展開図からの造形-単曲面立体の形成- FORMATION FROM DEVELOPMENT PATTERNS
In general, when developing a round solid such as a sphere, there are three wellknown ways of doing so. The zone method cuts the surface of the sphere in a holizontal parallel line ; the meridian method vertically cuts the sphere through the poles the triangular method develops the sphere by considering its surface as a triangular mass. Based on these methods, this study attempts to classify the development structures which are led from various development patterns of a regular dodecahedron, and form solids using simple curved surfaces according to each development structure. Six development structures are selected as typical examples. a) is Horizontal development structure, b) is Vertical development structure, c) is Inclined development structure, d) is Spiral development structure, e) is Reticulate development structure, f) is Wave-like development structure. Many other expression are hidden in the transformation process from multi - curved to single curved surfaces. Various development patterns may be obtained from a single model. The formation of an object from a development pattern may differ in image according to the development method.
