“Modeling and simulation of sharp creases”
Abstract:
A sharp crease is a unique behavior of a pressed cloth that reveals a fabric specific combination of elasticity and plasticity. It creates a stiff column like ridge along the crease direction, revealing straight lines and breaks. Previous work addressed the wrinkles and creases by manipulating the bending resistance [1,3]. This paper presents a new technique for the realistic animation of sharp creases using a set of hard angle constraints and the implicit constraint scheme for stable and effective constraint enforcement over a large time step.
