In this method, shape control of the multiple suraces is difficult. Trimmed surface is used for interpolating a concave area and shape control of the trimmed surface was also difficult. In this research, we propose a method of interpolation of a non-four-sided (over 4) area using a single NBG (NURBS Boundary Gregory) patch. In this method, S^u or S^v is formed by subdividing the area into subpatches at C^0 continuous vertex and merging these subpatches after correcting the continuity. In this method, a non-four-sided (over 4) area can be interpolated by a single NBG patch. And a simple concave area can also be interpolated by a single NBG patch.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"718","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"710","bibliographicIssueDates":{"bibliographicIssueDate":"1999-02-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"40"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"コンピュータグラフィクス"}]},"weko_creator_id":"1"},"created":"2025-01-18T22:47:05.830548+00:00","id":12852,"links":{}}
