“…Much of the work has been directed towards sheet approximations of cloth [Baraff and Witkin 1998;Bridson et al 2002;Grinspun et al 2003;Goldenthal et al 2007;Volino et al 2009], where the yarn-yarn interactions in fabric are abstracted away and instead treated as aggregate elastic forces on a 2D sheet. Some more recent work has looked at simulating cloth with explicit yarn interactions [Chu 2005;Kaldor et al 2008;Kaldor et al 2010].…”

“…Similar to actual manufacturing processes, sheet-based cloth modelers have often modeled cloth as panels to be sewn together [Carignan et al 1992;Volino and Magnenat-Thalmann 2000;Volino et al 2009]. These initial meshes are then simulated using the sheet-based simulator to generate the relaxed shape of the clothing on a human form with the user making further changes to the initial pattern based on the relaxed result.…”

“…Other research has looked at designing useable interfaces for rapid and intuitive design of new patterns [Volino and Magnenat-Thalmann 2005;Umetani et al 2011]. Researchers have also looked at sketch-based interfaces for designing garments and other 3D objects composed of 2D pieces [Decaudin et al 2006;Turquin et al 2007;Mori and Igarashi 2007;Igarashi et al 2008b;Volino et al 2009;Robson et al 2011]. …”

Figure 1: Stages of our knitted garment modeling system: (a) We begin our interactive modeling process with a polygonal mesh that specifies the global shape of the cloth model; (b) using this polygonal mesh we produce a high-resolution stitch mesh that serves as a canvas-like abstraction of the yarn model; (c) then, we specify the desired knitting pattern over the stitch mesh's surface. (d) Following the interactive modeling process, the model goes through offline relaxation, beginning with a mesh-based relaxation that moves the stitch mesh to the subdivision surface of the input model and slides its vertices over this surface based on the topology of the knitting pattern; finally, (e) we generate the yarn curves and (f) use a physically based relaxation process at the yarn level to compute the final realistic shape. AbstractRecent yarn-based simulation techniques permit realistic and efficient dynamic simulation of knitted clothing, but producing the required yarn-level models remains a challenge. The lack of practical modeling techniques significantly limits the diversity and complexity of knitted garments that can be simulated. We propose a new modeling technique that builds yarn-level models of complex knitted garments for virtual characters. We start with a polygonal model that represents the large-scale surface of the knitted cloth. Using this mesh as an input, our interactive modeling tool produces a finer mesh representing the layout of stitches in the garment, which we call the stitch mesh. By manipulating this mesh and assigning stitch types to its faces, the user can replicate a variety of complicated knitting patterns. The curve model representing the yarn is generated from the stitch mesh, then the final shape is computed by a yarn-level physical simulation that locally relaxes the yarn into realistic shape while preserving global shape of the garment and avoiding "yarn pull-through," thereby producing valid yarn geometry suitable for dynamic simulation. Using our system, we can efficiently create yarn-level models of knitted clothing with a rich variety of patterns that would be completely impractical to model using traditional techniques. We show a variety of example knitting patterns and full-scale garments produced using our system.

“…The usual StVK CST element, when it is compressed, can induce instability [Volino et al 2009], because its force Jacobian becomes indefinite. Similar to Teran et al [2005], when the element is in a compressed configuration, we adjust the Jacobian entries to eliminate negative eigenvalues.…”

Figure 1: "2D or not 2D?" This timeless question is rendered moot by Sensitive Couture, our tool for simultaneous, synchronized modeling and editing of both a 2D garment pattern (top) and its corresponding 3D drape (bottom). AbstractWe present a novel interactive tool for garment design that enables, for the first time, interactive bidirectional editing between 2D patterns and 3D high-fidelity simulated draped forms. This provides a continuous, interactive, and natural design modality in which 2D and 3D representations are simultaneously visible and seamlessly maintain correspondence. Artists can now interactively edit 2D pattern designs and immediately obtain stable accurate feedback online, thus enabling rapid prototyping and an intuitive understanding of complex drape form.

“…With the development of computer hardware and graphics, the physical method which has a better reality based on Newton's law of motion becomes the mainstream. Physical method has developed a continuum model [3,4] and discrete particle model [5]. Because the discrete particle model uses the relatively simple mechanical form to describe the dynamic characteristics of cloth deformation, the computational complexity is very low, which makes the method performs better in real-time than the continuum model.…”

Abstract-In order to solve the problem that the adjustment sequence depends only on the data structure in the process of constraint satisfaction, a method of propagating from the fixed points is proposed. The method analyzes the internal force of fabrics in the real world, sorts the particles in ascending order according to the distance from the mass to the fixed points by using the breadth-first search method. The experimental results show that applying the proposed method to the position based dynamics simulation of cloth can converge faster and improve the simulation efficiency.
