Fused View-Time Attention and Feedforward Reconstruction for 4D Scene Generation

NeurIPS 2025poster

We propose the first framework capable of computing a 4D spatio-temporal grid of video frames and 3D Gaussian particles for each time step using a feed-forward architecture. Our architecture has two main components, a 4D video model and a 4D reconstruction model. In the first part, we analyze curren…

GTR: Improving Large 3D Reconstruction Models through Geometry and Texture Refinement

ICLR 2025poster

We propose a novel approach for 3D mesh reconstruction from multi-view images. We improve upon the large reconstruction model LRM that use a transformer-based triplane generator and a Neural Radiance Field (NeRF) model trained on multi-view images. We introduce three key components to significantly…

Lightweight Predictive 3D Gaussian Splats

ICLR 2025poster

Recent approaches representing 3D objects and scenes using Gaussian splats show increased rendering speed across a variety of platforms and devices. While rendering such representations is indeed extremely efficient, storing and transmitting them is often prohibitively expensive. To represent large-…

Towards Physical Understanding in Video Generation: A 3D Point Regularization Approach

NeurIPS 2025poster

We present a novel video generation framework that integrates 3-dimensional geometry and dynamic awareness. To achieve this, we augment 2D videos with 3D point trajectories and align them in pixel space. The resulting 3D-aware video dataset, PointVid, is then used to fine-tune a latent diffusion mod…

Wonderland: Navigating 3D Scenes from a Single Image

CVPR 2025poster

This paper addresses a challenging question: how can we efficiently create high-quality, wide-scope 3D scenes from a single arbitrary image?Existing methods face several constraints, such as requiring multi-view data, time-consuming per-scene optimization, low visual quality, and distorted reconstru…
