Realistic Rendering of Woven Surface using Procedural Bump Mapping
Young-Min Kang · Journal of Korea Game Society · 2010
ABSTRACT In this paper, an procedural approach to photorealistic rendering of woven fabric material is proposed. Previously proposed procedural approaches to fabric rendering have the disadvantage that the rendering result is not sufficiently realistic. In order to enhance the realism, researchers employed example-based approaches. However, those methods have serious disadvantage that they require huge amount of storage for the various reflectance properties of diverse materials. The proposed method can express the reflectance on weft and warp yarns by alternating the anisotropic reflectance on yarns. In addition, we propose the proposed method procedurally models the bumpy yarn structure of woven fabric to obtain plausible rendering results. The proposed method can efficiently reproduce realistic virtual fabric without any reflectance data sets.Keyword : Photorealistic rendering, woven fabric, alternating anisotropy. 접수일자 : 2010년 02월 17일 일차수정 : 2010년 03월 30일 심사완료 : 2010년 04월 14일※ 본 연구는 정보통신연구진흥원의 IT산업원천기술개발사업의 일환으로 수행한 연구[2006-S-045-1]를 바탕으로, 지식 경제부 및 정보통신산업진흥원의 대학 IT 연구센터 지원 사업의 연구결과로 수행되었음 [NIPA-2010(C-1090-1021-0006)]
