Surface rationalization reducing curvatures, clustering panels, while keeping edge continuity
Free form glass panel optimization.
Free-form shapes need doubly curved glass panels which are all different and very expensive. Using a two-stage optimization algorithm, we first reduce the curvature of the panels and then cluster them to reduce the number of moulds necessary to produce them, reducing costs and wastage.
