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…
On the Properties of the Anisotropic Multivariate Hermite-Gauss Functions
Shlomi Steinberg, Ömer Eğecioğlu, Ling-Qi Yan
The Hermite-Gauss basis functions have been extensively employed in classical and quantum optics due to their convenient analytic properties. A class of multivariate Hermite-Gauss…
Rendering Discrete Participating Media with Geometrical Optics Approximation
Jie Guo, Bingyang Hu, Yanjun Chen +3
We consider the scattering of light in participating media composed of sparsely and randomly distributed discrete particles. The particle size is expected to range from the scale o…
