Moreover, a tedious trial-and-error process is inevitable to produce the desired effect of fog; we need to render an image with different parameter settings until the desired effect is obtained. Due to the high computational cost for generating CG images, this process requires a great deal of time and effort. The computational cost is particularly expensive when we need to take into the complex scattering phenomena inside the participating media such as fog. In this study, we propose a method to render the desired appearance of fog. We estimate the fog parameters that reproduce the desired appearance of the image. Our method can reduce the time and effort required for trial and error to find the appropriate parameters of the fog.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"4","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":"2021-08-18","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"4","bibliographicVolumeNumber":"2021-CG-183"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"id":212391}
