  text: Triangle mesh-based simulations are able to produce satisfying animations
    of knitted and woven cloth; however, they lack the rich geometric detail of yarn-level
    simulations. Naive texturing approaches do not consider yarn-level physics, while
    full yarn-level simulations may become prohibitively expensive for large garments.
    We propose a method to animate yarn-level cloth geometry on top of an underlying
    deforming mesh in a mechanics-aware fashion. Using triangle strains to interpolate
    precomputed yarn geometry, we are able to reproduce effects such as knit loops
    tightening under stretching. In combination with precomputed mesh animation or
    real-time mesh simulation, our method is able to animate yarn-level cloth in real-time
    at large scales.

  text: Photorealistic editing of head portraits is a challenging task as humans are
    very sensitive to inconsistencies in faces. We present an approach for high-quality
    intuitive editing of the camera viewpoint and scene illumination (parameterised
    with an environment map) in a portrait image. This requires our method to capture
    and control the full reflectance field of the person in the image. Most editing
    approaches rely on supervised learning using training data captured with setups
    such as light and camera stages. Such datasets are expensive to acquire, not readily
    available and do not capture all the rich variations of in-the-wild portrait images.
    In addition, most supervised approaches only focus on relighting, and do not allow
    camera viewpoint editing. Thus, they only capture and control a subset of the
    reflectance field. Recently, portrait editing has been demonstrated by operating
    in the generative model space of StyleGAN. While such approaches do not require
    direct supervision, there is a significant loss of quality when compared to the
    supervised approaches. In this paper, we present a method which learns from limited
    supervised training data. The training images only include people in a fixed neutral
    expression with eyes closed, without much hair or background variations. Each
    person is captured under 150 one-light-at-a-time conditions and under 8 camera
    poses. Instead of training directly in the image space, we design a supervised
    problem which learns transformations in the latent space of StyleGAN. This combines
    the best of supervised learning and generative adversarial modeling. We show that
    the StyleGAN prior allows for generalisation to different expressions, hairstyles
    and backgrounds. This produces high-quality photorealistic results for in-the-wild
    images and significantly outperforms existing methods. Our approach can edit the
    illumination and pose simultaneously, and runs at interactive rates.

  text: Material appearance hinges on material reflectance properties but also surface
    geometry and illumination. The unlimited number of potential combinations between
    these factors makes understanding and predicting material appearance a very challenging
    task. In this work, we collect a large-scale dataset of perceptual ratings of
    appearance attributes with more than 215,680 responses for 42,120 distinct combinations
    of material, shape, and illumination. The goal of this dataset is twofold. First,
    we analyze for the first time the effects of illumination and geometry in material
    perception across such a large collection of varied appearances. We connect our
    findings to those of the literature, discussing how previous knowledge generalizes
    across very diverse materials, shapes, and illuminations. Second, we use the collected
    dataset to train a deep learning architecture for predicting perceptual attributes
    that correlate with human judgments. We demonstrate the consistent and robust
    behavior of our predictor in various challenging scenarios, which, for the first
    time, enables estimating perceived material attributes from general 2D images.
    Since our predictor relies on the final appearance in an image, it can compare
    appearance properties across different geometries and illumination conditions.
    Finally, we demonstrate several applications that use our predictor, including
    appearance reproduction using 3D printing, BRDF editing by integrating our predictor
    in a differentiable renderer, illumination design, or material recommendations
    for scene design.

  text: Previous research on animations of soap bubbles, films, and foams largely
    focuses on the motion and geometric shape of the bubble surface. These works neglect
    the evolution of the bubble’s thickness, which is normally responsible for visual
    phenomena like surface vortices, Newton’s interference patterns, capillary waves,
    and deformation-dependent rupturing of films in a foam. In this paper, we model
    these natural phenomena by introducing the film thickness as a reduced degree
    of freedom in the Navier-Stokes equations and deriving their equations of motion.
    We discretize the equations on a nonmanifold triangle mesh surface and couple
    it to an existing bubble solver. In doing so, we also introduce an incompressible
    fluid solver for 2.5D films and a novel advection algorithm for convecting fields
    across non-manifold surface junctions. Our simulations enhance state-of-the-art
    bubble solvers with additional effects caused by convection, rippling, draining,
    and evaporation of the thin film.

  text: 'We present a method for animating yarn-level cloth effects using a thin-shell
    solver. We accomplish this through numerical homogenization: we first use a large
    number of yarn-level simulations to build a model of the potential energy density
    of the cloth, and then use this energy density function to compute forces in a
    thin shell simulator. We model several yarn-based materials, including both woven
    and knitted fabrics. Our model faithfully reproduces expected effects like the
    stiffness of woven fabrics, and the highly deformable nature and anisotropy of
    knitted fabrics. Our approach does not require any real-world experiments nor
    measurements; because the method is based entirely on simulations, it can generate
    entirely new material models quickly, without the need for testing apparatuses
    or human intervention. We provide data-driven models of several woven and knitted
    fabrics, which can be used for efficient simulation with an off-the-shelf cloth
    solver.'

  text: We propose a method to enhance the visual detail of a water surface simulation.
    Our method works as a post-processing step which takes a simulation as input and
    increases its apparent resolution by simulating many detailed Lagrangian water
    waves on top of it. We extend linear water wave theory to work in non-planar domains
    which deform over time, and we discretize the theory using Lagrangian wave packets
    attached to spline curves. The method is numerically stable and trivially parallelizable,
    and it produces high frequency ripples with dispersive wave-like behaviors customized
    to the underlying fluid simulation.
