The paper introduces a benchmark called Shedding Light to evaluate how well generative image models understand and reproduce lighting. The benchmark tests models by asking them to inpaint a simple object, called a light probe, into real photographs and then compares the generated probe to the ground truth to assess lighting direction, colour, and radiance. The authors provide a scalable protocol and open-source code and data for systematic assessment of photometric accuracy in future models.
The paper introduces a prior-guided material reparameterization for physically based inverse rendering, leveraging learned material predictions to restrict the optimization space without altering the photometric objective. By fusing multi-view predictions onto a mesh and constructing a permutohedral lattice in prior feature space, surface points with similar predictions share material variables, which are jointly optimized with geometry and illumination. Experiments on synthetic benchmarks and Stanford-ORB show improved material decomposition and relighting, with PSNR gains of 1.5–2.5 dB over strong baselines and a faster optimization schedule that maintains high relighting quality.
The paper introduces a real‑time technique for reconstructing fully integrated pixel radiance in volumetric media under both direct and ambient illumination. It bypasses expensive path‑traced radiance estimates by inferring the final light‑transport solution from compact scene features and statistics, using an attention‑augmented image‑to‑image network. The method achieves high reconstruction accuracy in challenging volumetric cloud scenarios while maintaining stable computational cost regardless of camera zoom or volume density.
