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."}],"intvolume":"         2","citation":{"short":"F. Laccone, L. Malomo, J. Perez Rodriguez, N. Pietroni, F.

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"}],"month":"07","type":"journal_article","oa_version":"Submitted Version","volume":38,"file_date_updated":"2020-07-14T12:47:36Z","date_created":"2019-07-22T07:22:28Z","year":"2019","_id":"6660","publication_status":"published","oa":1,"has_accepted_license":"1","date_published":"2019-07-04T00:00:00Z","ddc":["000"],"external_id":{"isi":["000475740600085"]},"status":"public","intvolume":"        38","citation":{"ama":"Sumin D, Weyrich T, Rittig T, et al.

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.

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.","lang":"eng"}],"date_updated":"2023-09-08T11:21:54Z","day":"10","type":"conference","oa_version":"None","month":"10","title":"FlexMaps Pavilion: A twisted arc made of mesostructured flat flexible panels","date_created":"2021-03-21T23:01:21Z","external_id":{"isi":["000563497600059"]},"status":"public","isi":1,"conference":{"end_date":"2019-10-10","location":"Barcelona, Spain","name":"IASS: International Association for Shell and Spatial Structures","start_date":"2019-10-07"},"language":[{"iso":"eng"}],"citation":{"ieee":"F.

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.","lang":"eng"}],"date_updated":"2023-09-19T14:25:30Z","volume":37,"file_date_updated":"2020-07-14T12:47:14Z","date_created":"2019-02-13T13:12:53Z","project":[{"grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425"},{"name":"Soft-bodied intelligence for Manipulation","call_identifier":"H2020","_id":"25082902-B435-11E9-9278-68D0E5697425","grant_number":"645599"},{"grant_number":"754411","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships"}],"isi":1,"issue":"6","language":[{"iso":"eng"}],"publication_identifier":{"issn":["0730-0301"]},"pubrep_id":"1068","doi":"10.1145/3272127.3275076","quality_controlled":"1","publisher":"Association for Computing Machinery (ACM)","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","department":[{"_id":"BeBi"}],"publication":"ACM Transactions on Graphics","article_type":"original","scopus_import":"1","article_processing_charge":"No","ec_funded":1,"author":[{"full_name":"Malomo, Luigi","last_name":"Malomo","first_name":"Luigi"},{"id":"2DC83906-F248-11E8-B48F-1D18A9856A87","full_name":"Perez Rodriguez, Jesus","first_name":"Jesus","last_name":"Perez Rodriguez"},{"last_name":"Iarussi","first_name":"Emmanuel","full_name":"Iarussi, Emmanuel","id":"33F19F16-F248-11E8-B48F-1D18A9856A87"},{"first_name":"Nico","last_name":"Pietroni","full_name":"Pietroni, Nico"},{"first_name":"Eder","last_name":"Miguel","full_name":"Miguel, Eder"},{"first_name":"Paolo","last_name":"Cignoni","full_name":"Cignoni, Paolo"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd","last_name":"Bickel","first_name":"Bernd"}],"file":[{"file_size":100109811,"content_type":"application/pdf","relation":"main_file","creator":"bbickel","file_name":"flexmaps_author_version.pdf","date_created":"2019-09-23T12:48:52Z","access_level":"open_access","file_id":"6901","date_updated":"2020-07-14T12:47:14Z","checksum":"d0529a41c78b37ab8840685579fb33b4"}],"day":"01","article_number":"241","title":"FlexMaps: Computational design of flat flexible shells for shaping 3D objects"},{"date_published":"2018-09-01T00:00:00Z","ddc":["004"],"has_accepted_license":"1","publication_status":"published","oa":1,"citation":{"ama":"Bickel B, Cignoni P, Malomo L, Pietroni N.

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.","lang":"eng"}],"day":"10","date_updated":"2023-09-19T14:49:03Z","month":"09","oa_version":"None","type":"conference","_id":"6195","article_processing_charge":"No","scopus_import":"1","publisher":"IEEE","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","year":"2018","department":[{"_id":"BeBi"}]},{"author":[{"first_name":"Kazutaka","last_name":"Nakashima","full_name":"Nakashima, Kazutaka"},{"full_name":"Auzinger, Thomas","orcid":"0000-0002-1546-3265","id":"4718F954-F248-11E8-B48F-1D18A9856A87","last_name":"Auzinger","first_name":"Thomas"},{"last_name":"Iarussi","first_name":"Emmanuel","full_name":"Iarussi, Emmanuel","id":"33F19F16-F248-11E8-B48F-1D18A9856A87"},{"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"},{"full_name":"Bickel, Bernd","orcid":"0000-0001-6511-9385","id":"49876194-F248-11E8-B48F-1D18A9856A87","last_name":"Bickel","first_name":"Bernd"}],"file":[{"file_name":"IST-2018-1037-v1+1_CoreCavity-AuthorVersion.pdf","creator":"system","file_size":104225664,"relation":"main_file","content_type":"application/pdf","checksum":"6a5368bc86c4e1a9fcfe588fd1f14ee8","file_id":"5360","date_updated":"2020-07-14T12:44:38Z","access_level":"open_access","date_created":"2018-12-12T10:18:38Z"},{"file_name":"IST-2018-1037-v1+2_CoreCavity-Supplemental.zip","relation":"main_file","content_type":"application/zip","file_size":377743553,"creator":"system","date_updated":"2020-07-14T12:44:38Z","file_id":"5361","checksum":"3861e693ba47c51f3ec7b7867d573a61","date_created":"2018-12-12T10:18:39Z","access_level":"open_access"},{"file_name":"IST-2018-1037-v1+3_CoreCavity-Video.mp4","creator":"system","content_type":"video/vnd.objectvideo","relation":"main_file","file_size":162634396,"checksum":"490040c685ed869536e2a18f5a906b94","date_updated":"2020-07-14T12:44:38Z","file_id":"5362","access_level":"open_access","date_created":"2018-12-12T10:18:41Z"},{"creator":"system","file_size":527972,"relation":"main_file","content_type":"image/jpeg","file_name":"IST-2018-1037-v1+4_CoreCavity-RepresentativeImage.jpg","access_level":"open_access","date_created":"2018-12-12T10:18:42Z","checksum":"be7fc8b229adda727419b6504b3b9352","file_id":"5363","date_updated":"2020-07-14T12:44:38Z"}],"day":"04","title":"CoreCavity: Interactive shell decomposition for fabrication with two-piece rigid molds","article_number":"135","publist_id":"8044","publisher":"ACM","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","department":[{"_id":"BeBi"}],"publication":"ACM Transaction on Graphics","article_processing_charge":"No","ec_funded":1,"scopus_import":"1","pubrep_id":"1037","doi":"10.1145/3197517.3201341","quality_controlled":"1","project":[{"name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","_id":"24F9549A-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","grant_number":"715767"},{"grant_number":"642841","call_identifier":"H2020","_id":"2508E324-B435-11E9-9278-68D0E5697425","name":"Distributed 3D Object Design"}],"isi":1,"language":[{"iso":"eng"}],"issue":"4","date_updated":"2023-09-11T12:48:09Z","abstract":[{"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.","lang":"eng"}],"oa_version":"Submitted Version","type":"journal_article","month":"08","volume":37,"file_date_updated":"2020-07-14T12:44:38Z","date_created":"2018-12-11T11:44:09Z","year":"2018","_id":"12","publication_status":"published","oa":1,"has_accepted_license":"1","date_published":"2018-08-04T00:00:00Z","ddc":["004","516","670"],"status":"public","external_id":{"isi":["000448185000096"]},"intvolume":"        37","related_material":{"link":[{"url":"https://ist.ac.at/en/news/interactive-software-tool-makes-complex-mold-design-simple/","description":"News on IST Homepage","relation":"press_release"}]},"citation":{"chicago":"Nakashima, Kazutaka, Thomas Auzinger, Emmanuel Iarussi, Ran Zhang, Takeo Igarashi, and Bernd Bickel. “CoreCavity: Interactive Shell Decomposition for Fabrication with Two-Piece Rigid Molds.” <i>ACM Transaction on Graphics</i>.

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.

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"}],"date_updated":"2023-09-11T14:12:33Z"},{"article_number":"89","title":"Learning three-dimensional flow for interactive aerodynamic design","publist_id":"8053","author":[{"full_name":"Umetani, Nobuyuki","last_name":"Umetani","first_name":"Nobuyuki"},{"last_name":"Bickel","first_name":"Bernd","full_name":"Bickel, Bernd","id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385"}],"file":[{"file_name":"IST-2018-1049-v1+1_2018_sigg_Learning3DAerodynamics.pdf","content_type":"application/pdf","relation":"main_file","file_size":22803163,"creator":"system","date_updated":"2020-07-14T12:46:22Z","file_id":"5216","checksum":"7a2243668f215821bc6aecad0320079a","date_created":"2018-12-12T10:16:28Z","access_level":"open_access"}],"day":"04","publication":"ACM Trans.

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.

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."}],"date_updated":"2023-09-07T13:11:15Z","_id":"486","year":"2017","date_published":"2017-11-20T00:00:00Z","ddc":["003","000","005"],"oa":1,"publication_status":"published","has_accepted_license":"1","intvolume":"        36","related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"8386"}]},"citation":{"ista":"Elek O, Sumin D, Zhang R, Weyrich T, Myszkowski K, Bickel B, Wilkie A, Krivanek J. 2017.

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."}],"oa_version":"Submitted Version","type":"conference","month":"01","_id":"1001","year":"2017"},{"publication_identifier":{"issn":["07300301"]},"pubrep_id":"1050","doi":"10.1145/3072959.3073710","quality_controlled":"1","project":[{"grant_number":"642841","name":"Distributed 3D Object Design","_id":"2508E324-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","_id":"24F9549A-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"conference":{"start_date":"2017-07-30","location":"Los Angeles, CA, United States ","name":"SIGGRAPH: Computer Graphics and Interactive Techniques","end_date":"2017-08-03"},"isi":1,"issue":"4","language":[{"iso":"eng"}],"author":[{"last_name":"Zhang","first_name":"Ran","full_name":"Zhang, Ran","orcid":"0000-0002-3808-281X","id":"4DDBCEB0-F248-11E8-B48F-1D18A9856A87"},{"orcid":"0000-0002-1546-3265","id":"4718F954-F248-11E8-B48F-1D18A9856A87","full_name":"Auzinger, Thomas","last_name":"Auzinger","first_name":"Thomas"},{"full_name":"Ceylan, Duygu","first_name":"Duygu","last_name":"Ceylan"},{"first_name":"Wilmot","last_name":"Li","full_name":"Li, Wilmot"},{"first_name":"Bernd","last_name":"Bickel","full_name":"Bickel, Bernd","id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385"}],"file":[{"relation":"main_file","content_type":"application/pdf","file_size":25463895,"creator":"system","file_name":"IST-2018-1050-v1+1_MechRet.pdf","date_created":"2018-12-12T10:09:05Z","access_level":"open_access","date_updated":"2018-12-12T10:09:05Z","file_id":"4728"}],"day":"01","article_number":"81","title":"Functionality-aware retargeting of mechanisms to 3D shapes","publist_id":"6396","publisher":"ACM","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","department":[{"_id":"BeBi"}],"ec_funded":1,"scopus_import":"1","article_processing_charge":"No","oa":1,"publication_status":"published","has_accepted_license":"1","date_published":"2017-06-01T00:00:00Z","ddc":["003","004"],"alternative_title":["ACM Transactions on Graphics"],"external_id":{"isi":["000406432100049"]},"status":"public","related_material":{"record":[{"status":"public","id":"8386","relation":"dissertation_contains"}]},"intvolume":"        36","citation":{"ama":"Zhang R, Auzinger T, Ceylan D, Li W, Bickel B.

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."}],"date_updated":"2021-11-16T08:29:11Z","volume":107,"date_created":"2018-12-11T11:52:04Z","file_date_updated":"2020-07-14T12:44:55Z","year":"2016","_id":"1446","oa":1,"publication_status":"published","has_accepted_license":"1","ddc":["000"],"date_published":"2016-04-01T00:00:00Z","status":"public","intvolume":"       107","related_material":{"link":[{"relation":"erratum","url":"https://doi.org/10.1007/s11192-016-1902-9"}]},"citation":{"short":"M.
