AI-Driven 3D/4D Content Generation, Editing, and Animation Using Diffusion Models and Gaussian Splatting: A Narrative Review
Abstract
The convergence of diffusion models and 3D Gaussian Splatting (3D -GS) has catalyzed a paradigm shift in AI-driven 3D/4D content creation, enabling high-quality generation, editing, and animation from natural language instructions. This narrative review syn thesizes representative works published between 2023 and 2025 across four interconnected sub-areas: text-to-3D/4D generation, 3D scene editing, dynamic scene animation, and motion and video generation. Through comparative analysis of representation types, supervision strategies, and temporal modeling approaches, we identify convergent design principles—coarse- to-fine optimization in distillation-based methods, explicit representations, regularization against score - distillation variance, and decomposition for controllability—that recur across sub-areas. We catalog six critical limitations and propose concrete directions for improvement for each. This review serves as a foundational reference for researchers entering this rapidly evolving field.
