Many applications generate meshes from point clouds to render high-quality surfaces, but these approaches require costly computation in preprocessing or manual parameter tuning. To achieve fast and high-quality rendering by directly using point clouds, methods have been proposed to estimate the occluded points in screen space. However, it is necessary to adjust the parameter according to the density of the points. In this paper, we studied an estimation method that does not depend on adjustment according to the density by considering the local density of the points in screen space.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告グループウェアとネットワークサービス（GN）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-01-13","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"2022-GN-115"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":215848,"links":{}}
