In the shape modeling of deformable objects for Computer Graphics or Virtual Reality, if the intuitive physical modification operations as those used in real clay craft, e.g., simple modification operations like pressing, bending and extending, are possible, \"virtual clay craft\" would be realizable. Such a realistic shape modeling technique has many applications in the areas of education, art, amusement, virtual reality, and so on. In this paper, we propose a clay model implemented by employing the particle based numerical simulation method where every pair of particles receives specific virtual mutual forces each other. These virtual forces consist of gravity, attractive force, repulsive force, friction force and external force that realize clay-like deformation of objects. Actual clay has the property of plasticity where its shape remains as it was after the external forces are removed. Our clay model realizes not only the fundamental modification operations applied to clay but also the plasticity.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"62101","nameIdentifierScheme":"WEKO"}],"names":[{"name":"ODA, YASUYUKI"}]},{"nameIdentifiers":[{"nameIdentifier":"62102","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MURAOKA, KAZUNOBU"}]},{"nameIdentifiers":[{"nameIdentifier":"62103","nameIdentifierScheme":"WEKO"}],"names":[{"name":"CHIBA, NORISHIGE"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"情報処理学会"}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"(c) 情報処理学会"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-7764","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学大学院工学研究科"},{"subitem_text_value":"岩手大学工学部情報システム工学科"},{"subitem_text_value":"岩手大学工学部情報システム工学科"}]},"item_16_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小田, 泰行"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"村岡, 一信"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"千葉, 則茂"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"tipsj-v42n5p1142-1150.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tipsj-v42n5p1142-1150.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9993/files/tipsj-v42n5p1142-1150.pdf"},"version_id":"a71153e4-6875-4fa0-91f2-8177e510db23"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"仮想粘土の粒子ベース・ビジュアルシミュレーション","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"仮想粘土の粒子ベース・ビジュアルシミュレーション"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-10-05"},"publish_date":"2010-10-05","publish_status":"0","recid":"9993","relation_version_is_last":true,"title":["仮想粘土の粒子ベース・ビジュアルシミュレーション"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:50:26.528822+00:00"}
