Tree Facades: Generative Modelling with an Axial Branch Rewritting System
MetadataShow full item record
The methods and algorithms of generative modelling can be improved when representing organic structures by the study of computational models of natural processes and their application to architectural design. In this paper, we present a study of the generation of branching structures and their application to the development of facade support systems. We investigate two types of branching structures, a recursive bifurcation model and an axial tree based L-system for the generation of facades. The aim of the paper is to capture not only the form but also the underlying principals of biomimicry found in branching. This is then tested, by their application to develop experimental facade suport systems. The developed algorithms implement parametric variations for facade generation based on natural tree-like branching. The benefits of such a model are: ease of structural optimization, variations of support and digital fabrication of facade components.

Design exploration with stochastic models of variation: Comparing two examples from facade subdivisionDatta, Sambit (2013)The imitation of natural processes in architectural design is a long-standing area of research in computational design. The approach of “directed randomness” permits the stochastic exploration of a vast space of design ...
Tan, Ben Hoea; Lucey, Anthony; Pitman, Mark (2011)Nowadays modern high-rise buildings have unique facades which partly rely on the incorporation of curtain walls. A curtain-wall system encloses the building to separate the internal and external environments. It can reduce ...
Haemodynamic evaluation of coronary artery plaques : prediction of coronary atherosclerosis and disease progressionChaichana, Thanapong (2012)Coronary artery disease is the leading cause of death in advanced countries. Coronary artery disease tends to develop at locations where disturbed flow patterns occur, such as the left coronary artery. Haemodynamic change ...
