  text: We present a data-driven technique to instantly predict how fluid flows around
    various three-dimensional objects. Such simulation is useful for computational
    fabrication and engineering, but is usually computationally expensive since it
    requires solving the Navier-Stokes equation for many time steps. To accelerate
    the process, we propose a machine learning framework which predicts aerodynamic
    forces and velocity and pressure fields given a threedimensional shape input.
    Handling detailed free-form three-dimensional shapes in a data-driven framework
    is challenging because machine learning approaches usually require a consistent
    parametrization of input and output. We present a novel PolyCube maps-based parametrization
    that can be computed for three-dimensional shapes at interactive rates. This allows
    us to efficiently learn the nonlinear response of the flow using a Gaussian process
    regression. We demonstrate the effectiveness of our approach for the interactive
    design and optimization of a car body.

  text: 'Spinning tops and yo-yos have long fascinated cultures around the world with
    their unexpected, graceful motions that seemingly elude gravity. Yet, due to the
    exceeding difficulty of creating stably spinning objects of asymmetric shape in
    a manual trial-and-error process, there has been little departure from rotationally
    symmetric designs. With modern 3D printing technologies, however, we can manufacture
    shapes of almost unbounded complexity at the press of a button, shifting this
    design complexity toward computation. In this article, we describe an algorithm
    to generate designs for spinning objects by optimizing their mass distribution:
    as input, the user provides a solid 3D model and a desired axis of rotation. Our
    approach then modifies the interior mass distribution such that the principal
    directions of the moment of inertia align with the target rotation frame. To create
    voids inside the model, we represent its volume with an adaptive multiresolution
    voxelization and optimize the discrete voxel fill values using a continuous, nonlinear
    formulation. We further optimize for rotational stability by maximizing the dominant
    principal moment. Our method is well-suited for a variety of 3D printed models,
    ranging from characters to abstract shapes. We demonstrate tops and yo-yos that
    spin surprisingly stably despite their asymmetric appearance.'

  text: We present a computational approach for designing CurveUps, curvy shells that
    form from an initially flat state. They consist of small rigid tiles that are
    tightly held together by two pre-stretched elastic sheets attached to them. Our
    method allows the realization of smooth, doubly curved surfaces that can be fabricated
    as a flat piece. Once released, the restoring forces of the pre-stretched sheets
    support the object to take shape in 3D. CurveUps are structurally stable in their
    target configuration. The design process starts with a target surface. Our method
    generates a tile layout in 2D and optimizes the distribution, shape, and attachment
    areas of the tiles to obtain a configuration that is fabricable and in which the
    curved up state closely matches the target. Our approach is based on an efficient
    approximate model and a local optimization strategy for an otherwise intractable
    nonlinear optimization problem. We demonstrate the effectiveness of our approach
    for a wide range of shapes, all realized as physical prototypes.

  text: Color texture reproduction in 3D printing commonly ignores volumetric light
    transport (cross-talk) between surface points on a 3D print. Such light diffusion
    leads to significant blur of details and color bleeding, and is particularly severe
    for highly translucent resin-based print materials. Given their widely varying
    scattering properties, this cross-talk between surface points strongly depends
    on the internal structure of the volume surrounding each surface point. Existing
    scattering-aware methods use simplified models for light diffusion, and often
    accept the visual blur as an immutable property of the print medium. In contrast,
    our work counteracts heterogeneous scattering to obtain the impression of a crisp
    albedo texture on top of the 3D print, by optimizing for a fully volumetric material
    distribution that preserves the target appearance. Our method employs an efficient
    numerical optimizer on top of a general Monte-Carlo simulation of heterogeneous
    scattering, supported by a practical calibration procedure to obtain scattering
    parameters from a given set of printer materials. Despite the inherent translucency
    of the medium, we reproduce detailed surface textures on 3D prints. We evaluate
    our system using a commercial, five-tone 3D print process and compare against
    the printer’s native color texturing mode, demonstrating that our method preserves
    high-frequency features well without having to compromise on color gamut.

  text: "  We present an interactive design system to create functional mechanical
    \ objects. Our computational approach allows novice users to retarget an  existing
    mechanical template to a user-specified input shape. Our proposed  representation
    for a mechanical template encodes a parameterized mechanism,  mechanical constraints
    that ensure a physically valid configuration, spatial relationships of mechanical
    parts to the user-provided shape, and functional constraints that specify an intended
    functionality. We provide an intuitive interface and optimization-in-the-loop
    approach for finding a valid  configuration of the mechanism and the shape to
    ensure that higher-level  functional goals are met. Our algorithm interactively
    optimizes the mechanism  while the user manipulates the placement of mechanical
    components and the shape. Our system allows users to efficiently explore various
    design choices and to synthesize customized mechanical objects that can be fabricated
    with rapid prototyping technologies. We demonstrate the efficacy of our approach
    by retargeting various mechanical templates to different shapes and fabricating
    the resulting functional mechanical objects.\r\n"

  text: We present a computational method for designing wire sculptures consisting
    of interlocking wires. Our method allows the computation of aesthetically pleasing
    structures that are structurally stable, efficiently fabricatable with a 2D wire
    bending machine, and assemblable without the need of additional connectors. Starting
    from a set of planar contours provided by the user, our method automatically tests
    for the feasibility of a design, determines a discrete ordering of wires at intersection
    points, and optimizes for the rest shape of the individual wires to maximize structural
    stability under frictional contact. In addition to their application to art, wire
    sculptures present an extremely efficient and fast alternative for low-fidelity
    rapid prototyping because manufacturing time and required material linearly scales
    with the physical size of objects. We demonstrate the effectiveness of our approach
    on a varied set of examples, all of which we fabricated.

  text: In this paper, we present a method to model hyperelasticity that is well suited
    for representing the nonlinearity of real-world objects, as well as for estimating
    it from deformation examples. Previous approaches suffer several limitations,
    such as lack of integrability of elastic forces, failure to enforce energy convexity,
    lack of robustness of parameter estimation, or difficulty to model cross-modal
    effects. Our method avoids these problems by relying on a general energy-based
    definition of elastic properties. The accuracy of the resulting elastic model
    is maximized by defining an additive model of separable energy terms, which allow
    progressive parameter estimation. In addition, our method supports efficient modeling
    of extreme nonlinearities thanks to energy-limiting constraints. We combine our
    energy-based model with an optimization method to estimate model parameters from
    force-deformation examples, and we show successful modeling of diverse deformable
    objects, including cloth, human finger skin, and internal human anatomy in a medical
    imaging application.

  text: The accuracy of interdisciplinarity measurements is directly related to the
    quality of the underlying bibliographic data. Existing indicators of interdisciplinarity
    are not capable of reflecting the inaccuracies introduced by incorrect and incomplete
    records because correct and complete bibliographic data can rarely be obtained.
    This is the case for the Rao–Stirling index, which cannot handle references that
    are not categorized into disciplinary fields. We introduce a method that addresses
    this problem. It extends the Rao–Stirling index to acknowledge missing data by
    calculating its interval of uncertainty using computational optimization. The
    evaluation of our method indicates that the uncertainty interval is not only useful
    for estimating the inaccuracy of interdisciplinarity measurements, but it also
    delivers slightly more accurate aggregated interdisciplinarity measurements than
    the Rao–Stirling index.

    natural user interactions at runtime. Designing such objects is a challenging
    and hard problem if attempted manually for all but the simplest geometries and
    deformations. Our method simultaneously optimizes the internal routing of the
    sensing elements and computes a mapping from low-level sensor readings to user-specified
    outputs in order to minimize reconstruction error. We demonstrate the power and
    flexibility of the approach by designing and fabricating a set of flexible input
    devices. Our results indicate that the optimization-based design greatly outperforms
    manual routings in terms of reconstruction accuracy and thus interaction fidelity.

  text: We present an interactive system for computational design, optimization, and
    fabrication of multicopters. Our computational approach allows non-experts to
    design, explore, and evaluate a wide range of different multicopters. We provide
    users with an intuitive interface for assembling a multicopter from a collection
    of components (e.g., propellers, motors, and carbon fiber rods). Our algorithm
    interactively optimizes shape and controller parameters of the current design
    to ensure its proper operation. In addition, we allow incorporating a variety
    of other metrics (such as payload, battery usage, size, and cost) into the design
    process and exploring tradeoffs between them. We show the efficacy of our method
    and system by designing, optimizing, fabricating, and operating multicopters with
    complex geometries and propeller configurations. We also demonstrate the ability
    of our optimization algorithm to improve the multicopter performance under different
    metrics.

  text: We present FlexMolds, a novel computational approach to automatically design
    flexible, reusable molds that, once 3D printed, allow us to physically fabricate,
    by means of liquid casting, multiple copies of complex shapes with rich surface
    details and complex topology. The approach to design such flexible molds is based
    on a greedy bottom-up search of possible cuts over an object, evaluating for each
    possible cut the feasibility of the resulting mold. We use a dynamic simulation
    approach to evaluate candidate molds, providing a heuristic to generate forces
    that are able to open, detach, and remove a complex mold from the object it surrounds.
    We have tested the approach with a number of objects with nontrivial shapes and
    topologies.

  text: Creating mechanical automata that can walk in stable and pleasing manners
    is a challenging task that requires both skill and expertise. We propose to use
    computational design to offset the technical difficulties of this process. A simple
    drag-and-drop interface allows casual users to create personalized walking toys
    from a library of pre-defined template mechanisms. Provided with this input, our
    method leverages physical simulation and evolutionary optimization to refine the
    mechanical designs such that the resulting toys are able to walk. The optimization
    process is guided by an intuitive set of objectives that measure the quality of
    the walking motions. We demonstrate our approach on a set of simulated mechanical
    toys with different numbers of legs and various distinct gaits. Two fabricated
    prototypes showcase the feasibility of our designs.

  text: In recent years we have seen numerous improvements on 3D scanning and tracking
    of human faces, greatly advancing the creation of digital doubles for film and
    video games. However, despite the high-resolution quality of the reconstruction
    approaches available, current methods are unable to capture one of the most important
    regions of the face - the eye region. In this work we present the first method
    for detailed spatio-temporal reconstruction of eyelids. Tracking and reconstructing
    eyelids is extremely challenging, as this region exhibits very complex and unique
    skin deformation where skin is folded under while opening the eye. Furthermore,
    eyelids are often only partially visible and obstructed due to selfocclusion and
    eyelashes. Our approach is to combine a geometric deformation model with image
    data, leveraging multi-view stereo, optical flow, contour tracking and wrinkle
    detection from local skin appearance. Our deformation model serves as a prior
    that enables reconstruction of eyelids even under strong self-occlusions caused
    by rolling and folding skin as the eye opens and closes. The output is a person-specific,
    time-varying eyelid reconstruction with anatomically plausible deformations. Our
    high-resolution detailed eyelids couple naturally with current facial performance
    capture approaches. As a result, our method can largely increase the fidelity
    of facial capture and the creation of digital doubles.

  text: This paper introduces &quot;OmniAD,&quot; a novel data-driven pipeline to
    model and acquire the aerodynamics of three-dimensional rigid objects. Traditionally,
    aerodynamics are examined through elaborate wind tunnel experiments or expensive
    fluid dynamics computations, and are only measured for a small number of discrete
    wind directions. OmniAD allows the evaluation of aerodynamic forces, such as drag
    and lift, for any incoming wind direction using a novel representation based on
    spherical harmonics. Our datadriven technique acquires the aerodynamic properties
    of an object simply by capturing its falling motion using a single camera. Once
    model parameters are estimated, OmniAD enables realistic realtime simulation of
    rigid bodies, such as the tumbling and gliding of leaves, without simulating the
    surrounding air. In addition, we propose an intuitive user interface based on
    OmniAD to interactively design three-dimensional kites that actually fly. Various
    nontraditional kites were designed to demonstrate the physical validity of our
    model.

  text: We present a computational tool for fabrication-oriented design of flexible
    rod meshes. Given a deformable surface and a set of deformed poses as input, our
    method automatically computes a printable rod mesh that, once manufactured, closely
    matches the input poses under the same boundary conditions. The core of our method
    is formed by an optimization scheme that adjusts the cross-sectional profiles
    of the rods and their rest centerline in order to best approximate the target
    deformations. This approach allows us to locally control the bending and stretching
    resistance of the surface with a single material, yielding high design flexibility
    and low fabrication cost.

  text: We propose a method for fabricating deformable objects with spatially varying
    elasticity using 3D printing. Using a single, relatively stiff printer material,
    our method designs an assembly of smallscale microstructures that have the effect
    of a softer material at the object scale, with properties depending on the microstructure
    used in each part of the object. We build on work in the area of metamaterials,
    using numerical optimization to design tiled microstructures with desired properties,
    but with the key difference that our method designs families of related structures
    that can be interpolated to smoothly vary the material properties over a wide
    range. To create an object with spatially varying elastic properties, we tile
    the object's interior with microstructures drawn from these families, generating
    a different microstructure for each cell using an efficient algorithm to select
    compatible structures for neighboring cells. We show results computed for both
    2D and 3D objects, validating several 2D and 3D printed structures using standard
    material tests as well as demonstrating various example applications.

  text: Facial appearance capture is now firmly established within academic research
    and used extensively across various application domains, perhaps most prominently
    in the entertainment industry through the design of virtual characters in video
    games and films. While significant progress has occurred over the last two decades,
    no single survey currently exists that discusses the similarities, differences,
    and practical considerations of the available appearance capture techniques as
    applied to human faces. A central difficulty of facial appearance capture is the
    way light interacts with skin-which has a complex multi-layered structure-and
    the interactions that occur below the skin surface can, by definition, only be
    observed indirectly. In this report, we distinguish between two broad strategies
    for dealing with this complexity. &quot;Image-based methods&quot; try to exhaustively
    capture the exact face appearance under different lighting and viewing conditions,
    and then render the face through weighted image combinations. &quot;Parametric
    methods&quot; instead fit the captured reflectance data to some parametric appearance
    model used during rendering, allowing for a more lightweight and flexible representation
    but at the cost of potentially increased rendering complexity or inexact reproduction.
    The goal of this report is to provide an overview that can guide practitioners
    and researchers in assessing the tradeoffs between current approaches and identifying
    directions for future advances in facial appearance capture.
