Due to the advancement of simulation and rendering techniques, realistic animations can be created, but some problems still remain: the simulation and the rendering require huge computation cost, and tedious parameter adjustment is needed to create the desired results. To address this problem, a post processing method for transferring turbulence has been proposed. This method can reduce the computational cost for creating the desired fluid flows by transferring the turbulent motion from a high-resolution flow to another low-resolution flow. However, this method contains computationally expensive processes, so its computation time is still long. We attempt to speed up this previous method by reconstructing the 3D flow based on the 2D flow with transferred turbulence. Our method achieves approximately 12 times faster computation than the previous method while maintaining the same visual quality as the previous method.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"5","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":"5","bibliographicVolumeNumber":"2022-CG-185"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":217338,"updated":"2025-01-19T15:32:05.949879+00:00","links":{},"created":"2025-01-19T01:17:50.141852+00:00"}
