I will also be there presenting LuxRemix! Looking forward to your visit 🤗 BTW, I just released our massive 360 synthetic rendering dataset w/ light decomposition. Please check the thread.
Today, we’re presenting LuxRemix at #CVPR2026 — 10:45 poster session, poster #102! Decompose indoor lighting into individual light sources from one image, then remix it (on/off, color, intensity) with real-time 3DGS relighting. Come say hi 👋 luxremix.github.io

Fortunate to help @yxue_yxue on this project during our Meta internship 😃. GeoRelight follows the research trajectory of DifffusionRenderer and UniRelight and delivers a significant quality improvement in relighting and geometry reconstruction for general human captures.
#CVPR2026 Highlight How to make relighting more photorealistic? Make reconstruction happening together! GeoRelight jointly resolves Geometry, Instrinsics, and Relighting, and proves they have mutual benefit (Geometry helps you know shadow and shading) yuxuan-xue.com/georelight

We open-sourced the code and model for UniRelight! 🎉 Given an input video and a target lighting configuration, our method jointly predicts a relit video and its corresponding albedo. Code: github.com/nv-tlabs/UniRelig… Model: huggingface.co/nvidia/UniRel…
🚀 Introducing UniRelight, a general-purpose relighting framework powered by video diffusion models. 🌟UniRelight jointly models the distribution of scene intrinsics and illumination, enabling high-quality relighting and intrinsic decomposition from a single image or video.

My dear front-end developers (and anyone who’s interested in the future of interfaces): I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept): Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

I also took a picture of this classic place for the teaser demo of our #CVPR26 paper LuxRemix (luxremix.github.io/) 😄 I used to love to sit there on Saturday afternoon, hoping Einstein could give me some research ideas 🤣 Credits also to @c_richardt for composing the vid.

Amazing 🤯
oh my.. Nano Banana Pro is so crazy it can analyse any film scene and tell you how it was shot, what camera, lens & lighting used .. and even tell you exact settings, hows this even possible.. free to try on Higgsfield now 10 crazy examples:

🚀Beyond the easy video types we previously used for model training, I also tried a lot of vibe coding to add an experimental support for physics-based object drop simulation. I never get tired of watch such object dropping videos 😆
