To render translucent objects, it is necessary to take into account the subsurface scattering of light. However, rendering translucent objects with the subsurface scattering takes long time. In our method, virtual points are set around the object uniformly. The intensities of the subsurface scattering of light are calculated at each virtual point. The intensities of points that represent the translucent object are interpolated by the intensities of the virtual points. Our method can render about 500,000 points with the subsurface scattering in real-time.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"62","bibliographic_titles":[{"bibliographic_title":"情報処理学会研究報告グラフィクスとCAD（CG）"}],"bibliographicPageStart":"57","bibliographicIssueDates":{"bibliographicIssueDate":"2006-02-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"18(2006-CG-122)","bibliographicVolumeNumber":"2006"}]},"relation_version_is_last":true,"weko_creator_id":"1"},"id":38101,"updated":"2025-01-22T13:30:39.535199+00:00","links":{},"created":"2025-01-18T23:05:47.150787+00:00"}
