Real-time Rendering of Layered Materials with Anisotropic Normal Distributions

SIGGRAPH ASIA 2019 Technical Briefs

This paper proposes a lightweight bidirectional scattering distribution function (BSDF) model for layered materials with anisotropic reflection and refraction properties 구글 크롬 전체 다운로드. In our method, each layer of the materials can be described by a microfacet BSDF using an anisotropic normal distribution function (NDF). Furthermore, the NDFs of layers can be defined on tangent vector fields, which differ from layer to layer 월요일이 사라졌다 자막. Our method is based on a previous study in which isotropic BSDFs are approximated by projecting them onto base planes. However, the adequateness of this previous work has not been well investigated for anisotropic BSDFs always on top. In this paper, we demonstrate that the projection is also applicable to anisotropicBSDFs and that they can be approximated by elliptical distributions using covariance matrices Enter your search terms to.
