Curved glass fa\u00e7ades can be stunningly beautiful, but traditional construction methods are extremely expensive. Panes are usually made with ‘hot bending,’ where glass is heated and formed using a mold or specialized machines, an energy-intensive process that generates excess waste in the form of individual molds. Cold-bent glass is a cheaper alternative in which flat panes of glass are bent and fixed to frames at the construction site. However, given the fragility of the material, coming up with a form that is both aesthetically pleasing and manufacturable is extremely challenging. Now, an interactive, data-driven design tool allows architects to do just that.<\/p>\n

Created by a team of scientists from IST Austria, TU Wien, UJRC, and KAUST, the software allows users to interactively manipulate a fa\u00e7ade design and receive immedia<\/a>te feedback on the fabricability and aesthetics of the panelization\u2014-a very convenient way for navigating various realizations of the designer’s intentions. The software is based on a deep neural network trained on special physical simulations to predict glass panel shapes and fabricability. In addition to allowing users to interactively adapt an intended design, it can automatically optimize a given design, and can be easily integrated into an architect’s usual workflow. The software and research results were presented at SIGGRAPH Asia 2020.<\/p>\n

Hot-bent and cold-bent glass<\/b><\/p>\n

Hot-bent glass has been in use since the 19th century, though it was not until the 1990s that it became general<\/a>ly available. Still, the process remains prohibitively expensive and the logistics of transporting bent glass are complicated. An alternative, cold-bent glass, was developed around ten years ago. It was cheap to make, easy to transport, and the geometric and visual quality were better than hot-bent glass. The technique also allowed architects to make use of special types of glass and accurately estimate the deformation stress on the panels.<\/p>\n

The issue was that designing cold-bent glass fa\u00e7ades represents an enormous computational problem. Ruslan Guseinov, IST Austria postdoc and co-first author, explains: “While it is possible to calculate when an individual panel will break, or provide a safety margin for additional loads, working with the full fa\u00e7ade\u2014-which often comprises thousands of panels\u2014-is simply too complex for the conventional designer tools.” Moreover, using a computer with traditional computational methods to obtain stresses and shapes each time a change was made would take too long to be usable.<\/p>\n
