Folding and Crumpling Adaptive Sheets, SIGGRAPH 2013

SIGGRAPH 2013 -- Rahul Narain, Tobias Pfaff, James O'Brien Abstract: We present a technique for simulating plastic deformation in sheets of thin materials, such as crumpled paper, dented metal, and wrinkled cloth. Our simulation uses a framework of adaptive mesh refinement to dynamically align mesh edges with folds and creases. This framework allows efficient modeling of sharp features and avoids bend locking that would be otherwise caused by stiff in-
