Surface-based cloth appearance models have been rapidly advancing, shifting from detail-less BRDFs to modern per-point shading models with accurate spatially-varying reflection, transmission, and so on. However, the increased complexity has brought ...

We present a method to improve the computation time of thin shell simulations by using adaptive rigidification to reduce the number of degrees of freedom. Our method uses a discretization independent metric for bending rates, and we derive a membrane ...

We present a general framework for the garment animation problem through unsupervised deep learning inspired in physically based simulation. Existing trends in the literature already explore this possibility. Nonetheless, these approaches do not handle ...

DreamWorks Animation’s The Boss Baby : Family Business has a strong design language. Clothing is an essential part of characterization we needed to maintain strong graphic silhouettes on garments. The characters love changing clothes pretty frequently. ...

Seams play a fundamental role in the way a garment looks, fits, feels and behaves. Seams can have very different shapes and mechanical properties depending on how fabric is overlapped, folded and stitched together, with garment designers often choosing ...

Regularization is used to avoid overfitting when training a neural network; unfortunately, this reduces the attainable level of detail hindering the ability to capture high-frequency information present in the training data. Even though various ...

The Human World of Soul takes place in a vibrant New York City, full of life, energy, and everyday people. Our character designers captured this in their expressive drawings, depicting clothing in a complex and artfully messy way. When creating ...

In Walt Disney Animation Studios’ “Raya and the Last Dragon”, the fantasy world of Kumandra is composed of five lands, representing five parts of a dragon. All aspects of the character designs were inspired by the many cultures of Southeast Asia. Each ...

The material point method (MPM) recently demonstrated its efficacy at simulating many materials and the coupling between them on a massive scale. However, in scenarios containing debris, MPM manifests more dissipation and numerical viscosity than ...

This paper introduces a method to simulate complex rod assemblies and stacked layers with implicit contact handling, through Eulerian-on-Lagrangian (EoL) discretizations. Previous EoL methods fail to handle such complex situations, due to ubiquitous and ...

Photorealistic and physically-based rendering of real-world environments with high fidelity materials is important to a range of applications, including special effects, architectural modelling, cultural heritage, computer games, automotive design, and ...

Costumes are an important part of character design, acting, storytelling, and visual appeal in animation. However, it is challenging to achieve art-directed natural-looking motion and detail in CG animated clothing, due to technology, workflow, and ...

We present a novel method for simulation of thin shells with frictional contact using a combination of the Material Point Method (MPM) and subdivision finite elements. The shell kinematics are assumed to follow a continuum shell model which is ...

We resolve the longstanding problem of simulating the contact-mediated interaction of cloth and sharp geometric features by introducing an Eulerian-on-Lagrangian (EOL) approach to cloth simulation. Unlike traditional Lagrangian approaches to cloth ...

Rendering fabrics using micro-appearance models---fiber-level microgeometry coupled with a fiber scattering model---can take hours per frame. We present a fast, precomputation-based algorithm for rendering both single and multiple scattering in fabrics ...

Currently, rendering systems are able to produce photorealistic simulations of the appearance of many real-world materials. In the real world, viewer perception of objects depends on the lighting and object/material/surface characteristics, the way a ...

Here we introduce our system Textile++, a touch-sensitive cloth consisting of fiber materials. With this system, it is possible to detect the XY coordinate position of the substance touching the cloth. In addition, pressure can be detected. Textile++ is ...

Accurate estimation of mechanical parameters for simulation of woven fabrics is essential in many fields. To facilitate this we first present a new orthotropic hyperelastic constitutive model for woven fabrics. Next, we design an experimental protocol ...

As has been noted and discussed by various authors, numerical simulations of deformable bodies often adversely suffer from so-called "locking" artifacts. We illustrate that the "locking" of out-of-plane bending motion that results from even an edge-...
