In this work, we demonstrate that quad-edge mesh data structure can efficiently be used to construct large shapes. We have developed a system to unfold any polygonal mesh based on quad-edge structure. Using our system, any shape can be constructed by using laser-cut developable panels. This approach is particularly suitable to construct complicated sculptural and architectural shapes from anisotropic materials that can only be bent in one direction. (C) 2016 Elsevier Ltd.
