We propose a method to render these types of large scale data sets with interactive rate and developed an application independent library. In order to minimize run time file access overhead for the large data set, we designed a data format for a single large intermediate file which may amount to several hundreds of gigabyte, as well as implemented a mechanism for paging objects from an instance of the file. In the rendering process, optimization techniques such as culling, LOD, texture control are used in combined with paging. To support various types of applications, object modification feature is realized by saving a history file which can also be paged in at run time and can be merged to the single large file at a post processing phase.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"36","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告グラフィクスとCAD（CG）"}],"bibliographicPageStart":"31","bibliographicIssueDates":{"bibliographicIssueDate":"2004-11-26","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"121(2004-CG-117)","bibliographicVolumeNumber":"2004"}]},"relation_version_is_last":true,"weko_creator_id":"1"}}
