Differentiable 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 ...
EPFL2022Scene Decomposition and Relighting from Image Collections in Neural Rendering
The focus of our research is to generate controllable photo-realistic images of real-world scenes from existing observations, i.e., the inverse rendering problem. The approaches we focus on are those through neural rendering, utilizing neural network to de ...
2022Light Path Gradients for Forward and Inverse Rendering
Physically based rendering is a process for photorealistic digital image synthesis and one of the core problems in computer graphics. It involves simulating the light transport, i.e. the emission, propagation, and scattering of light through a virtual scen ...
EPFL2021Monte Carlo Estimators for Differential Light Transport
Wenzel Alban Jakob, Tizian Lucien Zeltner, Sébastien Nicolas Speierer
Physically based differentiable rendering algorithms propagate derivatives through realistic light transport simulations and have applications in diverse areas including inverse reconstruction and machine learning. Recent progress has led to unbiased metho ...
ASSOC COMPUTING MACHINERY2021Raytraverse: Navigating the Lightfield to Enhance Climate-Based Daylight Modeling
Marilyne Andersen, Jan Wienold, Stephen William Wasilewski
We propose a new method for climate-based daylight modeling (CBDM) based on simulating and evaluating only the most important features. By adaptively sampling the temporal lightfield that describes daylight in buildings, our method escapes the curse of dim ...
2021Synchrotron-based phase-contrast micro-CT as a tool for understanding pulmonary vascular pathobiology and the 3-D microanatomy of alveolar capillary dysplasia
This study aimed to explore the value of synchrotron-based phase-contrast microcomputed tomography (micro-CT) in pulmonary vascular pathobiology. The microanatomy of the lung is complex with intricate branching patterns. Tissue sections are therefore diffi ...
AMER PHYSIOLOGICAL SOC2020Radiative Backpropagation: An Adjoint Method for Lightning-Fast Differentiable Rendering
Wenzel Alban Jakob, Sébastien Nicolas Speierer, Merlin Eléazar Nimier-David
Physically based differentiable rendering has recently evolved into a powerful tool for solving inverse problems involving light. Methods in this area perform a differentiable simulation of the physical process of light transport and scattering to estimate ...
ASSOC COMPUTING MACHINERY2020Photorealistic modelling of metals from first principles
Nicola Marzari, Gianluca Prandini, Gian-Marco Rignanese
The colours of metals have attracted the attention of humanity since ancient times, and coloured metals, in particular gold compounds, have been employed for tools and objects symbolizing the aesthetics of power. In this work, we develop a comprehensive fr ...
