This workshop focuses on recent advances in video generative models and their applications in 3D and 4D generation and reconstruction. Topics include camera- and motion-controlled video synthesis, large-scale 3D/4D reconstruction, neural rendering, and generative model-guided pipelines. A central focus is geometry-free novel view synthesis with video diffusion models, enabling spatial control without explicit 3D geometry. The program also covers the distillation of temporal models into spatial representations. By highlighting these developments, the workshop aims to chart the path toward more controllable, photorealistic, and efficient generative pipelines that unify video generation with 3D and 4D reconstruction.
