A wrinkly surface is a unification of a interpolation surface and a fractal surface, and it is a parametric surface which is generated on a mesh of control points as a usual interpolation surface is. The interpolation procedure called \"Iterated Shuffle Transformation: IST\" applied to control points gives the property of \"local resemblance in space/scale direction\". This means that the surface has locality in the space direction and self-similarity in the scale direction. By changing the control point positions and their attributes such as height values, colors, or transparency, we can modify the shape locally; this is difficult for usual global fractal methods. We presented a method of generating a wrinkly surface on a regular mesh before. In this paper, we improve two-dimensional Iterated Shuffle Transformation to be applied on an irregular mesh which is constrained by the condition \"two-grouping of global axes\", and propose the method of generating a wrinkly surface on the constrained irregular mesh. After giving several wrinkly surfaces on typical irregular meshes as examples, we show the excellent ability of wrinkly surface for shape modeling through making some shape models actually.","subitem_description_type":"Other"}]},"item_16_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"60770","nameIdentifierScheme":"WEKO"}],"names":[{"name":"FUJIMOTO, TADAHIRO"}]},{"nameIdentifiers":[{"nameIdentifier":"60771","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OHNO, YOSHIO"}]}]},"item_16_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人情報処理学会"}]},"item_16_rights_18":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"©社団法人情報処理学会"},{"subitem_rights":"ここに掲載した著作物の利用に関する注意 本著作物の著作権は（社）情報処理学会に帰属します。本著作物は著作権者である情報処理学会の許可のもとに掲載するものです。ご利用に当たっては「著作権法」ならびに「情報処理学会倫理綱領」に従うことをお願いいたします。"}]},"item_16_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0387-5806","subitem_source_identifier_type":"ISSN"}]},"item_16_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"慶應義塾大学大学院理工学研究科, (現)岩手大学工学部"},{"subitem_text_value":"慶應義塾大学理工学部"}]},"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":"藤本, 忠博"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大野, 義夫"}],"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+v40n10p3672-3684.pdf","filesize":[{"value":"2.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"tipsj+v40n10p3672-3684.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/9790/files/tipsj+v40n10p3672-3684.pdf"},"version_id":"fce6a48f-9ea3-4b71-85ce-2c37c25ac812"}]},"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":"制約付き不規則メッシュ上でのwrinkly曲面の形成","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"制約付き不規則メッシュ上でのwrinkly曲面の形成"}]},"item_type_id":"16","owner":"3","path":["1519"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-10-02"},"publish_date":"2009-10-02","publish_status":"0","recid":"9790","relation_version_is_last":true,"title":["制約付き不規則メッシュ上でのwrinkly曲面の形成"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:57:21.476796+00:00"}
