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.

Dream4D is a new framework for generating spatiotemporally coherent 4D content. It uses a two‑stage pipeline: first, few‑shot learning predicts optimal camera trajectories from a single image; second, a pose‑conditioned diffusion process creates geometrically consistent multi‑view sequences that are converted into a persistent 4D representation. The method uniquely combines rich temporal priors from video diffusion models with geometric awareness from reconstruction models, achieving higher quality metrics such as mPSNR and mSSIM compared to existing approaches.
