But there has been no research intended for a Unit-Origami that is constructed from many elemental units with the same shape. In this paper, we focus on the most popular Unit-Origami: Sonobe-unit, and we present a Unit-Origami modeling system which can generate an approximated shape of a 3D polygon model. At first, to meet the geometric constraints of Sonobe-unit construction, we deform a given 3D polygon model. Then, we voxelize the deformed model with regular tetrahedra and octahedra. Finally, we arrange Sonobe-units on those voxel surfaces unit by unit. In this way, we can make a Unit-Origami work which approximates an arbitrary 3D polygon model.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告グラフィクスとCAD（CG）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2010-11-01","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2010-CG-141"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:29:49.663899+00:00","id":70752,"links":{}}
