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 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: 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 new method for fabricating digital objects through reusable silicone
molds. Molds are generated by casting liquid silicone into custom 3D printed containers
called metamolds. Metamolds automatically define the cuts that are needed to extract
the cast object from the silicone mold. The shape of metamolds is designed through
a novel segmentation technique, which takes into account both geometric and topological
constraints involved in the process of mold casting. Our technique is simple,
does not require changing the shape or topology of the input objects, and only
requires off-the- shelf materials and technologies. We successfully tested our
method on a set of challenging examples with complex shapes and rich geometric
detail. © 2018 Association for Computing Machinery.

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: 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: "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: '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: 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: 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: " 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: 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 a novel optimization-based algorithm for the design and fabrication
of customized, deformable input devices, capable of continuously sensing their
deformation. We propose to embed piezoresistive sensing elements into flexible
3D printed objects. These sensing elements are then utilized to recover rich and
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 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.
