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…
Real-time Neural Woven Fabric Rendering
Xiang Chen, Lu Wang, Beibei Wang
Woven fabrics are widely used in applications of realistic rendering, where real-time capability is also essential. However, rendering realistic woven fabrics in real time is chall…
Multiple-bounce Smith Microfacet BRDFs using the Invariance Principle
Yuang Cui, Gaole Pan, Jian Yang +3
Smith microfacet models are widely used in computer graphics to represent materials. Traditional microfacet models do not consider the multiple bounces on microgeometries, leading…
BSDF Importance Baking: A Lightweight Neural Solution to Importance Sampling General Parametric BSDFs
Yaoyi Bai, Songyin Wu, Zheng Zeng +2
Parametric Bidirectional Scattering Distribution Functions (BSDFs) are pervasively used because of their flexibility to represent a large variety of material appearances by simply…
Neural BRDFs: Representation and Operations
Jiahui Fan, Beibei Wang, Miloš Hašan +2
Bidirectional reflectance distribution functions (BRDFs) are pervasively used in computer graphics to produce realistic physically-based appearance. In recent years, several works…
SpongeCake: A Layered Microflake Surface Appearance Model
Beibei Wang, Wenhua Jin, Miloš Hašan +1
In this paper, we propose SpongeCake: a layered BSDF model where each layer is a volumetric scattering medium, defined using microflake or other phase functions. We omit any reflec…
Constant-Cost Spatio-Angular Prefiltering of Glinty Appearance Using Tensor Decomposition
Hong Deng, Yang Liu, Beibei Wang +4
The detailed glinty appearance from complex surface microstructures enhances the level of realism, but is both space- and time-consuming to render, especially when viewed from far…
Position-free Multiple-bounce Computations for Smith Microfacet BSDFs
Beibei Wang, Wenhua Jin, Jiahui Fan +3
Bidirectional Scattering Distribution Functions (BSDFs) encode how a material reflects or transmits the incoming light. The most commonly used model is the Microfacet BSDF. It comp…
