But, beforehand we have to think over what types and how many blocks we need and how we can combine them, because we need so many blocks and a large working space to complete an entire object. In this paper, we propose a LEGO block modeling system which can automatically generate an approximated shape by LEGO block from an arbitrary 3D polygon model considering the constraints such as block resolution Our system also provides a physical stability evaluation function. We demonstrate actual work production such as a Stanford Bunny constructed from more than 2,200 LEGO blocks, and we discuss usability and effectiveness of our system.","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":"2013-11-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"8","bibliographicVolumeNumber":"2013-CG-153"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"updated":"2025-01-21T13:24:08.212148+00:00","links":{}}
