Abstract

The most common technique for making panels resulting from complex geometries from irregular architectural surfaces feasible has been tessellation. This polygon splitting technique enables the execution of panels for facades, space structures, brises, decorative elements, etc. The division aims at forming flat pieces, without aesthetic distortions and with a relative loss of smoothness in the initial formation. This division cannot be arbitrary, since the set of forms should preferably be within a finite number and more easily determined. The following tests are performed: study of the initial tessellation approach, discretizing operation, Gaussian analysis, optimizing operation and, finally, legitimizing the result. These operations make it possible to construct the irregular architectural shape (variable in relation to the scale) by simplifying geometric shapes at very specific levels. The research results show reflections in order to make the construction of complex surfaces feasible, organizing the subdivision in stages to ensure satisfactory feasibility: ease of execution of parts, handling and transportation logistics, compatibility between the structure and the seal, execution on site.


Keywords: subdivision surfaces, constructive adequacy, freeform surfaces.

Fábio Lima, Universidade Federal de Goiás

Doutor em Arquitetura e Urbanismo, UNB (2015), mestre em Cultura Visual, UFG (2006), bacharel em Arquitetura e Urbanismo, UCG (2000). É professor adjunto na FAV/UFG, com experiência na área de Comunicação Visual e Projetos de Arquitetura, ocupando as disciplinas de Projeto na Arquitetura e Urbanismo, Processos de Criação e Fabricação Digital e Informática Aplicada à Arquitetura e Urbanismo. Investiga os recursos das novas tecnologias que vem sendo utilizadas na produção da arquitetura e urbanismo contemporâneos, dos problemas que envolvem a construção das linguagens formais, suas representações, e suas respectivas inserções sociais e culturais. As pesquisas se enveredam também nos processos de projeto, as distintas soluções plásticas, estruturais e funcionais que vem sendo dadas a um grande número de edificações complexas, assim como suas várias relações com outras áreas do conhecimento humano.
