🍺 LagerNVS (CVPR 2026) 🍺 LagerNVS is a generalizable, feed-forward, real-time Novel View Synthesis network which - performs rendering in real time, - generalizes to in-the-wild data, - works with and without known source cameras, - sets a new state-of-the-art among deterministic methods, - can be paired with a diffusion decoder for generative extrapolation. LagerNVS shows that 3D biases are useful for Novel View Synthesis but explicit 3D representations are not required to achieve them. We use 3D biases in (1) architecture design and (2) pre-training: (1) In NVS with explicit 3D representations (3DGS, NeRF) reconstruction is typically difficult and slow, but rendering is much faster and simpler. We mimic this process in the network design: we use a large (1B params) encoder and a small, lightweight decoder (ViT-B). This allows increasing the network capacity while still achieving real-time rendering. (2) The encoder, initialized from VGGT, was pre-trained with 3D reconstruction objectives, making the initial features 3D aware. Both substantially improve performance.

@CVPR @gabTrivv I don’t have anything assigned on 15 December. Can I assume I won’t need to review for this cycle?

@gabTrivv No delays have been discussed. Area Chairs have submitted their recommendations, our PCs are finalizing the reviewer/paper assignments. This final match stage with thousands of papers/reviewers can be time consuming. Stay tuned.

@tomlikestocode @AIatMeta It is more appropriate for NeRFs than for meshes, as there is no mesh ground truth (those are the real-world data!). In fact, the dataset contains gaussian spats reconstruction from the source videos.

@AIatMeta Does this dataset support NeRF-based models, or is it more optimized for mesh-based training?

📣 New research from GenAI at Meta, introducing Meta 3D Gen: A new system for end-to-end generation of 3D assets from text in <1min. Meta 3D Gen is a new combined AI system that can generate high-quality 3D assets, with both high-resolution textures and material maps end-to-end, producing results that are superior to existing solutions — at 3-10x the speed of existing work in this space.

@bookingcom Deeply concerned about your security practices.Experienced a booking cancellation (the hotel vanished from the site), followed by fraudulent charges from Brazilian sites on the used card. It raises serious questions.Leaving for vacation tomorrow without a secure card!

Novel-view synthesis has achived great success, but can we also synthesize the sound at novel viewpoints? We present "Novel-view Acoustic Synthesis" @CVPR Tues PM. We introduce the very first NVAS formulation, multi-view audio-visual datasets, and approach to this problem.

@virginmedia What an honest company can do in this situation is to drop exit fees for customers who need to switch to a more reliable operator.

Unfortunately we have seen a repeat of an earlier issue which is causing intermittent broadband connectivity problems for some Virgin Media customers. We apologise again to those impacted, our teams are continuing to work flat out to find the root cause of the problem and fix it.
