A Full-Wave Reference Simulator for Computing Surface Reflectance
Computing light reflection from rough surfaces is an important topic in computer graphics. Reflection models developed based on geometric optics fail to capture wave effects such as diffraction and interference, while existing models based on physical opti ...
ASSOC COMPUTING MACHINERY2023Efficient and Accurate Physically-Based Differentiable Rendering
Physically-based rendering algorithms generate photorealistic images of virtual scenes. By simulating light paths in a scene, complex physical effects such as shadows, reflections and volumetric scattering can be reproduced. Over the last decade, physicall ...
EPFL2022Differentiable Physically Based Rendering: Algorithms, Systems and Applications
Physically based rendering methods can create photorealistic images by simulating the propagation and interaction of light in a virtual scene. Given a scene description including the shape of objects, participating media, material properties, etc., the sim ...
EPFL2022Modeling specular transmission of complex fenestration systems with data-driven BSDFs
A Bidirectional Scattering Distribution Function (BSDF) describes how light from each incident direction is scattered (reflected and transmitted) by a simple or composite surface, such as a window shade. Compact, tabular BSDFs may be derived via interpolat ...
2021DepthInSpace: Exploitation and Fusion of Multiple Video Frames for Structured-Light Depth Estimation
François Fleuret, Camilla Carta
We present DepthInSpace, a self-supervised deep-learning method for depth estimation using a structured-light camera. The design of this method is motivated by the commercial use case of embedded depth sensors in nowadays smartphones. We first propose to u ...
IEEE2021Practical Product Path Guiding Using Linearly Transformed Cosines
Path tracing is now the standard method used to generate realistic imagery in many domains, e.g., film, special effects, architecture etc. Path guiding has recently emerged as a powerful strategy to counter the notoriously long computation times required t ...
WILEY2020Neural BTF Compression and Interpolation
The Bidirectional Texture Function (BTF) is a data-driven solution to render materials with complex appearance. A typical capture contains tens of thousands of images of a material sample under varying viewing and lighting conditions. While capable of fait ...
WILEY2019A Learned Shape-Adaptive Subsurface Scattering Model
Wenzel Alban Jakob, Delio Aleardo Vicini
Subsurface scattering, in which light refracts into a translucent material to interact with its interior, is the dominant mode of light transport in many types of organic materials. Accounting for this phenomenon is thus crucial for visual realism, but exp ...
ASSOC COMPUTING MACHINERY2019Quantifying the Error of Light Transport Algorithms
This paper proposes a new methodology for measuring the error of unbiased physically based rendering algorithms. The current state of the art includes mean squared error (MSE) based metrics and visual comparisons of equal-time renderings of competing algor ...
