--- _id: '1002' abstract: - lang: eng 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" alternative_title: - ACM Transactions on Graphics article_number: '81' article_processing_charge: No author: - first_name: Ran full_name: Zhang, Ran id: 4DDBCEB0-F248-11E8-B48F-1D18A9856A87 last_name: Zhang orcid: 0000-0002-3808-281X - first_name: Thomas full_name: Auzinger, Thomas id: 4718F954-F248-11E8-B48F-1D18A9856A87 last_name: Auzinger orcid: 0000-0002-1546-3265 - first_name: Duygu full_name: Ceylan, Duygu last_name: Ceylan - first_name: Wilmot full_name: Li, Wilmot last_name: Li - first_name: Bernd full_name: Bickel, Bernd id: 49876194-F248-11E8-B48F-1D18A9856A87 last_name: Bickel orcid: 0000-0001-6511-9385 citation: ama: 'Zhang R, Auzinger T, Ceylan D, Li W, Bickel B.
