Hyperplane is used to expresses the position and forms of a spatial object of various dimensions. The hyperplanes are used to split a complex of convex polytopes into HA-faces. Each HA-face has its position vector, and the position vectors are used to evaluate the spatial operations: intersection, the union and the difference of complexes of convex polytopes in any dimension. First, we introduce the sign vector, which is the database representation of the position vector. Second, we present the conversion algorithms between position vectors and sign vectors of the complex model in any dimension. Third, we propose algorithms for compressing and uncompressing the sign vector to be stored in the database data. These algorithms are invoked when evaluating spatial operations. A spatial data model named HA-face-complex model is implemented on an object database system based on the sign vector. We also give the results of experimental tests to evaluate the data size of spatial database and speeds up the geometric operations.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"382","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告データベースシステム(DBS)"}],"bibliographicPageStart":"377","bibliographicIssueDates":{"bibliographicIssueDate":"2004-07-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"72(2004-DBS-134)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":19169,"updated":"2025-01-22T22:20:43.424745+00:00","links":{},"created":"2025-01-18T22:51:42.482821+00:00"}
