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.","lang":"eng"}],"project":[{"call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","grant_number":"754411"},{"call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","grant_number":"715767"}],"oa":1,"related_material":{"record":[{"id":"8366","status":"public","relation":"dissertation_contains"},{"id":"7154","status":"public","relation":"research_data"}],"link":[{"description":"News on IST Homepage","relation":"press_release","url":"https://ist.ac.at/en/news/geometry-meets-time/"}]},"ddc":["000"],"_id":"7262","publication":"Nature Communications","title":"Programming temporal morphing of self-actuated shells","date_published":"2020-01-13T00:00:00Z","file":[{"relation":"main_file","date_created":"2020-01-15T14:35:34Z","creator":"rguseino","content_type":"application/pdf","file_size":1315270,"date_updated":"2020-07-14T12:47:55Z","file_id":"7336","file_name":"2020_NatureComm_Guseinov.pdf","checksum":"7db23fef2f4cda712f17f1004116ddff","access_level":"open_access"}],"keyword":["Design","Synthesis and processing","Mechanical engineering","Polymers"],"external_id":{"isi":["000511916800015"]},"publication_identifier":{"issn":["2041-1723"]},"scopus_import":"1","day":"13","date_updated":"2024-02-21T12:45:02Z","type":"journal_article","oa_version":"Published Version","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","article_processing_charge":"No","doi":"10.1038/s41467-019-14015-2","language":[{"iso":"eng"}],"department":[{"_id":"BeBi"}],"has_accepted_license":"1","ec_funded":1},{"page":"509-515","date_published":"2019-10-10T00:00:00Z","external_id":{"isi":["000563497600059"]},"publisher":"International Center for Numerical Methods in Engineering","publication_identifier":{"issn":["2518-6582"],"isbn":["9788412110104"]},"isi":1,"scopus_import":"1","status":"public","date_created":"2021-03-21T23:01:21Z","conference":{"end_date":"2019-10-10","name":"IASS: International Association for Shell and Spatial Structures","start_date":"2019-10-07","location":"Barcelona, Spain"},"month":"10","article_processing_charge":"No","quality_controlled":"1","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","author":[{"full_name":"Laccone, Francesco","last_name":"Laccone","first_name":"Francesco"},{"full_name":"Malomo, Luigi","last_name":"Malomo","first_name":"Luigi"},{"full_name":"Perez Rodriguez, Jesus","id":"2DC83906-F248-11E8-B48F-1D18A9856A87","last_name":"Perez Rodriguez","first_name":"Jesus"},{"full_name":"Pietroni, Nico","last_name":"Pietroni","first_name":"Nico"},{"full_name":"Ponchio, Federico","last_name":"Ponchio","first_name":"Federico"},{"first_name":"Bernd","last_name":"Bickel","id":"49876194-F248-11E8-B48F-1D18A9856A87","full_name":"Bickel, Bernd","orcid":"0000-0001-6511-9385"},{"full_name":"Cignoni, Paolo","first_name":"Paolo","last_name":"Cignoni"}],"citation":{"ieee":"F.

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."}]},{"quality_controlled":"1","author":[{"id":"400429CC-F248-11E8-B48F-1D18A9856A87","full_name":"Hafner, Christian","first_name":"Christian","last_name":"Hafner"},{"full_name":"Schumacher, Christian","first_name":"Christian","last_name":"Schumacher"},{"full_name":"Knoop, Espen","first_name":"Espen","last_name":"Knoop"},{"id":"4718F954-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1546-3265","full_name":"Auzinger, Thomas","last_name":"Auzinger","first_name":"Thomas"},{"full_name":"Bickel, Bernd","orcid":"0000-0001-6511-9385","id":"49876194-F248-11E8-B48F-1D18A9856A87","first_name":"Bernd","last_name":"Bickel"},{"first_name":"Moritz","last_name":"Bächer","full_name":"Bächer, Moritz"}],"citation":{"ama":"Hafner C, Schumacher C, Knoop E, Auzinger T, Bickel B, Bächer M.

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."}],"project":[{"name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","grant_number":"715767","_id":"24F9549A-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"volume":38,"issue":"6","publisher":"ACM","article_type":"original","file_date_updated":"2020-07-14T12:47:49Z","isi":1,"intvolume":"        38","status":"public","article_number":"157","date_created":"2019-11-26T14:22:09Z","month":"11","article_processing_charge":"No","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","day":"06","date_updated":"2024-03-25T23:30:26Z","type":"journal_article","oa_version":"Submitted Version","doi":"10.1145/3355089.3356576","language":[{"iso":"eng"}],"department":[{"_id":"BeBi"}],"has_accepted_license":"1","ec_funded":1,"date_published":"2019-11-06T00:00:00Z","external_id":{"isi":["000498397300007"]},"file":[{"checksum":"56a2fb019adcb556d2b022f5e5acb68c","file_name":"xcad_sup_mat_siga19.pdf","access_level":"open_access","date_updated":"2020-07-14T12:47:49Z","file_id":"7119","content_type":"application/pdf","creator":"bbickel","file_size":1673176,"title":"X-CAD Supplemental Material","relation":"supplementary_material","date_created":"2019-11-26T14:24:26Z"},{"relation":"main_file","date_created":"2019-11-26T14:24:27Z","creator":"bbickel","content_type":"application/pdf","file_size":14563618,"title":"X-CAD: Optimizing CAD Models with Extended Finite Elements","date_updated":"2020-07-14T12:47:49Z","file_id":"7120","file_name":"XCAD_authors_version.pdf","checksum":"5f29d76aceb5102e766cbab9b17d776e","access_level":"open_access","description":"This is the author's version of the work."},{"access_level":"open_access","checksum":"0d31e123286cbec9e28b2001c2bb0d55","file_name":"XCAD_video.mp4","file_id":"7121","date_updated":"2020-07-14T12:47:49Z","content_type":"video/mp4","creator":"bbickel","file_size":259979129,"date_created":"2019-11-26T14:27:37Z","relation":"main_file"}],"publication_identifier":{"issn":["0730-0301"]},"scopus_import":"1"},{"article_processing_charge":"No","author":[{"last_name":"Guseinov","first_name":"Ruslan","id":"3AB45EE2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9819-5077","full_name":"Guseinov, Ruslan"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"apa":"Guseinov, R.

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.","lang":"eng"}],"title":"Geometry-aware scattering compensation for 3D printing","publication":"ACM Transactions on Graphics","ddc":["000"],"oa":1,"_id":"6660","year":"2019","citation":{"apa":"Sumin, D., Weyrich, T., Rittig, T., Babaei, V., Nindel, T., Wilkie, A., … Myszkowski, K.

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.","lang":"eng"}],"project":[{"call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","grant_number":"715767"}],"quality_controlled":"1","author":[{"full_name":"Bickel, Bernd","orcid":"0000-0001-6511-9385","id":"49876194-F248-11E8-B48F-1D18A9856A87","first_name":"Bernd","last_name":"Bickel"},{"last_name":"Cignoni","first_name":"Paolo","full_name":"Cignoni, Paolo"},{"full_name":"Malomo, Luigi","last_name":"Malomo","first_name":"Luigi"},{"full_name":"Pietroni, Nico","last_name":"Pietroni","first_name":"Nico"}],"citation":{"ieee":"B.

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."}],"publication_status":"published","citation":{"short":"M. Pozzi, E. Miguel Villalba, R. Deimel, M. Malvezzi, B. Bickel, O.

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."}],"project":[{"grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425"},{"grant_number":"642841","name":"Distributed 3D Object Design","_id":"2508E324-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"quality_controlled":"1","author":[{"first_name":"Kazutaka","last_name":"Nakashima","full_name":"Nakashima, Kazutaka"},{"orcid":"0000-0002-1546-3265","full_name":"Auzinger, Thomas","id":"4718F954-F248-11E8-B48F-1D18A9856A87","first_name":"Thomas","last_name":"Auzinger"},{"full_name":"Iarussi, Emmanuel","id":"33F19F16-F248-11E8-B48F-1D18A9856A87","last_name":"Iarussi","first_name":"Emmanuel"},{"id":"4DDBCEB0-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3808-281X","full_name":"Zhang, Ran","first_name":"Ran","last_name":"Zhang"},{"full_name":"Igarashi, Takeo","last_name":"Igarashi","first_name":"Takeo"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd","first_name":"Bernd","last_name":"Bickel"}],"citation":{"ieee":"K.

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.","lang":"eng"}],"publication_status":"published"},{"year":"2018","author":[{"full_name":"Umetani, Nobuyuki","first_name":"Nobuyuki","last_name":"Umetani"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd","last_name":"Bickel","first_name":"Bernd"}],"quality_controlled":"1","citation":{"mla":"Umetani, Nobuyuki, and Bernd Bickel. “Learning Three-Dimensional Flow for Interactive Aerodynamic Design.” <i>ACM Trans.

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.

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.","lang":"eng"}],"publication_status":"published","project":[{"call_identifier":"H2020","_id":"25082902-B435-11E9-9278-68D0E5697425","grant_number":"645599","name":"Soft-bodied intelligence for Manipulation"},{"call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","grant_number":"715767"}],"_id":"1001","ddc":["003","004"],"oa":1,"related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"8366"}]},"title":"CurveUps: Shaping objects from flat plates with tension-actuated curvature","external_id":{"isi":["000406432100032"]},"file":[{"file_size":36159696,"content_type":"application/pdf","creator":"system","relation":"main_file","date_created":"2018-12-12T10:10:24Z","file_name":"IST-2018-1053-v1+1_CurveUp.pdf","access_level":"open_access","file_id":"4811","date_updated":"2018-12-12T10:10:24Z"}],"date_published":"2017-01-01T00:00:00Z","alternative_title":["ACM Transactions on Graphics"],"day":"01","oa_version":"Submitted Version","date_updated":"2023-09-22T09:49:58Z","type":"conference","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","article_processing_charge":"No","department":[{"_id":"BeBi"}],"has_accepted_license":"1","doi":"10.1145/3072959.3073709","language":[{"iso":"eng"}],"ec_funded":1},{"ec_funded":1,"language":[{"iso":"eng"}],"doi":"10.1145/3072959.3073710","has_accepted_license":"1","department":[{"_id":"BeBi"}],"type":"conference","date_updated":"2023-09-22T09:49:31Z","oa_version":"Submitted Version","day":"01","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","article_processing_charge":"No","alternative_title":["ACM Transactions on Graphics"],"publication_identifier":{"issn":["07300301"]},"scopus_import":"1","date_published":"2017-06-01T00:00:00Z","external_id":{"isi":["000406432100049"]},"file":[{"relation":"main_file","date_created":"2018-12-12T10:09:05Z","creator":"system","content_type":"application/pdf","file_size":25463895,"file_id":"4728","date_updated":"2018-12-12T10:09:05Z","file_name":"IST-2018-1050-v1+1_MechRet.pdf","access_level":"open_access"}],"project":[{"call_identifier":"H2020","_id":"2508E324-B435-11E9-9278-68D0E5697425","name":"Distributed 3D Object Design","grant_number":"642841"},{"grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425"}],"publication_status":"published","abstract":[{"text":"  We present an interactive design system to create functional mechanical  objects.

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."}],"publication":"ACM Transactions on Graphics","title":"Scattering-aware texture reproduction for 3D printing","ddc":["003","000","005"],"related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"8386"}]},"oa":1,"_id":"486","year":"2017","citation":{"chicago":"Elek, Oskar, Denis Sumin, Ran Zhang, Tim Weyrich, Karol Myszkowski, Bernd Bickel, Alexander Wilkie, and Jaroslav Krivanek. “Scattering-Aware Texture Reproduction for 3D Printing.” <i>ACM Transactions on Graphics</i>.

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."}],"project":[{"call_identifier":"H2020","_id":"25082902-B435-11E9-9278-68D0E5697425","grant_number":"645599","name":"Soft-bodied intelligence for Manipulation"}],"ddc":["006"],"oa":1,"_id":"1364","title":"Computational design of stable planar-rod structures","publisher":"ACM","file_date_updated":"2020-07-14T12:44:47Z","issue":"4","volume":35,"pubrep_id":"763","article_number":"86","status":"public","date_created":"2018-12-11T11:51:36Z","month":"07","conference":{"end_date":"2016-07-28","name":"ACM SIGGRAPH","location":"Anaheim, CA, USA","start_date":"2016-07-24"},"publist_id":"5878","intvolume":"        35","day":"01","type":"conference","date_updated":"2021-01-12T06:50:10Z","oa_version":"Preprint","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","acknowledgement":"This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 645599.","language":[{"iso":"eng"}],"doi":"10.1145/2897824.2925978","has_accepted_license":"1","department":[{"_id":"BeBi"}],"ec_funded":1,"date_published":"2016-07-01T00:00:00Z","file":[{"date_created":"2018-12-12T10:11:01Z","relation":"main_file","file_size":44766392,"content_type":"application/pdf","creator":"system","file_id":"4853","date_updated":"2020-07-14T12:44:47Z","access_level":"open_access","checksum":"d00c2664a43d945df8876ea0193734e3","file_name":"IST-2017-763-v1+1_wirebending.pdf"}],"scopus_import":1,"alternative_title":["ACM Transactions on Graphics"]},{"date_published":"2016-05-01T00:00:00Z","page":"385 - 396","issue":"2","volume":35,"publisher":"Wiley-Blackwell","intvolume":"        35","publist_id":"5792","scopus_import":1,"date_created":"2018-12-11T11:51:53Z","month":"05","status":"public","citation":{"apa":"Miguel Villalba, E., Miraut, D., &#38; Otaduy, M.

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."}]}]
