In this study, we propose affine-transformed ray alignment as a novel method to reduce the time complexity of ray tracing by combining multiple rays into a single ray using affine transformation. As a result of experiments applying the proposed method to primary ray traversal, it was confirmed that the time complexity can be reduced with little increase in spacial complexity and without causing errors in the rendered images.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告コンピュータグラフィックスとビジュアル情報学（CG）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2022-03-04","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"2","bibliographicVolumeNumber":"2022-CG-185"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217335,"updated":"2025-01-19T15:32:09.084531+00:00","links":{},"created":"2025-01-19T01:17:49.971791+00:00"}
