Edit4D: Editable 4D Scene Generation with Textual Control

Edit4D is a new text‑to‑4D scene generation framework that builds editable 4D scenes by separately modeling background and dynamic characters. It decomposes user instructions into stage‑specific prompts for background, character, and composition, then uses text‑to‑image, camera‑conditioned priors, and image‑conditioned video priors to synthesize multi‑view images, reconstruct 3D Gaussian splatting backgrounds, animate characters into 4D meshes, and finally compose and refine the scene with text‑guided segmentation and contact‑aware optimization. This pipeline allows controllable camera motion, flexible object‑level editing, and practical construction of editable 4D scenes.

MATE4D: Matrix-Guided Editable 4D Generation from a Single Image

MATE4D is a framework that transforms a single image into editable dynamic 4D content. It builds a spatio-temporal multi-view image matrix with text-guided background manipulation, then optimizes 3D Gaussian primitives and animates them with a lightweight deformation module. The approach yields scenes with more faithful geometry, smoother temporal behavior, and consistent background edits, outperforming baselines on Objaverse-XL and Diffusion4D.

Chat-Edit-3D++: Interactive 3D and 4D Scene Editing via Large Language Models

The paper introduces Chat-Edit-3D++ (CE3D++), an interactive 3D and 4D scene editing system that uses a Hash-Atlas network to separate 2D editing from 3D reconstruction. CE3D++ employs a large language model to accept arbitrary textual input, interpret user intent, and autonomously invoke appropriate visual models, enabling multi‑round dialogue and diverse editing effects. The approach is extended to monocular 4D scenes by adding motion constraints and a trajectory dataset, allowing a smaller LLM to schedule up to 30 visual tools accurately.

4DSynth: Controllable Procedural World Synthesis for Dynamic Embodied Simulation

4DSynth is a controllable procedural system that transforms natural-language descriptions, blueprint masks, or single photographs into editable 4D environments featuring explicit geometry, animated actors, collision-free trajectories, and physics-ready simulation states. The system unifies animation, camera planning, rendering, and task generation within a single geometry-grounded representation, enabling scalable creation of dynamic embodied simulation scenes. Using 4DSynth, the authors built 4DSynth-Nav, an interactive navigation benchmark that demonstrates the reproducibility and tunability of procedural failures across vision‑language models.

SimWorlds: A Multi-Agent System for Dynamic 3D Scene Creation

LLM agents are increasingly used to translate natural language into 3D scenes in a procedural way, but existing systems focus on static output. Dynamic 4D scenes from text alone, in which liquids flow, particles emit, rigid bodies cascade, and articulated mechanisms move, remain largely unexplored despite their value as editable content and as physics-grounded training data for video generation and embodied AI.

SkelGen4D: Weakly-Supervised Skeleton-Based 4D Generation for Text-Driven Mesh Animation

We study 4D generation to synthesize temporally coherent sequences of 3D geometry for animation and content creation. In contrast to existing SDS-based optimization methods and video-driven animation approaches, we adopt a skeleton-driven animation framework aligned with standard industrial pipelines, which enables explicit control and editing.

VINCIE-NExT: Unlocking Video Editing from Images via In-Context Modeling

VINCIE‑NExT is a unified framework that transfers image editing capabilities to video editing by using in‑context visual demonstrations. It decomposes video editing into a chain of sub‑tasks (Video → Image → Image → Video), routing editing intent through the image domain and enabling joint training from heterogeneous image and video data under a single diffusion objective. The method introduces a novel position encoding to link image demonstrations and video frames, allowing pixel‑faithful appearance propagation, and supports test‑time scaling through progressive diffusion stages.

4DStreamCtrl: Interactive Video Generation with Online 4D Control

The paper introduces 4DStreamCtrl, a system that unifies camera motion, object trajectories, and depth into a single 3D point‑track representation, enabling joint control, depth editing, and motion transfer in a single forward pass. By mining in‑the‑wild video for 3D motion supervision and encoding it with a lightweight Geometric Motion Head, the authors train a causal streaming student that can generate arbitrarily long videos in just four denoising steps, achieving 20 FPS on a single high‑end GPU for 480p video. This approach outperforms prior camera‑only, 2D, and offline‑3D methods in motion‑control precision while maintaining temporal coherence over hundreds of frames, thereby enabling interactive 4D‑controllable streaming generation for the first time.
