Example-based elastic deformation was originally presented by Martin et al., where an artist can intuitively control elastic material behaviors by simply giving example deformed poses. Their FEM-based approach is, however, computationally expensive requiring nonlinear optimization, which hinders its use in real-time applications such as games. Our contribution is to formulate an analogous concept using the shape matching framework, which is fast, robust, and easy to implement, without using nonlinear optimization. Our approach is two or three orders of magnitude faster than Martin et al.'s approach while producing comparable example-based elastic deformations.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2324","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2316","bibliographicIssueDates":{"bibliographicIssueDate":"2013-10-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"10","bibliographicVolumeNumber":"54"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-18T23:42:31.491593+00:00","id":95427,"links":{}}
