  text: "Form versus function is a long-standing debate in various design-related
    fields, such as architecture as well as graphic and industrial design. A good
    design that balances form and function often requires considerable human effort
    and collaboration among experts from different professional fields. Computational
    design tools provide a new paradigm for designing functional objects. In computational
    design, form and function are represented as mathematical\r\nquantities, with
    the help of numerical and combinatorial algorithms, they can assist even novice
    users in designing versatile models that exhibit their desired functionality.
    This thesis presents three disparate research studies on the computational design
    of functional objects: The appearance of 3d print—we optimize the volumetric material
    distribution for faithfully replicating colored surface texture in 3d printing;
    the dynamic motion of mechanical structures—\r\nour design system helps the novice
    user to retarget various mechanical templates with different functionality to
    complex 3d shapes; and a more abstract functionality, multistability—our algorithm
    automatically generates models that exhibit multiple stable target poses. For
    each of these cases, our computational design tools not only ensure the functionality
    of the results but also permit the user aesthetic freedom over the form. Moreover,
    fabrication constraints\r\nwere taken into account, which allow for the immediate
    creation of physical realization via 3D printing or laser cutting."

  text: "Cold bent glass is a promising and cost-efficient method for realizing doubly
    curved glass facades. They are produced by attaching planar glass sheets to curved
    frames and require keeping the occurring stress within safe limits.\r\nHowever,
    it is very challenging to navigate the design space of cold bent glass panels
    due to the fragility of the material, which impedes the form-finding for practically
    feasible and aesthetically pleasing cold bent glass facades. We propose an interactive,
    data-driven approach for designing cold bent glass facades that can be seamlessly
    integrated into a typical architectural design pipeline. Our method allows non-expert
    users to interactively edit a parametric surface while providing real-time feedback
    on the deformed shape and maximum stress of cold bent glass panels. Designs are
    automatically refined to minimize several fairness criteria while maximal stresses
    are kept within glass limits. We achieve interactive frame rates by using a differentiable
    Mixture Density Network trained from more than a million simulations. Given a
    curved boundary, our regression model is capable of handling multistable\r\nconfigurations
    and accurately predicting the equilibrium shape of the panel and its corresponding
    maximal stress. We show predictions are highly accurate and validate our results
    with a physical realization of a cold bent glass surface."

  text: "The “procedural” approach to animating ocean waves is the dominant algorithm
    for animating larger bodies of water in\r\ninteractive applications as well as
    in off-line productions — it provides high visual quality with a low computational
    demand. In this paper, we widen the applicability of procedural water wave animation
    with an extension that guarantees the satisfaction of boundary conditions imposed
    by terrain while still approximating physical wave behavior. In combination with
    a particle system that models wave breaking, foam, and spray, this allows us to
    naturally model waves interacting with beaches and rocks. Our system is able to
    animate waves at large scales at interactive frame rates on a commodity PC."

  text: 'Bending-active structures are able to efficiently produce complex curved
    shapes from flat panels. The desired deformation of the panels derives from the
    proper selection of their elastic properties. Optimized panels, called FlexMaps,
    are designed such that, once they are bent and assembled, the resulting static
    equilibrium configuration matches a desired input 3D shape. The FlexMaps elastic
    properties are controlled by locally varying spiraling geometric mesostructures,
    which are optimized in size and shape to match specific bending requests, namely
    the global curvature of the target shape. The design pipeline starts from a quad
    mesh representing the input 3D shape, which defines the edge size and the total
    amount of spirals: every quad will embed one spiral. Then, an optimization algorithm
    tunes the geometry of the spirals by using a simplified pre-computed rod model.
    This rod model is derived from a non-linear regression algorithm which approximates
    the non-linear behavior of solid FEM spiral models subject to hundreds of load
    combinations. This innovative pipeline has been applied to the project of a lightweight
    plywood pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted
    arch that fits a bounding box of 3.90x3.96x3.25 meters. This case study serves
    to test the applicability of this methodology at the architectural scale. The
    structure is validated via FE analyses and the fabrication of the full scale prototype.'

  text: The combined resection of skull-infiltrating tumours and immediate cranioplastic
    reconstruction predominantly relies on freehand-moulded solutions. Techniques
    that enable this procedure to be performed easily in routine clinical practice
    would be useful. A cadaveric study was developed in which a new software tool
    was used to perform single-stage reconstructions with prefabricated implants after
    the resection of skull-infiltrating pathologies. A novel 3D visualization and
    interaction framework was developed to create 10 virtual craniotomies in five
    cadaveric specimens. Polyether ether ketone (PEEK) implants were manufactured
    according to the bone defects. The image-guided craniotomy was reconstructed with
    PEEK and compared to polymethyl methacrylate (PMMA). Navigational accuracy and
    surgical precision were assessed. The PEEK workflow resulted in up to 10-fold
    shorter reconstruction times than the standard technique. Surgical precision was
    reflected by the mean 1.1 ± 0.29 mm distance between the virtual and real craniotomy,
    with submillimetre precision in 50%. Assessment of the global offset between virtual
    and actual craniotomy revealed an average shift of 4.5 ± 3.6 mm. The results validated
    the ‘elective single-stage cranioplasty’ technique as a state-of-the-art virtual
    planning method and surgical workflow. This patient-tailored workflow could significantly
    reduce surgical times compared to the traditional, intraoperative acrylic moulding
    method and may be an option for the reconstruction of bone defects in the craniofacial
    region.

  text: BACKGROUND:The introduction of image-guided methods to bypass surgery has
    resulted in optimized preoperative identification of the recipients and excellent
    patency rates. However, the recently presented methods have also been resource-consuming.
    In the present study, we have reported a cost-efficient planning workflow for
    extracranial-intracranial (EC-IC) revascularization combined with transdural indocyanine
    green videoangiography (tICG-VA). METHODS:We performed a retrospective review
    at a single tertiary referral center from 2011 to 2018. A novel software-derived
    workflow was applied for 25 of 92 bypass procedures during the study period. The
    precision and accuracy were assessed using tICG-VA identification of the cortical
    recipients and a comparison of the virtual and actual data. The data from a control
    group of 25 traditionally planned procedures were also matched. RESULTS:The intraoperative
    transfer time of the calculated coordinates averaged 0.8 minute (range, 0.4-1.9
    minutes). The definitive recipients matched the targeted branches in 80%, and
    a neighboring branch was used in 16%. Our workflow led to a significant craniotomy
    size reduction in the study group compared with that in the control group (P =
    0.005). tICG-VA was successfully applied in 19 cases. An average of 2 potential
    recipient arteries were identified transdurally, resulting in tailored durotomy
    and 3 craniotomy adjustments. Follow-up patency results were available for 49
    bypass surgeries, comprising 54 grafts. The overall patency rate was 91% at a
    median follow-up period of 26 months. No significant difference was found in the
    patency rate between the study and control groups (P = 0.317). CONCLUSIONS:Our
    clinical results have validated the presented planning and surgical workflow and
    support the routine implementation of tICG-VA for recipient identification before
    durotomy.

  text: Advances in shape-morphing materials, such as hydrogels, shape-memory polymers
    and light-responsive polymers have enabled prescribing self-directed deformations
    of initially flat geometries. However, most proposed solutions evolve towards
    a target geometry without considering time-dependent actuation paths. To achieve
    more complex geometries and avoid self-collisions, it is critical to encode a
    spatial and temporal shape evolution within the initially flat shell. Recent realizations
    of time-dependent morphing are limited to the actuation of few, discrete hinges
    and cannot form doubly curved surfaces. Here, we demonstrate a method for encoding
    temporal shape evolution in architected shells that assume complex shapes and
    doubly curved geometries. The shells are non-periodic tessellations of pre-stressed
    contractile unit cells that soften in water at rates prescribed locally by mesostructure
    geometry. The ensuing midplane contraction is coupled to the formation of encoded
    curvatures. We propose an inverse design tool based on a data-driven model for
    unit cells’ temporal responses.

  text: 'Bending-active structures are able to efficiently produce complex curved
    shapes starting from flat panels. The desired deformation of the panels derives
    from the proper selection of their elastic properties. Optimized panels, called
    FlexMaps, are designed such that, once they are bent and assembled, the resulting
    static equilibrium configuration matches a desired input 3D shape. The FlexMaps
    elastic properties are controlled by locally varying spiraling geometric mesostructures,
    which are optimized in size and shape to match the global curvature (i.e., bending
    requests) of the target shape. The design pipeline starts from a quad mesh representing
    the input 3D shape, which defines the edge size and the total amount of spirals:
    every quad will embed one spiral. Then, an optimization algorithm tunes the geometry
    of the spirals by using a simplified pre-computed rod model. This rod model is
    derived from a non-linear regression algorithm which approximates the non-linear
    behavior of solid FEM spiral models subject to hundreds of load combinations.
    This innovative pipeline has been applied to the project of a lightweight plywood
    pavilion named FlexMaps Pavilion, which is a single-layer piecewise twisted arc
    that fits a bounding box of 3.90x3.96x3.25 meters.'

  text: We propose a novel technique for the automatic design of molds to cast highly
    complex shapes. The technique generates composite, two-piece molds. Each mold
    piece is made up of a hard plastic shell and a flexible silicone part. Thanks
    to the thin, soft, and smartly shaped silicone part, which is kept in place by
    a hard plastic shell, we can cast objects of unprecedented complexity. An innovative
    algorithm based on a volumetric analysis defines the layout of the internal cuts
    in the silicone mold part. Our approach can robustly handle thin protruding features
    and intertwined topologies that have caused previous methods to fail. We compare
    our results with state of the art techniques, and we demonstrate the casting of
    shapes with extremely complex geometry.

  text: "Commercially available full-color 3D printing allows for detailed control
    of material deposition in a volume, but an exact reproduction of a target surface
    appearance is hampered by the strong subsurface scattering that causes nontrivial
    volumetric cross-talk at the print surface. Previous work showed how an iterative
    optimization scheme based on accumulating absorptive materials at the surface
    can be used to find a volumetric distribution of print materials that closely
    approximates a given target appearance.\r\n\r\nIn this work, we first revisit
    the assumption that pushing the absorptive materials to the surface results in
    minimal volumetric cross-talk. We design a full-fledged optimization on a small
    domain for this task and confirm this previously reported heuristic. Then, we
    extend the above approach that is critically limited to color reproduction on
    planar surfaces, to arbitrary 3D shapes. Our method enables high-fidelity color
    texture reproduction on 3D prints by effectively compensating for internal light
    scattering within arbitrarily shaped objects. In addition, we propose a content-aware
    gamut mapping that significantly improves color reproduction for the pathological
    case of thin geometric features. Using a wide range of sample objects with complex
    textures and geometries, we demonstrate color reproduction whose fidelity is superior
    to state-of-the-art drivers for color 3D printers."

  text: We propose a novel generic shape optimization method for CAD models based
    on the eXtended Finite Element Method (XFEM). Our method works directly on the
    intersection between the model and a regular simulation grid, without the need
    to mesh or remesh, thus removing a bottleneck of classical shape optimization
    strategies. This is made possible by a novel hierarchical integration scheme that
    accurately integrates finite element quantities with sub-element precision. For
    optimization, we efficiently compute analytical shape derivatives of the entire
    framework, from model intersection to integration rule generation and XFEM simulation.
    Moreover, we describe a differentiable projection of shape parameters onto a constraint
    manifold spanned by user-specified shape preservation, consistency, and manufacturability
    constraints. We demonstrate the utility of our approach by optimizing mass distribution,
    strength-to-weight ratio, and inverse elastic shape design objectives directly
    on parameterized 3D CAD models.

  text: "Additive manufacturing has recently seen drastic improvements in resolution,
    making it now possible to fabricate features at scales of hundreds or even dozens
    of nanometers, which previously required very expensive lithographic methods.\r\nAs
    a result, additive manufacturing now seems poised for optical applications, including
    those relevant to computer graphics, such as material design, as well as display
    and imaging applications.\r\n \r\nIn this work, we explore the use of additive
    manufacturing for generating structural colors, where the structures are designed
    using a fabrication-aware optimization process.\r\nThis requires a combination
    of full-wave simulation, a feasible parameterization of the design space, and
    a tailored optimization procedure.\r\nMany of these components should be re-usable
    for the design of other optical structures at this scale.\r\n \r\nWe show initial
    results of material samples fabricated based on our designs.\r\nWhile these suffer
    from the prototype character of state-of-the-art fabrication hardware, we believe
    they clearly demonstrate the potential of additive nanofabrication for structural
    colors and other graphics applications."

  text: We propose FlexMaps, a novel framework for fabricating smooth shapes out of
    flat, flexible panels with tailored mechanical properties. We start by mapping
    the 3D surface onto a 2D domain as in traditional UV mapping to design a set of
    deformable flat panels called FlexMaps. For these panels, we design and obtain
    specific mechanical properties such that, once they are assembled, the static
    equilibrium configuration matches the desired 3D shape. FlexMaps can be fabricated
    from an almost rigid material, such as wood or plastic, and are made flexible
    in a controlled way by using computationally designed spiraling microstructures.

  text: Digital fabrication devices are powerful tools for creating tangible reproductions
    of 3D digital models. Most available printing technologies aim at producing an
    accurate copy of a tridimensional shape. However, fabrication technologies can
    also be used to create a stylistic representation of a digital shape. We refer
    to this class of methods as ‘stylized fabrication methods’. These methods abstract
    geometric and physical features of a given shape to create an unconventional representation,
    to produce an optical illusion or to devise a particular interaction with the
    fabricated model. In this state‐of‐the‐art report, we classify and overview this
    broad and emerging class of approaches and also propose possible directions for
    future research.

  text: In the context of robotic manipulation and grasping, the shift from a view
    that is static (force closure of a single posture) and contact-deprived (only
    contact for force closure is allowed, everything else is obstacle) towards a view
    that is dynamic and contact-rich (soft manipulation) has led to an increased interest
    in soft hands. These hands can easily exploit environmental constraints and object
    surfaces without risk, and safely interact with humans, but present also some
    challenges. Designing them is difficult, as well as predicting, modelling, and
    “programming” their interactions with the objects and the environment. This paper
    tackles the problem of simulating them in a fast and effective way, leveraging
    on novel and existing simulation technologies. We present a triple-layered simulation
    framework where dynamic properties such as stiffness are determined from slow
    but accurate FEM simulation data once, and then condensed into a lumped parameter
    model that can be used to fast simulate soft fingers and soft hands. We apply
    our approach to the simulation of soft pneumatic fingers.

  text: 'Objective: To report long-term results after Pipeline Embolization Device
    (PED) implantation, characterize complex and standard aneurysms comprehensively,
    and introduce a modified flow disruption scale. Methods: We retrospectively reviewed
    a consecutive series of 40 patients harboring 59 aneurysms treated with 54 PEDs.
    Aneurysm complexity was assessed using our proposed classification. Immediate
    angiographic results were analyzed using previously published grading scales and
    our novel flow disruption scale. Results: According to our new definition, 46
    (78%) aneurysms were classified as complex. Most PED interventions were performed
    in the paraophthalmic and cavernous internal carotid artery segments. Excellent
    neurologic outcome (modified Rankin Scale 0 and 1) was observed in 94% of patients.
    Our data showed low permanent procedure-related mortality (0%) and morbidity (3%)
    rates. Long-term angiographic follow-up showed complete occlusion in 81% and near-total
    obliteration in a further 14%. Complete obliteration after deployment of a single
    PED was achieved in all standard aneurysms with 1-year follow-up. Our new scale
    was an independent predictor of aneurysm occlusion in a multivariable analysis.
    All aneurysms with a high flow disruption grade showed complete occlusion at follow-up
    regardless of PED number or aneurysm complexity. Conclusions: Treatment with the
    PED should be recognized as a primary management strategy for a highly selected
    cohort with predominantly complex intracranial aneurysms. We further show that
    a priori assessment of aneurysm complexity and our new postinterventional angiographic
    flow disruption scale predict occlusion probability and may help to determine
    the adequate number of per-aneurysm devices.'

  text: Molding is a popular mass production method, in which the initial expenses
    for the mold are offset by the low per-unit production cost. However, the physical
    fabrication constraints of the molding technique commonly restrict the shape of
    moldable objects. For a complex shape, a decomposition of the object into moldable
    parts is a common strategy to address these constraints, with plastic model kits
    being a popular and illustrative example. However, conducting such a decomposition
    requires considerable expertise, and it depends on the technical aspects of the
    fabrication technique, as well as aesthetic considerations. We present an interactive
    technique to create such decompositions for two-piece molding, in which each part
    of the object is cast between two rigid mold pieces. Given the surface description
    of an object, we decompose its thin-shell equivalent into moldable parts by first
    performing a coarse decomposition and then utilizing an active contour model for
    the boundaries between individual parts. Formulated as an optimization problem,
    the movement of the contours is guided by an energy reflecting fabrication constraints
    to ensure the moldability of each part. Simultaneously, the user is provided with
    editing capabilities to enforce aesthetic guidelines. Our interactive interface
    provides control of the contour positions by allowing, for example, the alignment
    of part boundaries with object features. Our technique enables a novel workflow,
    as it empowers novice users to explore the design space, and it generates fabrication-ready
    two-piece molds that can be used either for casting or industrial injection molding
    of free-form objects.

  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.
