AR Bending Shell

a Practice of Augmented Reality Building Process

Augmented Reality does not only describe a method where the environment is perceivable and is overlaid with 3D information but also allows to demonstrate complex information on site. With advanced technology, architects can convey digital information to a construction crew. AR Bending Shell utilizes hologram imaging as a guide for the fabrication process of a bending-active linear shell. The Hololens is used as a means to promote a rapid and efficient technique of assembly, one that eliminates custom jigs and fixtures. In this project, the computational generation of form is directly driven and informed by physical behavior and material characteristics. Therefore, the virtual guide is necessary due to the complexity of the design pattern and the nature of the material (PEX pipe).

There are three steps to build a pavilion through the AR method. Based on the material properties, the material-oriented digital model indicates information such as lengths, curvatures, and patterns of components first. Subsequently, the projected 3D design viewed through the Hololens eases the fabrication process and creates a seamless workflow between digital design and physical assemblies, such as real-time 3D simulation of the bending structure, alignment, and positioning of the individual elements, as well as real-time curvature measurements without the use of customized tools. Finally, locating 3D positions on site and erecting the flat pattern made of pipes. Through AR device, the physical model could be adjusted in real-time. This project demonstrates a practice of AR building process.
