The background art, in many cases that is a Landscape Painting, is generally used in animation productions. One background art and multiple layers of moving characters compose a scene. The background art is one of most important factor for making the impression of an animation. We propose, in particular, a NPR technique that can reproduce painting techniques characteristic of background art such as leaf painting based on just a few colors, shading to produce a spherical effect, and aerial perspective. This technique can generate dynamic background art having a swaying motion in the wind by applying the animation generation tool for swaying trees developed by the authors 1),2) The proposed method, in contrast, is based on a painting technique for background art, which enables it to pick up features of the target work of art and to reproduce its style.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"1499","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"1489","bibliographicIssueDates":{"bibliographicIssueDate":"2008-03-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"3","bibliographicVolumeNumber":"49"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"コンピュータグラフィックス"}]},"weko_creator_id":"1"},"id":9641,"updated":"2025-01-23T03:19:14.599465+00:00","links":{}}
