Pose-Free Feed-Forward 3D Inpainting via Learnable Mask Attention and Support Token Refinement

FreeInpaint is a feed‑forward 3D inpainting framework that reconstructs complete, geometrically consistent scenes directly from unposed multi‑view images with masked regions. It extends a 3D foundation model by propagating masked areas across views, using a Learnable Mask Attention mechanism to maintain reliable cross‑view correspondences and a Support Token Refinement strategy that injects diffusion‑generated auxiliary tokens for high‑fidelity completion. Experiments on diverse datasets show that FreeInpaint delivers superior inpainting quality without requiring pre‑computed camera poses, while maintaining fast inference speed.

LIFT: Layout-In-Future Video Generation under Large Viewpoint Change via On-Policy Self-Distillation

LIFT is a unified image‑to‑video generation framework that adds Layout‑In‑Future control, letting users specify what should appear and where in a future view. It addresses the limitation of existing camera controls and text prompts by using the last‑frame layout as an explicit signal for the desired future scene, especially under large viewpoint changes. To handle sparse layout guidance, LIFT employs on‑policy self‑distillation to transfer knowledge from a dense‑layout teacher to a last‑frame‑layout student, and introduces the LIFT‑Vista dataset with large viewpoint changes and consistent layout annotations. Experiments demonstrate that LIFT improves video quality, future‑layout controllability, and camera controllability compared to other methods.

DepthEvidence: Unifying Metric Depth Prediction and Geometric Reasoning in Multimodal Language Models

DepthEvidence is a 4B multimodal language model that integrates dense metric depth predictions into language generation. It employs a camera‑conditioned decoder to produce full‑resolution depth maps and a dense‑to‑language interface that converts these predictions into object‑aligned geometry tokens. The model is trained with geometric supervision and instruction tuning, and it sets new state‑of‑the‑art results on a Depth‑VQA benchmark and on instance‑level metric depth estimation across nine datasets.

ThinkBLOX: 3D Indoor Scene Generation with Progressive Reasoning

While traditional graphics methods often synthesize 3D indoor scenes autoregressively or hierarchically, recent vision-language model (VLM)-based generators predominantly adopt a one-shot paradigm where the full layout is planned at once. This one-shot approach often requires global re-optimization or complete reconstruction during interactive editing (e.
