PureLight: Learning Complex Luminaires with Light Tracing
Pedro Figueiredo, Zixuan Li, Beibei Wang +2
We propose a neural formulation for estimating the appearance of complex luminaires. We focus on challenging luminaires with complex light transport (e.g., small emitters enclosed…
Macrofacet Theory for Gaussian Process Statistical Surfaces
Minghao Huang, Yuang Cui, Beibei Wang +1
We present macrofacet theory to extend microfacet theory from the micro-space to the macro-space. This is achieved by transforming surfaces into volumetric representations that pre…
Fiber-level Woven Fabric Capture from a Single Photo
Zixuan Li, Pengfei Shen, Hanxiao Sun +7
Accurately rendering the appearance of fabrics is challenging, due to their complex 3D microstructures and specialized optical properties. If we model the geometry and optics of fa…
A Dynamic By-example BTF Synthesis Scheme
Zilin Xu, Zahra Montazeri, Beibei Wang +1
Measured Bidirectional Texture Function (BTF) can faithfully reproduce a realistic appearance but is costly to acquire and store due to its 6D nature (2D spatial and 4D angular). T…
