초록

본 논문에서는 측정된 양방향 반사 분포 함수(BRDF)와 같은 데이터 없이 사실적인 직물 표면 렌더링이 가능한 효율적인 방법을 제안한다. 제안된 기법은 광선 추적 기반의 오프라인 렌더러와 게임과 같은 실시간 응용에 모두 적용할 수 있다. 제안된 기법은 교호적(alternating) 이방성 반사와 변형된 미세면 분포 함수를 이용하여 직조 표면을 표현한다. 실에 대한 절차적 모델링은 직물의 표면을 효과적이며 효율적으로 표현할 수 있게 한다. 실험결과는 제안된 기법을 통해 상호작용적 응용에서도 다양한 직조물 표면을 사실적으로 렌더링할 수 있음을 보이고 있다.

In this paper, an efficient method is proposed to produce photorealistic images of woven fabrics without empirical data such as the measured BRDFs(bidirectional reflectance distribution functions). The proposed method is applicable both to ray tracer based offline renderers and to realtime applications such as games. The proposed method models the reflectance properties of woven fabric with alternating anisotropy and deformed MDF(microfacet distribution function). The procedural modeling of the yarn structure effectively and efficiently reproduces plausible rendering of woven fabric. The experimental results show the proposed method can be successfully applied to photorealistic rendering of diverse woven fabric materials even in interactive applications.
