A deformation transformer for real-time cloth animation

Abstract

Achieving interactive performance in cloth animation has significant implications in computer games and other interactive graphics applications. Although much progress has been made, it is still much desired to have real-time high-quality results that well preserve dynamic folds and wrinkles. In this paper, we introduce a hybrid method for real-time cloth animation. It relies on datadriven models to capture the relationship between cloth deformations at two resolutions. Such data-driven models are responsible for transforming low-quality simulated deformations at the low resolution into high-resolution cloth deformations with dynamically introduced fine details. Our data-driven transformation is trained using rotation invariant quantities extracted from the cloth models, and is independent of the simulation technique chosen for the lower resolution model. We have also developed a fast collision detection and handling scheme based on dynamically transformed bounding volumes. All the components in our algorithm can be efficiently implemented on programmable graphics hardware to achieve an overall real-time performance on high-resolution cloth models.

Adaptive anisotropic remeshing for cloth simulation

“…A number of recent cloth simulation techniques fall into this category. Strategies for determining the additional detail include learning from high-resolution simulation data [de Aguiar et al 2010;Feng et al 2010;Wang et al 2010a;Kavan et al 2011], sampling from recordings of real cloth [Popa et al 2009;Hilsmann and Eisert 2012], and directly applying a simplified physical model [Müller and Chentanez 2010;Rohmer et al 2010]. We have observed that the dynamics of fine details can be visually significant and we believe there is utility in simulating fine details directly rather than approximating them.…”

Near-exhaustive precomputation of secondary cloth effects

“…One common approach is to run low resolution simulation and then add extra wrinkle detail based on previously computed highresolution simulations [Wang et al 2010;Kavan et al 2011;Feng et al 2010], recordings of real cloth [Popa et al 2009;Hilsmann and Eisert 2012], or a simplified physical model [Müller and Chentanez 2010;Rohmer et al 2010]. While these approaches dramatically increase cloth realism with minimal computational overhead, the resulting motion can still reflect the low-resolution of the underlying simulation mesh.…”

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].…”
