However, it takes a long time to create high-resolution results to express detailed motions of water. Furthermore, due to the expensive computational cost, it is very time-consuming to repeat the simulation to obtain the desired results. In this paper, we discuss a method of fitting the pre-computed high-resolution simulation data to the low-resolution simulation data. The overall behavior of the water flow is designed by the efficient low-resolution simulation. By deforming the high-resolution simulation data to fit the low-resolution simulation data, a high-resolution result with the desired behavior is generated. We use a particle-based method for the simulation of water. We discuss two deformation methods for the particle distribution: deformation along with the deformation of the terrain and deformation using principal component analysis on particle distribution.","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":"2021-10-29","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"2021-CG-184"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":213539,"updated":"2025-01-19T17:07:31.013404+00:00","links":{},"created":"2025-01-19T01:14:24.694321+00:00"}
