Interactive animation of cloth‐like objects in virtual reality

Abstract

Modeling and animation of cloth have experienced important developments in recent years. As a consequence, complex textile models can be used to realistically drape objects or human characters in a fairly efficient way. However, real-time realistic simulation remains a major challenge, even if applications are numerous, from rapid prototyping to ecommerce. In this paper, we present a stable, real-time algorithm for animating cloth-like materials. Using a hybrid explicit/implicit algorithm, we perform fast and stable time integration of a physically based model with rapid collision detection and response, as well as wind or liquid drag effects to enhance realism. We demonstrate our approach through a series of examples in virtual reality environments, proving that real-time animation of cloth, even on low-end computers, is now achievable.

Sensitive couture for interactive garment modeling and editing

“…Mass-spring models generally enable fast and simple computational models for rapid cloth simulation [Meyer et al 2001;Choi and Ko 2002] providing responsiveness at the cost of accuracy and stability. Recent methods have also generated real-time wrinkle synthesis [Rohmer et al 2010], as well as more generally, real-time, data-driven reduced cloth modeling [Feng et al 2010;Wang et al 2010].…”

Target Point Manipulation Inside a Deformable Object

“…A general mass-spring model consists of a set of point masses connected to its neighbors by massless springs. Mass-spring models have been used extensively in facial animation [17], cloth motion [18] and surgical simulation [19]. Howard and Bekey [20] developed a generalized method to model an elastic object with the connections of springs and dampers.…”

Efficient simulation of inextensible cloth

“…While simple to implement, this approach suffers from poor convergence since each displacement may stretch other incident springs. Therefore, Provot's method is used in cases where tight tolerances are not required, e.g., [Desbrun et al 1999;Meyer et al 2001;Fuhrmann et al 2003]. Bridson et al [2002;2003] used Provot's approach in conjunction with strain rate limiting (SRL), bounding the rate of change of spring length per timestep to 10% of the current length.…”
