4. Alignment Is All You Need For X-to-4D Generation
- Source: arXiv
- Published: 2026-07-02T17:59:57Z
- Why it matters: Adds a stronger benchmark in 3D and visual generation.
- Summary: We further propose the X4D dataset, which integrates prompt, image, video, and 3D data for benchmarking. This paper presents Align4D, a flexible framework that translates any-modal input into coherent video-3D pairs, using video to guide 4D motion and 3D data to shape 4D geometry. Alignment All You Need X-to-4D is best read as a stronger benchmark in 3D and visual generation.

5. WorldDirector: Building Controllable World Simulators with Persistent Dynamic Memory
- Source: arXiv
- Published: 2026-07-02T17:59:59Z
- Why it matters: Adds an implementation framework in 3D and visual generation. Stands out for useful downstream control.
- Summary: Title: WorldDirector: Building Controllable World Simulators with Persistent Dynamic Memory Base summary: We present WorldDirector, a highly controllable video world model framework designed for persistent dynamic object memory and unrestricted viewpoint…. Unlike existing world models that entangle physical dynamics with pixel rendering and rely on continuous visual observation to sustain motion, our framework explicitly decouples semantic motion orchestration from visual generation. WorldDirector is best read as an implementation framework in 3D and visual generation.
