Turbo4DGen: Ultra-Fast Acceleration for 4D Generation
arXiv:2603.29572v2 Announce Type: replace-cross Abstract: 4D generation, or dynamic 3D content generation, integrates spatial, temporal, and view dimensions to model realistic dynamic scenes, playing a foundational role in advancing world models and physical AI. However, maintaining long-chain consistency across both frames and viewpoints through the unique spatio-camera-motion (SCM) attention mechanism introduces substantial computational and memory overhead, often leading to out-of-memory (OO…
