parametrów geograficznych Słowa kluczowe: parametry kulturowe i geograficzne, projektowanie algorytmiczne
