Crosswise Recursive Algorithm of Optimized Wrinkling for Quadric Surface Metal Curtain Wall

Metal curtain walls have been used to decorate the interiors and exteriors of large buildings. Most exteriors used in performing surface modeling of large buildings are linked or pieced by quadric surface. This surface, which is non-expansible, will cause wrinkling when stamped and used as a flat sheet metal of a metal curtain wall. These wrinklings are not distributed effectively because of the curvature asymmetry of surface modeling. Hence, this study proposes a horizontal recursive algorithm of optimized wrinkling that will enable effective distribution of wrinklings when the surface is stamped to form a shape, thereby satisfying the requirements of precision in surface stamping.
