EFFECTS OF UNFOLDING TECHNIQUES AS DESIGN STIMULI IN BUILDING DESIGN
Through paper folding techniques, i.e. origami, people can make fascinating 3D forms from 2D sheets. Many architects utilise folding techniques in their design process as design stimuli. However, the reverse process, unfolding 3D forms, presents computational geometry problems, and there is limited research that clarifies how designers can use theses unfolding techniques. In this study, we begin by introducing a computational geometry method for generating common developments by unfolding 3D plural cuboids. Next, this paper presents the results of an experiment where extended protocol analysis methods were used to examine the effects of using the unfolding techniques as design stimuli during concept generation. The results show that the unfolding techniques promote creativity in building design and enhance participants' extension of idea space from the microscopic perspective.
