Shedding Light: A Benchmark for Evaluating Lighting Understanding in Generative Image Models

Justine Giroux, Jack Oliver Hilliard, Yannick Hold-Geoffroy +2

Accurate modelling of illumination is central to realistic image synthesis and scene understanding. Yet, there is little exploration into whether image generative models are good a…

GRay: Ray Tracing 3D Gaussians Near the Speed of Splats

Yohan Poirier-Ginter, Jean-François Lalonde, George Drettakis

3D Gaussian Splatting (3DGS) is a popular representation for radiance field reconstruction, distinguished by the rendering speed of its rasterization-based renderer. While 3D Gauss…

Editable Physically-based Reflections in Raytraced Gaussian Radiance Fields

Yohan Poirier-Ginter, Jeffrey Hu, Jean-François Lalonde +1

Radiance fields such as 3D Gaussian Splatting allow real-time rendering of scenes captured from photos. They also reconstruct most specular reflections with high visual quality, bu…

Lighting in Motion: Spatiotemporal HDR Lighting Estimation

Christophe Bolduc, Julien Philip, Li Ma +3

We present Lighting in Motion (LiMo), a diffusion-based approach to spatiotemporal lighting estimation. LiMo targets both realistic high-frequency detail prediction and accurate il…

GimbalDiffusion: Gravity-Aware Camera Control for Video Generation

Frédéric Fortier-Chouinard, Yannick Hold-Geoffroy, Valentin Deschaintre +2

Recent progress in text-to-video generation has achieved remarkable realism, yet fine-grained control over camera motion and orientation remains elusive, especially with extreme tr…

Improving the color accuracy of lighting estimation models

Zitian Zhang, Joshua Urban Davis, Jeanne Phuong Anh Vu +2

Advances in high dynamic range (HDR) lighting estimation from a single image have opened new possibilities for augmented reality (AR) applications. Predicting complex lighting envi…
