AIGC is getting so competitive nowadays that 2D/3D/video content is no longer enough—4D has entered the scene 😂. Quickly sharing some of the recent 4D generation algorithms I came across—some are almost ready for use. Note: here, 4D refers to 3D models with movement (4D models), and videos that allow switching viewpoints during playback (4D spatial scenes).

Animate124: Converts a single static image into a 3D video based on text descriptions, achieving a leap from 2D to 4D. This technology leverages a three-stage optimization and multi-diffusion prior, creating a unique animation experience.

4D-fy: Combines variational SDS and text-to-image models (T2I) to enhance the 4D generation process. This algorithm enhances visual effects through mixed gradient supervision, showcasing its unique advantages in text-driven four-dimensional creation.
